Auditory Task Clinical Trial
Official title:
Measuring the Stimulated Brain: Determining the Specificity of High Definition Electrical Brain Stimulation Using Simultaneous Magnetoencephalography
Non-invasive human brain stimulation using weak transcranial direct‐current stimulation
(tDCS) has been thousands of times in research studies over the past fifteen years as a
therapy to help improve the effectiveness of repeated training sessions (e.g., hand
exercises in the context of daily physiotherapy), due to its safety, tolerability,
convenience and cost‐effectiveness. tDCS works by temporarily enhancing brain activity
during performance of a specific task, helping with learning and training.
The investigators will use magnetoencephalography (MEG) brain imaging to view the real‐time
effects of high definition (HD) tDCS on several brain areas involved in vision, hearing,
movement, and memory. The investigators hypothesize that changing the task (auditory, visual
or memory task) but keeping the position of the electrodes over the motor cortex will result
in modulation of brain activity in only the central target motor area, and not on non-target
temporal, occipital or pre-frontal areas.
