Understanding the Role of the Ventrolateral Prefrontal Cortex in Emotional Memory using Transcranial Direct Current Stimulation and Transcranial Magnetic Stimulation
… using non-invasive brain stimulation techniques; transcranial direct current stimulation (tDCS) was used to increase cortical excitability of the VLFPC in Experiment 1 and transcranial magnetic stimulation (TMS) was used to inhibit the VLPFC in Experiment 2. Experiment 1 (Chapter 2) used tDCS to …

Multifocal Transcranial Direct Current Stimulation to Modulate Motor Learning
Transcranial direct current stimulation (tDCS) is a non-invasive brain stimulation technique that modulates neural excitability in targeted brain regions, influencing processes such as motor learning. While tDCS has been previously shown to benefit motor skill acquisition, much of this research has …
