High-definition Transcranial Direct Current Stimulation (HD-tDCS) Verbal Learning

July 21, 2015 updated by: Melissa Pigot, The University of New South Wales

Enhancing Verbal Learning and Memory Using High-Definition Transcranial Direct Current Stimulation (HD-tDCS)

This project will use a new form of non-invasive brain stimulation called high-definition transcranial direct current stimulation (HD-tDCS) to facilitate verbal learning. This form of stimulation is similar to transcranial direct current stimulation (tDCS) but allows for more spatially focused stimulation. We hypothesise that HD-tDCS when applied to regions of the brain important for learning and memory will improve verbal learning and memory compared to sham HD-tDCS.
