Event-Related Potentials: N400 & P600

Event-Related Potentials: N400 & P600 12.04.2024

Event-related potential (ERP) is a measured brain response that is a direct result of a specific sensation, cognitive, or motor event.
More formally, it is any typical electrophysiological response to a stimulus. The video provides detailed insights into the components of N400 and P600.

N400 and P600 potentials are components of event-related potentials (ERPs) that arise in the brain in response to specific stimuli or events.
N400 is a negative ERP component typically associated with semantic processing and language comprehension. It occurs when the brain processes words or phrases and may indicate semantic incongruity or unexpectedness in context.

P600 is a positive ERP component that, among other things, is associated with syntactic and semantic processing in language.
P600 occurs during the processing of grammatical errors or unexpected elements in sentences.

The research and lecture are conducted by Patricia Ratmanova, Ph.D., a lecturer at the Department of Neural Activity at the Biological Faculty of Lomonosov Moscow State University.
The practical part of the video uses equipment, software, and accessories produced by us: MCScap and Neurovisor software.
