Abstract:Pain involves a multidimension network of brain circuits related to both somatosensation and cognitive-motivational dimension. Mouse fMRI allows for the in-vivo brain-wide functional mapping that can help explore the pain circuits at a systems level. We utilized transgenic mice in which we suppressed the anterior cingulate cortex (ACC) with optogenetics to better understand its role in pain. Our behavior and fMRI results show that the ACC is involved in the cognitive-motivational dimension of pain, but not in … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
