Evoked Potentials Part I: Exogenous or Stimulus-related Evoked Potentials

Thursday, October 20, 2022

On-Demand Playback


Join BIOPAC for our Evoked Potentials Demonstration!

Each day, our brains are bombarded with a myriad of internal and external stimuli. Our response to such stimuli can easily be recorded using averaged evoked potentials (EP) to provide a wealth of information about our psychophysiological states. Short-latency evoked potentials (BAEP, VEP, SEP) are obligate neuronal responses to stimuli that can even be recorded during sleep. These EPs reflect the processing of stimuli by primary sensory pathways.

Learn how to use AcqKnowledge to stimulate a range of senses using electrical, auditory, visual, haptic, scent, and thermal stimuli and record evoked potentials. We will also demonstrate how stimuli can be synched with physiological recordings via tools such as E-Prime, SuperLab, DirectRT, MediaLab, Inquisit, Vizard, and Presentation.

What You Will Learn:

  • Introduction to EPs
  • Theory and guidelines
  • How to record great EP data
  • How to record exogenous EPs (BAEP, VEP, SEP)
  • How to prepare data for analysis
  • Analysis automation
