WebMay 24, 2024 · July 29, 2024 — Researchers have shown how the amygdala, a brain region typically associated with fear, contributes to prepulse inhibition (PPI) by activating small inhibitory neurons in the ... WebSingle prolonged stress (SPS) has been used to examine mechanisms via which stress exposure leads to post-traumatic stress disorder symptoms. SPS induces fear extinction retention deficits, but neural circuits critical for mediating these deficits are unknown. To address this gap, we examined the effect of SPS on neural activity in brain regions …
