Computer simulation of corticospinal activity during Transcranial Electrical Stimulation in neurosurgery.

Transcranial Electrical Stimulation (TES) is an important procedure in intraoperative motor monitoring. When neurosurgery is performed at certain difficult locations within the central nervous system (CNS), TES evaluates CNS functions during surgical manipulations to prevent post-operative complications. In TES, electrical stimulation is provided to the motor cortex through electrodes placed on the scalp, generating action potentials which travel through the nervous system.
