Increase in nociceptive reflex receptive field size during periods of threat

Takeaway

  • Threat can amplify pain and spinal nociception, as measured by increases in reflex receptive field (RRF) size.

Why this matters

    This study identified that periods of threat can result in the enlargement of RRFs, and may help clarify the mechanism(s) underlying emotional modulation of spinal nociception.
