The lifespan trajectory of neural oscillatory activity in the motor system

open access: yesDevelopmental Cognitive Neuroscience, 2018
Numerous studies connect beta oscillations in the motor cortices to volitional movement, and beta is known to be aberrant in multiple movement disorders.

Response certainty during bimanual movements reduces gamma oscillations in primary motor cortex

open access: yesNeuroImage, 2021
Even when movement outputs are identical, the neural responses supporting them might differ substantially in order to adapt to changing environmental contexts.

Multi-spectral oscillatory dynamics serving directed and divided attention

open access: yesNeuroImage, 2020
Attention-related amplification of neural representations of external stimuli has been well documented in the visual domain, however, research concerning the oscillatory dynamics of such directed attention is relatively sparse in humans. Specifically, it

Children with cerebral palsy have altered oscillatory activity in the motor and visual cortices during a knee motor task

open access: yesNeuroImage: Clinical, 2017
The neuroimaging literature on cerebral palsy (CP) has predominantly focused on identifying structural aberrations within the white matter (e.g., fiber track integrity), with very few studies examining neural activity within the key networks that serve ...

Development and sex modulate visuospatial oscillatory dynamics in typically-developing children and adolescents

open access: yesNeuroImage, 2020
Visuospatial processing is a cognitive function that is critical to navigating one's surroundings and begins to develop during infancy. Extensive research has examined visuospatial processing in adults, but far less work has investigated how visuospatial

Aberrant oscillatory dynamics during somatosensory processing in HIV-infected adults

open access: yesNeuroImage: Clinical, 2018
While the arrival of combination antiretroviral therapy significantly decreased the prevalence of HIV-associated dementia, between 35 and 70% of all infected adults continue to develop some form of cognitive impairment.

Rich Club Characteristics of Alcohol-Naïve Functional Brain Networks Predict Future Drinking Phenotypes in Rhesus Macaques

open access: yesFrontiers in Behavioral Neuroscience, 2021
Purpose: A fundamental question for Alcohol use disorder (AUD) is how and when naïve brain networks are reorganized in response to alcohol consumption. The current study aimed to determine the progression of alcohol’s effect on functional brain networks ...
