PPI meaning in Medical ?

Answer:

What is Prepulse Inhibition mean?

Prepulse inhibition (PPI) is a neurological phenomenon in which a weaker prestimulus (prepulse) inhibits the reaction of an organism to a subsequent strong reflex-eliciting stimulus (pulse), often using the startle reflex. The stimuli are usually acoustic, but tactile stimuli (e.g. via air puffs onto the skin) and light stimuli are also used. When prepulse inhibition is high, the corresponding one-time startle response is reduced.

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. PPI is detected in numerous species including mice and humans. Although the extent of the adaptation affects numerous systems, the most comfortable to measure are the muscular reactions, which are normally diminished as a result of the nervous inhibition.

Deficits of prepulse inhibition manifest in the inability to filter out the unnecessary information; they have been linked to abnormalities of sensorimotor gating. Such deficits are noted in patients suffering from illnesses like schizophrenia and Alzheimer's disease, and in people under the influence of drugs, surgical manipulations, or mutations. Human studies of PPI have been summarised in reviews by Braff et al. (2001) and Swerdlow et al. (2008).
