hunger
Etiology:
- hypoglycemia
Comparative biology:
- hunger attenuates behavioral responses & affective properties of inflammatory pain without altering acute nociceptive responses [1]
- activity in hunger-sensitive agouti-related protein (AgRP)-expressing neurons abrogates inflammatory pain
- neural processing of hunger & inflammatory pain converge in the hindbrain parabrachial nucleus
- anti-nociceptive effect of hunger is mediated by neuropeptide Y (NPY) signaling in the parabrachial nucleus [1]
