Since graduating from the INI’s Master of Science in Neuroimaging and Informatics (NIIN) program, Arvin Saremi (’17) hasn’t slowed down. He has coauthored four journal articles based on research he conducted with the INI’s Neda Jahanshad, PhD, during the master’s program, and is now a medical student at Case Western Reserve University, a top-25 ranked medical school for research.
“The NIIN program opened up many new doors for me—both in terms of opportunity and outlook,” Saremi says. “After exploring neuroimaging, I was able to enter medical school with a clear idea of my career interests from the beginning.”
During his year in the NIIN program, Saremi contributed to research at the INI’s Imaging Genetics Center, studying brain development in children with HIV, genetic markers associated with the volume of the hippocampus, and other topics. He recommends that future students seek out a faculty mentor at the institute and begin conducting research as soon as the program begins.
“The concepts taught in the program are incredibly complex. The best way to learn them is to actively apply them in research,” he says.
Because of the expertise he developed in diagnostic imaging during the NIIN program, Saremi was able to land a position in a neuroimaging lab just weeks after entering medical school. He says he’ll keep an open mind as he moves through the program but ultimately hopes to focus on neuroradiology.

For the first time, the INI has convened the research and clinical imaging communities of Southern California for an impactful annual workshop on high- and low-field Magnetic Resonance Imaging technologies. On October 12, the group convened on the USC Health Sciences Campus for a day of tours, tutorials and presentations that connected researchers from across the region and stimulated new lines of inquiry as well as novel research partnerships.
Danny JJ Wang, PhD, professor of neurology, director of imaging technology of innovation at INI and co-organizer of the workshop, started the day by welcoming guests to the institute and sharing a brief history of the INI and the Laboratory of Neuro Imaging Resource (LONIR), a platform for collaborative research in the neurosciences. Later, Wang led a tour of the institute and its Center for Image Acquisition (CIA), which houses both an ultra-high-field (UHF) 7-Tesla Siemens Terra MRI system and a 3-Tesla Siemens Prisma MRI system.
Presentations throughout the day included an in-depth discussion of high-performance-low-field (HPLF) MRI at USC by workshop co-organizer Krishna Nayak, PhD, a professor of electrical engineering at the Viterbi School of Engineering with joint appointments in radiology and biomedical engineering. Other topics, including clinical and research applications of UHF MRI, vascular imaging with UHF MRI, UHF coil developments, cardiac intervention and lung imaging with HPLF MRI, and more were also featured.
On July 1, Vishal Patel, MD, PhD, joined the INI as an assistant professor of radiology. Patel, who earned his doctoral degree in biomedical engineering, completed a residency in diagnostic radiology at the University of California, Los Angeles and a fellowship in neuroradiology at USC.
Patel’s research interests include MRI, diffusion imaging, tractography and machine learning. At the INI, he plans to apply his knowledge of computational MRI and artificial intelligence (AI) to improve diagnostic techniques for neuroradiologists.
“The goal is to establish USC, and in particular the INI, as a site where AI methods and techniques are developed, validated and made available for use to the greater neuroimaging community, including both researchers and clinicians,” Patel says.
AI holds promise for a number of clinical challenges. For instance, an MRI scanner may register images of very small brain lesions that the naked eye cannot detect, but researchers like Patel can build software that identifies subtle abnormalities present in the underlying imaging data. Ultimately, this technology can be used to detect tumors and classify them by cell-type and pathological grade, providing a precise and non-invasive way to diagnose brain cancer.
Patel’s research at USC will build on his previous work applying machine learning concepts to tumor identification and other clinical challenges. But now, he has a powerful new tool: the INI’s ultra-high field 7Tesla MRI scanner, which received FDA approval for clinical scanning last fall.
“The INI is proud to welcome Vishal to our team,” says Arthur W. Toga, PhD, provost professor at USC and director of the INI and the Laboratory of Neuro Imaging (LONI). “Applying his expertise in neuroradiology to our high-end clinical imaging system will undoubtedly lead to meaningful new discoveries.”
Toga and Patel have collaborated in the past and look forward to resuming their research together on a new clinical imaging study of patients with multiple sclerosis (MS).
“LONI was a phenomenal place during my graduate training and it continues to become more and more impressive, especially with the addition of clinical high-field imaging capabilities,” says Patel. “I’m excited to come on board and get to work in what I know to be an excellent environment for research.”

