These experiments examined the impact of extensive depletions of forebrain 5-hydroxytryptamine (5-HT; serotonin) levels on prepulse inhibition (PPI) of the acoustic startle reflex in rats. In ...
The acoustic startle response is an unconditional reflex manifested as a rapid contraction of facial and skeletal muscles in response to a sudden and intense startling stimulus. Translational research ...
The startle reflex is a rapid, involuntary response to sudden acoustic stimuli, and its study has provided valuable insights into the neural mechanisms underlying motor preparation. Research in this ...
