Frontiers of BrainHealth

Don't miss the opening talk for the fall 2026 season of Frontiers of BrainHealth, our popular neuroscience lecture series, featuring cognitive neuroscientist Aron Barbey, PhD, director of the Notre Dame Human Neuroimaging Center, as he shares 
recent discoveries in network neuroscience that suggest intelligence emerges from a rich constellation of networks whose functions are orchestrated in a flexible, goal-directed manner. 

Advancing the Science and Engineering of Intelligence: From Network Neuroscience to Interventions for Precision Health 

UT Dallas researcher Chandramallika Basak, PhD, director of the Lifespan Neuroscience and Cognition (LiNC) Lab at the Center for Vital Longevity, shares insights into leading-edge controlled randomized trials (CRTs) conducted by her lab, focused on improving cognition in older adults. These studies identify moderators and mediators of cognitive training in both healthy aging and pre-clinical Alzheimer's disease (AD), as well as the game features of efficacious videogame training – insights that can guide design of best cognitive training for healthy aging and preclinical AD/early AD.

Millions of people experience concussions and other forms of brain injury each year and the impact on cognitive health can last a lifetime. UTSW Medical Center research leader Munro Cullum, PhD, shares emerging research on the connections between concussion, repetitive head trauma and the risk of developing dementia later in life, exploring diagnosis, prognosis, and long-term outcomes following brain injury, including concussion, repetitive head hits, and chronic traumatic encephalopathy (CTE).

Brain Injury and Risk of Dementia

If intelligence can increasingly be modeled, measured, and replicated, what remains distinctive about human beings? SMU Perkins School of Theology professor Robert Hunt, PhD, argues that the age of AI represents a “Copernican revolution” in our understanding of intelligence. Just as Copernicus removed humanity from the physical center of the universe, AI is removing humans from the intellectual center of the world they inhabit.

Dementia is one of the main culprits undermining what should be our most rewarding years. Most current dementia-prevention trials are labor-intensive and hence expensive and difficult to scale to the hundreds of millions who need it. Internationally recognized cognitive neuroscientist Ian Robertson, PhD, shares an inside look at The BrainHealth Project, and how the longitudinal study is measuring and targeting improvements in the brain health of 100,000 people over ten years using a telehealth, web-based interface and real-time remote coaching. 

Brainspan: How The BrainHealth Project Can Inform Dementia Prevention 

Millie Rincón-Cortés, PhD, leads the Developmental and Maternal Neurobiology Lab at UT Dallas, a developmental behavioral neuroscience lab that studies how exposure to adversity compromises behavioral and brain function throughout the lifespan. Her team is particularly interested in maternal adversity exposure because the postpartum period is a time of increased risk for affective dysregulation in women and because postpartum adversity is known to disrupt maternal behavior and have adverse consequences for offspring development.

Dr. Melissa Petersen's is assistant professor of Family Medicine and Osteopathic Manipulative Medicine at the Texas College of Osteopathic Medicine. Her research focuses on the utility of blood-based biomarkers in the detection of neurodegenerative disease states including Alzheimer's disease among different racial and ethnic groups. Her collaboration and work with the Health and Aging Brain Study- Health Disparities (HABS-HD) cohort allows access to a biologically well characterized sample of Non-Hispanic Whites, Black, and Hispanics ranging from age 30 and above with available MRI, PET (Amyloid, Tau), blood-based biomarkers and cognitive data.

Adolescence and young adulthood are critical developmental periods during which health-risk behaviors can emerge and become established, with important implications for long-term health and well-being. UT Arlington professors Melissa A. Lewis, PhD, and Dana M. Litt, PhD, discuss advances in digital technology that are transforming how researchers identify the cognitive, social and contextual mechanisms underlying these behaviors and how interventions are developed and delivered to reduce risk.

MRI Biomarkers for Vascular Cognitive Impairment and Dementia

Angela Shoup, PhD, executive director of the Callier Center for Communication Disorders, discusses how auditory access during infancy plays a vital role in shaping brain development and long-term cognitive functioning. Early and consistent exposure to sound supports the formation of neural pathways that enable speech perception, language growth, learning, and social emotional development. 

Strengthening Impact in Pediatric Hearing Health by Overcoming Barriers to Evidence-Based Care

NEW DATE: Computational psychiatry is reshaping our understanding of mental illness by integrating data-driven modeling with neurobiological insights. Andrew Michael, PhD, of Duke University examines the evolving role of brain imaging and AI in computational psychiatry, emphasizing their transformative promise, pitfalls, and path forward. 

From Data to Diagnosis: Computational Psychiatry and Brain Imaging in the Age of AI

Dr. Wig of UTD's Center for Vital Longevity describes how his lab uses network science to examine how these connections change across the adult lifespan, showing that alterations in brain network organization can predict future Alzheimer’s disease dementia beyond traditional biomarkers. 

It’s All About Your Connections: Rethinking Aging and Alzheimer’s Disease Through Brain Networks

Drug-associated memories can be a major driver of relapse in addiction. UTD neuroscience professor Dr. Andrew Eagle focuses on researching how the brain encodes and retrieves drug-cue memories that promote maladaptive behavior. He presents preliminary findings demonstrating that the entorhinal cortex (EC) plays a critical role in this process and explores the broader research goal of defining the neural mechanisms by which memory shapes motivation in addiction.

An Entorhinal Cortex Circuit in Cocaine Memories

Researchers have made great strides in understanding the biology of Alzheimer’s disease and learning how to detect and even treat it at the earliest stages when treatment may be most effective. Dr. Mary Sano, PhD, professor of psychiatry and the director of the Alzheimer's disease research at Mount Sinai School of Medicine, shares an update.

UTD neuroscience professor Puja K. Parekh, PhD, highlights recent work into how the brain processes information to inform goal-directed actions, decision-making and task disengagement, combining behavioral measurements with in vivo neurophysiological recordings to identify circuit mechanisms of effortful motivation and the effects of stress. The goal of these studies is to identify mechanisms to enhance therapeutic development for stress-related disorders.

Neural Substrates Underlying Effortful Behavior in Animal Models

Addiction remains a leading cause of preventable morbidity and mortality worldwide. In this talk, UT Southwestern's Hamed Ekhtiari, MD, PhD, builds on two decades of human neuroimaging, neuromodulation trials and biomarker development to review the scientific rationale for mechanism-informed brain stimulation approaches in addiction treatment.

UT Dallas Assistant Professor of Psychology Ryan Boyd, PhD, explores how everyday language — from tiny words like "the" and "me" to themes, narratives and expressions of self-belief — maps where attention is pointing. Highlighting recent studies, he shares how research into how communities adapt during turbulent periods and how shifts in language can foreshadow changes in well-being and mental health.