Faisal Rashid, a student in the INI’s Neuroimaging and Informatics master’s program, was sworn into the Los Angeles Police Department on January 4 as a reserve officer after nearly two years of interviews, background investigations, polygraph tests, extensive training, and medical, physical fitness and psychological examinations.
Rashid was inspired to join the academy while working as a project assistant in the lab of Paul Thompson, PhD, INI’s associate director. After studying how addiction, depression, post-traumatic stress disorder and other conditions affect brain health, Rashid says he began to understand how such issues contribute to crime and homelessness.
“Law enforcement officers are typically first responders to emergencies that involve individuals with mental health problems, trauma, or troubled adolescents. Sometimes, the right interaction with the right people can change the trajectory of someone’s life for the better," Rashid says, adding that it’s always been a priority for him to give back to Los Angeles, where he was born and raised.
He is currently assigned to the LAPD's Counter Terrorism and Special Operations Bureau. Moving forward, he hopes to study the relationship between mental health, trauma in childhood and adolescence, and crime.
On December 14, INI held its holiday party and 2nd annual Winter Games competition. While faculty and staff enjoyed festive food, treats and cocktails, six teams entered in a fierce battle for first place in the highly anticipated Games.
Event One was a Pseudoscience Fair, in which teams created scientific posters to prove unscientific concepts, including birthday astrology, phrenology and crystal healing. Some teams conducted live “experiments” or used sweets, props and pandering to win over the judges.
Event Two required each team member to taste and name one of Bertie Bott’s Every Flavor Beans (a mainstay of the Harry Potter universe). Participants correctly identitifed a range of bean flavors, including everything from candyfloss and cinnamon to soap, earwax and vomit.
For Event Three, each team used a variety of building materials (including tinker toys, pipe cleaners, egg cartons and cardboard) to construct a scene related to the institute. Several teams crafted versions of the INI’s 7T MRI scanner. Teams also earned bonus points for wearing nametags adorned with photos of themselves dating back more than 10 years.
The judges deliberated carefully and ultimately named Carinna, Avnish, Jeana, Zach and Kaelan winners for their superb presentation on “The Effects of Phrenology on Collaborative Efforts in a Neuroscience Environment” and their outstanding jelly-bean tasting and construction skills.

Not long after moving to southern California to start his postdoc with Hongwei Dong, Mike Bienkowski found himself at a meeting listening to neuroscientists debate the divisions of the hippocampus.
Currently, three institutions in the U.S. have begun using 7-tesla magnets for clinical applications, but mostly for neurological and musculoskeletal conditions. The challenge now is showing how much more 7-tesla MRI can contribute to patient care.
Paul Thompson and his team just launched the ENIGMA World Aging Center, which will use the consortium’s network and a $682,000 grant from the National Institute on Aging to perform a global study of brain aging. The collaboration will help pinpoint the factors that contribute to healthy aging versus those that increase our risk for Alzheimer’s or Parkinson’s disease.
On October 24, the ultra-high-field 7T Terra magnetic resonance imaging (MRI) scanner at the USC Mark and Mary Stevens Neuroimaging and Informatics Institute (INI) of the Keck School of Medicine of USC received FDA approval for clinical use, opening up new avenues of care for patients with Alzheimer’s disease, multiple sclerosis and other diseases that affect the brain.
Now, the first neuronal-connectivity study to zoom in to the cellular level reports that the mouse hippocampus can in fact be divided into 22 discrete subregions. To find them, researchers led by Michael Bienkowski and Hong-Wei Dong at the University of Southern California, Los Angeles, compared gene expression and connectivity cell by cell.
The Virtual Brain Segmenter (VBS), a virtual reality tool for processing brain scan images, has been named a finalist for the 2018 Auggie Breakthrough Awards, which honor innovative academic-industry collaborations in virtual and augmented reality.
VBS was developed by INI’s Dominique Duncan, PhD, Tyler Ard, PhD, Arthur W. Toga, PhD and the industry group RareFaction Interactive to transform a tedious step in the scientific process into an immersive experience. After collecting MRI data, researchers typically correct errors in scan images by hand, but VBS allows them to speed up the process with a VR headset, joystick and larger-than-life images of the brain.
In an experimental trial, published in the Journal of Digital Imaging in July, participants finished a correction task 68 seconds faster using VBS compared with the traditional method, a highly significant time savings considering the task rarely took more than three minutes to complete.
Now, Dr. Duncan is traveling in Munich, Germany to represent INI at the Auggie Breakthrough Awards ceremony, where winners will be chosen in several categories, including Most Innovative Breakthrough, Most Impactful Breakthrough and Best in Show. Fellow finalists include representatives from NASA’s Jet Propulsion Laboratory, Stanford, the Mayo Clinic and international collaborators from Finland, Australia and beyond. Projects span the health sciences, communications, education, resource management and gaming.

