P300 ( Cognitive evoked potentials) in Tiznit

Neurologist

It is used in psychiatry. The P300 wave is a positive wave that occurs when a subject senses an expected and unpredictable stimulus. It represents a modification of the activation of neural networks in relation to a cognitive operation. The latency of this wave gives an indirect indication of the duration of cognitive operations, and its amplitude provides an index of the energetic aspect of cognitive processes.
