Sensorimotor gating is a perceptual process aimed at filtering out irrelevant information. In humans and animal models, this function can be operationally measured through the prepulse inhibition (PPI) of the acoustic startle reflex. Notably, PPI deficits are associated with numerous neuropsychiatric conditions characterized by gating disturbances, including schizophrenia and Tourette syndrome. Ample evidence has shown that dopamine plays a key role in PPI regulation and, in particular, rodent studies indicate that this neurotransmitter modulates PPI through D1 and D2 dopamine receptors. In mice, the relative contributions of these two families of receptors are strain-dependent. Conversely, the role of D1 receptors in the regulation of PPI across different rat strains remains unclear.
