Excitatory and inhibitory effects of serotonin on sensorimotor reactivity measured with acoustic startle

M Davis, DI Strachan, and E Kass

Serotonin infused into the lateral ventricle in rats produced a dose-dependent depression of the acoustic startle reflex. When infused onto the spinal cord, serotonin produced a dose-dependent increase in startle. Thus the same neurotransmitter can modulate the same behavior in opposite ways, depending on which part of the central nervous system is involved.
