liikeärsykkeet
Liikeärsykkeet, also known as motor evoked potentials (MEPs), are a neurophysiological technique used to assess the integrity of the motor pathways in the nervous system. This method involves stimulating the motor cortex, typically using transcranial magnetic stimulation (TMS) or direct electrical stimulation, and then recording the resulting electrical activity in the muscles. The recorded signals, the MEPs, provide information about how efficiently and effectively the neural impulses travel from the brain down to the muscles.
The procedure for eliciting and measuring MEPs is relatively straightforward. A TMS coil is placed on the
The characteristics of the recorded MEP, such as its amplitude, latency (the time it takes to appear),
