N200 wave

The N200 wave is a specific pattern seen in brain activity tests called event-related potentials (ERPs). It appears roughly 200 milliseconds after a person is presented with a stimulus, like a sound or a visual cue. The N200 is thought to be related to processes like recognizing, sorting, or paying attention to that stimulus. Its features can provide insights into how efficiently the brain processes information, and changes in its shape or timing can indicate differences in cognitive functions, such as attention or response inhibition.
