Time-Dependent Facilitation of Homologous Actions

This study investigates how effector homology and temporal delays influence interference and facilitation between unimanual actions, revealing a time-dependent shift from interference to facilitation specific to homologous actions.

Bilateral Intracortical Inhibition during Unilateral Motor Preparation and Sequence Learning

This study investigates how sequence learning affects bilateral intracortical inhibition during motor preparation, finding that it alters baseline inhibition levels rather than the acute inhibition decreases during preparation.

Sub-Concussive Head Impacts From Heading Footballs Do Not Acutely Alter Brain Excitability As Compared to a Control Group

This study investigates whether sub-concussive head impacts from football headings alter brain excitability, finding no acute changes in corticomotor inhibition compared to a control group.

The Neurochemical Mechanisms Underlying the Enhancing Effects of Rewards and Punishments on Motor Performance

This study investigates how rewards and punishments affect motor performance by examining changes in glutamatergic facilitation and GABAA inhibition in the motor cortex during movement preparation.

Exploring Stop Signal Reaction Time Over Two Sessions of the Anticipatory Response Inhibition Task

This study examines SSRT changes across two sessions of the anticipatory response inhibition task and stop signal task, finding stable non-selective inhibition but changes in partial inhibition.

Cerebellar GABA change during visuomotor adaptation relates to adaptation performance and cerebellar network connectivity: A Magnetic Resonance Spectroscopic Imaging study.

This study uses MRSI to show GABA changes in the cerebellum during visuomotor adaptation correlate with performance and network connectivity.

Timing is everything: event-related transcranial direct current stimulation improves motor adaptation

This study applies event-related TDCS during motor adaptation tasks to investigate temporal specificity, finding cerebellar stimulation enhances movement-specific learning while M1 stimulation does not.

Residual errors in visuomotor adaptation persist despite extended motor preparation periods

The paper investigates how extended motor preparation time affects residual errors in visuomotor adaptation and finds that even with longer preparation, errors persist.

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.

Impaired Desynchronization of Beta Activity Underlies Memory Deficits in People with Parkinson’s Disease

This study shows that reduced beta desynchronization in Parkinson’s disease is linked to impaired memory formation.