In fiscal year 2017-2018, the USC Mark and Mary Stevens Neuroimaging and Informatics Institute (INI) at the Keck School of Medicine of USC received more than $30.5 million in active research funding.
A new preprint called “A systematic bias in DTI findings” could prove worrying for many neuroscientists. In the article, authors Farshid Sepehrband and colleagues of the University of Southern California argue that commonly-used measures of the brain’s white matter integrity may be flawed.
Earlier this month, six undergraduate students from California State University, Fullerton presented their summer research results to a room full of neuroscientists at the Mary and Mark Stevens Neuroimaging and Informatics Institute (INI). The collaboration is part of CSUF’s Big Data Discovery and Diversity through Research Education Advancement and Partnerships (BD3 REAP) program, which trains underrepresented students in big data science.
“The program exposes these young investigators to what modern science is about these days, which is the collection of ever larger data sets,” said Jack Van Horn, INI’s director of education and leader of the collaboration. “They’re learning about the challenges of big data, and how they can manage, model, and understand it.”
Building on several semesters studying data science and analytics at CSUF, each student selected a big data neuroimaging project to pursue this summer with the guidance of INI faculty members and postdoctoral researchers.
For their presentations, the students covered methods, results and next steps. Each created a slideshow and was encouraged to delve into the technical aspects of research performed. Focus areas included the Epilepsy Bioinformatics Study for Antiepileptogenic Therapy (EpiBioS4Rx), using gene expression to build an atlas of the hippocampus and the link between functional brain connectivity and familial Alzheimer’s disease.
The students received mentorship from INI faculty, including program director Jack Van Horn, Kay Jann, Tyler Ard, Dominique Duncan, Lirong Yan and Meredith Braskie.
“This has been a great opportunity for INI to expand its commitment to training the next generation of leaders,” said Arthur W. Toga, provost professor at USC and director of INI. “We were impressed by the students’ work and look forward to continuing our outreach efforts with CSU Fullerton.”

Two-thirds of AD patients are women, leading to the commonly held assumption that women run a higher risk of dementia. In Chicago, Arthur Toga of the University of Southern California, Los Angeles, challenged that view with data gleaned from a meta-analysis of 58,000 participants in 27 AD studies.
USC offers numerous institutional training opportunities for postdocs, including parallel lines of research on aging and Alzheimer’s disease. But the new project, “Training for the Multiscale and Multimodal Analysis of Biomarkers in Alzheimer’s Disease,” differs from a traditional postdoctoral fellowship in its highly collaborative nature and its emphasis on both the informatics behind Alzheimer’s research and the use of multiple methodologies to study the disease.

