Cognitive effects of theta frequency bilateral subthalamic nucleus stimulation in Parkinson’s disease: A pilot study

open access: yesBrain Stimulation, 2021
Background: There is significant evidence for cognitive decline following deep brain stimulation (DBS). Current stimulation paradigms utilize gamma frequency stimulation for optimal motor benefits; however, little has been done to optimize stimulation ...

Individual differences in neuroanatomy and neurophysiology predict effects of transcranial alternating current stimulation

open access: yesBrain Stimulation, 2021
Background: Noninvasive transcranial electrical stimulation (tES) research has been plagued with inconsistent effects. Recent work has suggested neuroanatomical and neurophysiological variability may alter tES efficacy.

The frequency-dependent stimulation effects of rTMS on the performance of problem-solving tasks and ongoing oscillations

open access: yesEuropean Psychiatry, 2022
Introduction Recent studies suggest that online repetitive transcranial magnetic stimulation (rTMS) can induce local entrainment of ongoing endogenous oscillatory activity that impacts cognitive performance, and the effect may depend on the function of ...
