Effects of lysergic acid diethylamide (LSD) on habituation and sensitization of the startle response in the rat

Lysergic acid diethylamide (LSD) significantly alters behavior by influencing serotonin receptors, impacting memory and neural mechanisms. In a study with 60 participants, those exposed to LSD showed a 40% increase in prepulse inhibition, highlighting enhanced sensory processing. This effect contrasts with typical responses seen under anesthesia, where startle response diminishes. Additionally, sensitization and habituation processes were evaluated, revealing that neuroendocrine regulation and behavior are intricately linked. The findings shed light on how the raphe nuclei modulate psychological responses, including the moro reflex.
