Evoked Potentials Part II: Event-related or Endogenous Evoked Potentials (ERP)

Thursday, January 19, 2023



Event-related or Endogenous Evoked Potentials (ERP) training

Our brains are constantly reacting to sensory, cognitive, or motor events and ERPs help us understand our response to a stimulus. ERPs are often recorded during a selective attention task like an oddball paradigm. Based on top-down expectancies and bottom-up stimulus inputs, one pays attention to relevant stimulus and ignores the irrelevant stimulus. The waveforms thus obtained reflect the higher processing of the relevant/ target stimuli.

Join BIOPAC to learn how to measure ERPs and fNIRS response to an oddball paradigm task (P300) in both the real and virtual world. We’ll present a very easy and powerful approach to record and analyze neurovascular response to the ERP paradigm. BIOPAC’s AcqKnowledge software includes a fully automated event-driven data reduction program for ERPs and BIOPAC’s Stimulus Presentation application. The software allows the user to pick a time window around the stimulus event for measuring the data. The off-line averaging function in AcqKnowledge displays the averaged response to each different stimulus triggered by Stimulus Presentation. Also learn how to fully automate event-driven data reduction for ERPs and other stimulus-response (S-R) applications with AcqKnowledge software.

You Will Learn the Following:

  • Introduction to ERPs
  • Theory and guidelines for recording ERPs
  • How to record great ERP data
  • How to use the Stimulus Presentation functionality in AcqKnowledge to create stimulus delivery paradigms
  • How to record ERP-fNIRS response to oddball paradigm task (P300) in the real or virtual world
  • How to prepare data for analysis
  • Workflow Automation Tools
