Multi-atlas thalamic nuclei segmentation on standard T1-weighed MRI with application to normal aging
The threefold aims of this study were to validate the use of a modified thalamic nuclei segmentation method on standard T1 MRI data, to apply this method to quantify age-related volume declines, and to test functional meaningfulness by predicting performance on motor testing.

A prospective study revealing a compounded burden of COVID-19, sex, and clinical diagnosis of alcohol use disorder and HIV infection on quality of life, anxiety, and alcohol use
Participants were drawn from our ongoing longitudinal studies of people with HIV infection, alcohol use disorder (AUD), HIV + AUD comorbidity, and controls.

Postural instability in HIV infection: relation to central and peripheral nervous system markers
Our objective is to determine the independent contributions of central nervous system (CNS) and peripheral nervous system (PNS) metrics to balance instability in people with HIV (PWH) compared with people without HIV (PWoH).

Prior test experience confounds longitudinal tracking of adolescent cognitive and motor development
We measured change in cognitive and motor abilities over four test sessions in participants from the National Consortium on Alcohol and NeuroDevelopment in Adolescence study.

Poor subjective sleep predicts compromised quality of life but not cognitive impairment in abstinent individuals with Alcohol Use Disorder
The Pittsburgh Sleep Quality Index (PSQI) was used to evaluate subjective sleep in 90 individuals with AUD sober for an average of 3 months and in 50 healthy controls.

Alcohol’s effects on the mouse brain are modulated by age and sex
To test the hypothesis that the effects of binge alcohol exposure on developmental brain growth trajectories are influenced by age of exposure and sex, adolescent and adult mice were exposed to a binge-like ethanol exposure paradigm.

Adolescent Binge Drinking Is Associated With Accelerated Decline of Gray Matter Volume
The impact of binge drinking on gray matter volume (GMV) development was examined using 5 waves of longitudinal data from the National Consortium on Alcohol and NeuroDevelopment in Adolescence study.

Disruption of cerebellar-cortical functional connectivity predicts balance instability in alcohol use disorder
Whether disruption of neural communication between cerebellar and cortical brain regions exerts an influence on ataxia in alcohol use disorder (AUD) was the focus of this study.

Systemic Administration of the TLR7/8 Agonist Resiquimod (R848) to Mice Is Associated with Transient, In Vivo-Detectable Brain Swelling
Here, resiquimod (R848) was administered to mice to stimulate peripheral immune activation, and the effects on brain volumes and neurometabolites determined.

Growth trajectories of cognitive and motor control in adolescence: How much is development and how much is practice?
Executive control continues to develop throughout adolescence and is vulnerable to alcohol use. Although longitudinal assessment is ideal for tracking executive function development and onset of alcohol use, prior testing experience must be distinguished from developmental trajectories.

Aging Accelerates Postural Instability in HIV Infection: Contributing Sensory Biomarkers
Whether aging with HIV accelerates age-related liability for postural instability and what sensory factors contribute to imbalance were examined in 227 PWH and 137 people living without HIV (PWoH), age 25 to 75 years.

Neurobiology of Alcohol Dependence: Focus on Motivational Mechanisms
Recent research focusing on brain arousal, reward, and stress systems is accelerating our understanding of the components of alcohol dependence and contributing to the development of new treatment strategies.
