What is macroelectrode

A conductive device that measures the electrical activity in a group of neurons. Macroelectrodes attached to the scalp transmit electrical signals and patterns from the brain during an electroencephalogram (EEG), for example. Neurosurgeons use macroelectrodes to help identify and stimulate (by sending a mild electrical current) regions of the brain during ablative surgery such as deep brain stimulation (DBS), pal-lidotomy or thalamotomy, procedures that insert stimulating electrodes into target areas of the brain create lesions (scar tissue) in the pallidum, or lesion the thalamus, respectively to disrupt neuron activity to lessen parkinsonian symptoms such as TREMORS, RIGIDITY, or BRADYKINESIA.
