What Does PPI Stand For?
PPI stands for Prepulse Inhibition
PPI, or Prepulse Inhibition, is a neurological phenomenon that refers to the reduction in the startle response when a weak prepulse stimulus precedes a stronger startling stimulus. This inhibitory mechanism is an important aspect of sensory processing and attentional control, and is commonly used in research to investigate various psychiatric and neurological disorders, highlighting deficits in sensory gating abilities.
