Main brain regions that activate during a painful experience, highlighted as bilaterally active but with increased activation on the contralateral hemisphere (orange). Neuron  , DOI: ( /j.neuron ) Copyright © 2007 Elsevier Inc. Terms and Conditions

4 Figure 3 The Descending Pain Modulatory System
NCF (nucleus cuneiformis); PAG (periaqueductal gray); DLPT (dorsolateral pontine tegmentum); ACC (anterior cingulated cortex); +/− indicates both pro- and anti- nociceptive influences, respectively. Neuron  , DOI: ( /j.neuron ) Copyright © 2007 Elsevier Inc. Terms and Conditions
