Disrupted population coding in the prefrontal cortex underlies pain aversion

A Li, Y Liu, Q Zhang, I Friesner, HJ Jee, ZS Chen… - Cell reports, 2021 - cell.com
The prefrontal cortex (PFC) regulates a wide range of sensory experiences. Chronic pain is
known to impair normal neural response, leading to enhanced aversion. However, it …

Scaling up cortical control inhibits pain

J Dale, H Zhou, Q Zhang, E Martinez, S Hu, K Liu… - Cell reports, 2018 - cell.com
Acute pain evokes protective neural and behavioral responses. Chronic pain, however,
disrupts normal nociceptive processing. The prefrontal cortex (PFC) is known to exert top …

Altered excitability and local connectivity of mPFC-PAG neurons in a mouse model of neuropathic pain

J Cheriyan, PL Sheets - Journal of Neuroscience, 2018 - Soc Neuroscience
The medial prefrontal cortex (mPFC) plays a major role in both sensory and affective aspects
of pain. There is extensive evidence that chronic pain produces functional changes within …
