Stimulating the brain in the MEG Organizer : Jim

Entrained Brain Oscillations and the Processing of Complex Auditory or Visual Stimuli Neurostimulation techniques including transcranial current stimulation (either direct or alternating current (tDCS/tACS)) and deep brain stimulation (DBS) allow us to directly modulate the level and timing of spontaneous neuronal activity while also producing changes outlasting stimulation. Recent methodological advancements provide the unique opportunity to directly study the effects of neuromodulation on neuronal activity and the associated changes in behaviour and disease symptoms on the neurophysiogical level using MEG. However, this is complicated by magnetic artifacts orders of magnitudes larger than the brain signal of interest.