One of the largest-ever brain morphometry studies of autism, led by the Enhancing Neuro Imaging Genetics through Meta-Analysis autism spectrum disorders working group (ENIGMA-ASD), was published in the American Journal of Psychiatry in April.
Most 8-year olds care more about toys and video games than neuropsychology — but not Joy Stradford. She often went to work with her mother, a special education teacher in New Jersey, and was both concerned for and intrigued by the disabled children she met.
For years, the Mark and Mary Stevens Neuroimaging and Informatics Institute (INI) has been a key contributor to the Autism Center for Excellence (ACE) Network, which aims to advance autism research by studying brain structure and aggregating and sharing data. Jack Van Horn, associate professor of neurology at the Keck School of Medicine of USC, directs ACE’s coordinating center.
Van Horn, along with INI’s Zachary Jacokes and Carinna Torgerson and Andrei Irimia of the USC Davis School of Gerontology, recently published an MRI study of the disorder in Nature Scientific Reports. The researchers studied brain structures of autism patients versus healthy individuals, comparing males and females; they found that sex differences in ASD appear to be linked to differences in white matter, specifically in parts of the temporal and parietal lobes. The results are an important step toward understanding why ASD is almost four times more common in boys than girls.
Now, INI researchers are also one step closer to understanding how autism affects the human brain across the lifespan. This month, one of the largest-ever brain morphometry studies of autism, led by the Enhancing Neuro Imaging Genetics through Meta-Analysis autism spectrum disorders working group (ENIGMA-ASD), was published in the American Journal of Psychiatry.
INI’s Paul M. Thompson, director of the Imaging Genetics Center and principal investigator of ENIGMA, and Neda Jahanshad, assistant professor of neurology, contributed to the study.
“Autism is hard to treat because we lack a deep understanding of how children with autism develop differently, and how best to nurture their brain development,” said Thompson.
“With our global alliance—now studying thousands of children across the world—we are starting to see distinctive brain features in children with autism, and learn how the brain adapts throughout life; we are beginning to have the power to rigorously test and verify factors that may be beneficial for different children.”
The study analyzed MRI scans to identify differences in cortical and subcortical structures between 1,571 patients with ASD and 1,651 healthy controls. Participants from 49 different imaging centers, aged 2 to 64, were included in the analysis. Researchers examined differences in subcortical volumes, cortical thickness and surface area.
ASD subjects had smaller volumes in several brain structures, including the pallidum, putamen, amygdala and nucleus accumbens; they also had decreased cortical thickness in the temporal cortex and increased thickness in the frontal cortex. Cortical development appeared to be most impacted during adolescence, when large differences in thickness were observed. The analysis has led to the first definitive maps of the affected brain regions.
The ENIGMA consortium performs some of the largest neuroimaging studies of rare genetic diseases and psychiatric disorders such as schizophrenia and bipolar disorder, focusing on the interaction between brain health and genetics. The group currently investigates 22 diseases, with researchers in 37 countries analyzing data from more than 53,000 subjects.

