Endogenous Opioid and Cannabinoid Receptors are Involved in Antinociceptive Effects NSAIDS Injected into Anterior Cingulate Cortex of Rats

Abstract
Among several brain cortical areas the anterior cingulate cortex (ACC) is a key cortical region for pain perception. This structure is considered as a part of the neural pain matrix that is involved in emotional processing, cognitive-affective evaluation and reflected in pain unpleasantness ratings in human subjects. Anatomically, the ACC is a complex and heterogeneous cortex, receives afferent inputs mainly from the medial thalamic nuclei (midline and intralaminar nuclei) that contain nociceptive neurons that receive input from the spinothalamic tract [22]. Keywords - Niciception, Endegenic Cannabinoids,
