Resting-State EEG Aperiodic Exponent Moderates the Association Between Age and Memory Performance in Older Adults

This study finds that the aperiodic exponent in resting-state EEG moderates age-related memory decline in older adults, with higher exponents associated with better memory performance.

Relationships between GABA+ and Glx concentrations with age and inhibition in healthy older adults

This study examines age-related changes in GABA+ and Glx concentrations and their associations with inhibition tasks in healthy older adults, finding no significant age-related changes but a significant negative relationship between SM1 Glx and go/no-go error rates.

Neurophysiological Correlates of Modifiable Dementia Risk Factors in Cognitively Unimpaired Older Adults

This study identifies neurochemical markers in specific brain regions associated with modifiable dementia risk factors in cognitively unimpaired older adults.

Age-related Inhibitory Decline: Examining Inhibition Sub-Components and their Impact on Sustained Attention in Healthy Ageing

This study examines age-related changes in inhibitory sub-components and their impact on sustained attention in healthy older adults, finding specific age effects and mediation effects.

Baclofen, a GABAB receptor agonist, impairs motor learning in healthy people and changes inhibitory dynamics in motor areas

This study shows baclofen, a GABAB receptor agonist, impairs motor learning and reduces expected decreases in GABA levels during motor learning.

Sustained activation in basal ganglia and cerebellum after repetitive movement in cervical dystonia

This paper investigates sustained fMRI BOLD signals in cervical dystonia patients after repetitive movement, finding abnormal activity in the putamen and cerebellum, and links these findings to cervical muscle function via sEMG.

Repeated unilateral handgrip contractions alter functional connectivity and improve contralateral limb response times: A neuroimaging study

This study shows that repeated unilateral handgrip contractions at 50% MVC improve contralateral hand response times and alter functional connectivity and neurochemical levels in sensorimotor areas.

GABA relates to functional connectivity changes and retention in visuomotor adaptation

The paper investigates how GABA levels and functional connectivity in M1 and cerebellum relate to retention of visuomotor adaptation.