A large number of people taking medications for Alzheimer's actually might not have the disease, according to early evidence from a study presented Wednesday. But detection may become easier if an experimental blood test ultimately proves accurate, said another report released on the same day.
Elegant visualizations of neuroscience data and phenomena are meant to help researchers better understand the brain, but these eye-catching images also have artistic value. This quarter, two of the USC Mark and Mary Stevens Neuroimaging and Informatics Instituteâ€™s (INI) visualization specialists, Jim Stanis and Tyler Ard, contributed images to an on-campus exhibition, Neurological System Art.
Stanis, INIâ€™s in-house medical and scientific animator, created â€œSynaptogenesis,â€ an image that shows neurons in the brain forming new connections: axons of each neuron grow to synapse with the dendritic spines on the dendrites of other neurons. Stanis used 3DS Maxâ€”an animation software package originally built to create visual effects for TV and filmâ€”to create 3D models of neurons and to animate the growth of dendrites and axons.
Ard, assistant professor of research at INI, created â€œConnected Selfâ€ using data from fellow INI assistant professor Yonggang Shi. The image shows two different MRI scans of the same subject, highlighting the axons that connect various parts of the brain to one another. Connectivity was measured with a technique called diffusion MRI tractography; different colors represent the orientation of axons in the brain.
Their work appears alongside two featured artists: J. Frederic May and Jane Szabo. In 2012, May suffered a severe stroke during open heart surgery, leaving him legally blind and experiencing visual hallucinations. He uses a data corruption software to create blurry and fragmented images that simulate his visual experience. Szabo has prosopagnosia, or face blindness, and explores self-portraiture and identity through her work. She received her MFA from the Art Center College of Design in Pasadena.
The exhibit is currently on display at the Hoyt Gallery in the Keith Administration Building (KAM).
Keck School of Medicine of USC surgeon and radiologist team up to test a new ultrahigh field imaging technology
USC Mark and Mary Stevens Neuroimaging and Informatics Institute (INI) researchers have used machine learning to determine key sex differences in Magnetic Resonance Imaging data in a new study published online ahead of print in NeuroImage. Part of INI's Big Data for Discovery Science initiative, the study analyzed brain scans of more than 1500 healthy youths.
Researchers found that cortical thickness in two areas of the brain-the middle occipital lobes and the angular gyri-are major predictors of sex. Specifically, females demonstrate significantly thicker gray matter in these areas when multiple regions were included in the sex difference model. The team also developed a statistical learning model that accurately predicted sex based on brain morphology in more than 80 percent of participants.
"If we can establish a better understanding of sex differences in the brain, we'll be one step closer to personalized medicine," says Farshid Sepehrband, PhD, project specialist at INI and lead author of the paper. "Once we have a baseline of neuroanatomical sex differences, we can start to explore how and why some diseases-for example, autism-manifest differently in boys and girls." Understanding the anatomic differences between male and female brains could help doctors better diagnose and treat autism in the future.
The study was a collaborative effort among USC researchers, including INI's Sepehrband, Kirsten Lynch, Ryan Cabeen, Lu Zhao, Kristi Clark and Arthur W. Toga. USC faculty from the Viterbi School of Engineering's Information Sciences Institute and the Keck School of Medicine of USC's departments of pediatrics and preventive medicine also contributed to the research, along with Ivo Dinov, PhD, of the University of Michigan.
The code from the study is open-source and public via Github, where users can generate the same figures published in the paper. Sepehrband also used Plotly to generate an interactive plot of the results: hover over each plot point to see the sex difference statistics.

The human brain contains distinct geographic regions that communicate throughout the day to process information, such as remembering a neighborâ€™s name or deciding which road to take to work. Key to such processing is a vast network of densely bundled nerve fibers called tracts. Itâ€™s estimated that there are thousands of these tracts, and, because the human brain is so tightly packed with cells, they often travel winding, contorted paths to form their critical connections. That situation has previously been difficult for researchers to image three-dimensional tracts in the brain of a living person.

Medical Theory has come up a long way to curing people from several diseases. With the help of numerous researches and theories, the hypothesis of medical is kept on being more fruitful over time. However, all the studies and tests havenâ€™t yet discovered all the conditions related to psychiatric and neurological issues. The issues of psychiatric and neurological imply to the mental health problems which can top a cluster of disorders, including mental, personality, behaviour, and social interactions. Like physical disorders, psychiatric and neurological issues are a little bit tricky to diagnose precisely, and hence overwhelmed the treatment and healing methods.

The USC Mark and Mary Stevens Neuroimaging and Informatics Institute will bring together scientists from around the world to further understanding of the brain. Longtime benefactors Mark and Mary Stevensâ€™ $50 million gift will accelerate the instituteâ€™s already dramatic progress toward mapping the healthy brain and illuminating neurologic diseases such as Alzheimerâ€™s and schizophrenia.
What would we be able to see, Toga pondered, if we could use computer-enabled imaging to view how the brain works? Toga has devoted his career to answering that question. As director of the USC Mark and Mary Stevens Neuroimaging and Informatics Institute, he has built one of the largest data collections of human brain images in the world. By combining the power of computer science with the study of brain science, his team at the instituteâ€”which comprises researchers across disciplines like neuroscience, physics, engineering and mathâ€”can map brain image data in an unprecedented way.
