From: Morphine modulation of pain processing in medial and lateral pain pathways
Effects of morphine on the temporal distribution of discriminant capability of neural ensembles in ACC, MD, SI and VPL. The correct percentage of neural ensembles to differentiate three types of sensory inputs was compared before and after morphine injection. As can be seen, the ability of neural ensembles to discriminate pain from non-pain stimuli significantly decreased after morphine administration. The markers along the x-axis indicate the statistically significant difference in disciminant performance before (solid lines) and after (dashed lines) injection of morphine.
