SmartEP P300/MMN

SmartEP – P300/MMN

Extends SmartEP with the acquisition of cognitive event-related potentials: P300 (conscious discrimination of deviant stimuli by the awake patient) and MMN (mismatch negativity, pre-attentive auditory discrimination).

Features

  • Definable frequent/deviant stimulus ratio (default 80 %/20 %)
  • The MMN response is determined by subtracting two waveforms
  • Special 50-50 sequence option for a non-random stimulus order (P300)
