With the examination method "evoked potentials" we measure the excitation conduction in the course of an entire nerve tract up to the brain.
The results of this examination are important for diagnosing disorders in the course of nerve tracts, for example in acute and chronic diseases of the nerves, the spinal cord and the brain.
After around 20 or around 40 milliseconds, an electrical impulse on the arm or leg leads to a response from the brain cells responsible for perceiving sensitive impulses.
Patients are asked to relax. When stimulated, you will feel a slight, not uncomfortable, knocking.
