In animals, including humans, the startle response is a largely unconscious defensive response to sudden or threatening stimuli, such as sudden noise or sharp movement, and is associated with negative effect. Usually the onset of the startle response is a startle reflex reaction, a brainstem reflectory reaction (reflex) that serves to protect vulnerable parts, such as the back of the neck (whole-body startle) and the eyes (eyeblink) and facilitates escape from sudden stimuli.

Prepulse Inhibition (PPI) is a neurological phenomenon in which a weaker prestimulus (prepulse) inhibits the reaction of an organism to a subsequent strong startling stimulus (pulse). The stimuli are usually acoustic, but tactile stimuli (e.g. via air puffs on the skin) and light stimuli are also used.
The reduction of the amplitude of startle reflects the ability of the nervous system to temporarily adapt to a strong sensory stimulus when a preceding weaker signal is given to warn the organism.

Deficits of prepulse inhibition, manifesting in the inability to filter out the unnecessary information, have been linked to abnormalities of sensorimotor gating, noted in patients suffering from illnesses like Schizophrenia and Alzheimer’s Disease, or under the influence of drugs, surgical manipulations, or mutations. Animal models are widely used to test hypotheses linking genetic components of various diseases with sensorimotor gating.
