Clinical Neuroscience and Development Laboratory

The CNDLAB variously focuses on research of several psychiatric disorders commonly seen in pediatric groups, including Attention-Deficit/Hyperactivity Disorder, Major Depressive Disorder, Conduct Disorder, and Autism Spectrum Disorders.

Current Research Projects

Biological Subtyping On Reward Task Data in ADHD

A five-year NIH study examining more than 400 ADHD and non-ADHD adolescents – the largest study of its kind! The goal of the study is to learn if ADHD is actually a collection of different biological subtypes that need different treatments. 

Changes in Brain Function through Repeated Emotion Regulation Training

This study examines the possibilities of the ways that learning how to regulate your emotions can change the very structure of your brain.

Executive Working Memory Training with ADHD Adolescents

This paid study uses safe, non-invasive functional Magnetic Resonance Imaging (fMRI) to explore whether an online executive working memory training program can effectively alter brain connectivity and clinically improve symptoms of ADHD. The goal is to determine whether this could become a new intervention for ADHD.

Past Research Projects

Most CNDLAB studies were made possible by extramural research grants from the National Institutes of Health and other funding agencies. The major grants that have supported CNDLAB research are described below.

Neural Mechanisms of a CBT Response in Compulsive Hoarding
This project tested the efficacy of a cognitive-behavioral therapy (CBT) for hoarding disorder (HD), and assessed changes in the brain as a result of this therapy. Brain imaging on 80 HD participants helped to identify changes in areas associated with cognitive and affective decision making. Researchers further aimed to identify neural biomarkers in HD that predict positive outcomes following CBT. 

Adolescent Maturation of Brain Network Integration for Executive Control Abilities
A large-scale project using fMRI to understand how executive control develops and to identify cognitive risk factors for psychiatric illness. Researchers studied the effects of working memory training on brain function for adolescents with ADHD by implementing an online program to train working memory (WM). fMRI data and neuropsychological tests revealed that working memory training increased WM performance, ADHD clinical functioning, and WM-related ADHD brain activity.

Characterizing Two Distinct ADHD Neurobiologies with fMRI
This study examined the neural and genetic differences between executive and motivational symptoms of ADHD. A total of 130 adolescents with ADHD and 130 healthy controls underwent psychiatric evaluation, neuropsychological testing, fMRI, and genetic sampling in order to uncover two different models of brain pathology in ADHD. Results suggest that ADHD is a collection of disorders that reach a similar symptom presentation through different neural pathways.

Neuroimaging Cognition in Adolescent Behavior Disorders
Using EEG, DTI, and fMRI, this project examined the traits and behaviors leading to disruptive behavior disorders (DBDs) in adolescents. Researchers aimed to identify the neural dysfunction that is specific to each adolescent DBD. This implies the comparison of abnormally functioning circuits that underlie different DBDs, different groups of symptoms, and different courses of development into adulthood. This approach led to the identification of abnormal cortical thickness and folding, which caused patterns of reduced gray matter in the brains of adolescents with conduct disorder. Furthermore, researchers linked ADHD symptom domains to specific neural pathways

Response Inhibition in Attention-Deficit/Hyperactivity Disorder
This study examined the effect of psychostimulants (ADHD drugs) that 18 teens used to alleviate symptoms associated with Attention-Deficit/Hyperactive Disorder (ADHD). Researchers used fMRI to understand how the brain changes after being dosed appropriately with ADHD medication for 1-2 years. Results suggest that ADHD medications may benefit patients by altering the frontoparietal brain networks underlying working memory.

Diffusion tensor magnetic resonance imaging correlates of cognitive and functional outcome after closed-head traumatic brain injury
This project examined the causal relationship between traumatic brain injury (TBI) and changes in the brain. Both MRI and neuropsychiatric testing data were compared between subjects with and without TBI. Abnormal functional connectivity was discovered in TBI patients in 12 distinct brain networks, paving the way for future studies of brain abnormality after TBI.
