Acute Stress Impairs Reversal Learning via Orbitofrontal Mechanisms
Key Highlights
Medicine · Neurology
This study demonstrates that acute stress impairs reversal learning in mice through specific neurochemical and transcriptional changes within the orbitofrontal cortex. The researchers identified altered dopamine signaling and gene expression patterns that correlate with the cognitive inflexibility observed after a stressful experience. For a neuroscientist developing preclinical models of pain and placebo analgesia, understanding how stress disrupts prefrontal-dependent cognitive flexibility is directly relevant to the mechanisms that may modulate pain perception and the efficacy of placebo interventions.
