Janus effect of the anterior cingulate cortex: Pain and emotion
Over the past 20 years, clinical and preclinical studies point to the anterior cingulate cortex
(ACC) as a site of interest for several neurological and psychiatric conditions. The ACC …

Pros and cons of clinically relevant methods to assess pain in rodents
The primary objective of preclinical pain research is to improve the treatment of pain.
Decades of research using pain-evoked tests has revealed much about mechanisms but …

Oxytocin promotes prefrontal population activity via the PVN-PFC pathway to regulate pain
Neurons in the prefrontal cortex (PFC) can provide top-down regulation of sensory-affective
experiences such as pain. Bottom-up modulation of sensory coding in the PFC, however …

Map** cortical integration of sensory and affective pain pathways
Pain is an integrated sensory and affective experience. Cortical mechanisms of sensory and
affective integration, however, remain poorly defined. Here, we investigate the projection …

Neuropathic pain causes pyramidal neuronal hyperactivity in the anterior cingulate cortex
The anterior cingulate cortex (ACC) is thought to be important for acute pain perception as
well as the development of chronic pain after peripheral nerve injury. Nevertheless, how …
