Abstract:responsible for GABA synthesis, glutamate decarboxylase (GAD 65/67, P < 0.01), as well as the dendritic marker microtubule associated protein (MAP2, P < 0.05), and the dendritic spine marker spinophilin (P < 0.05) in the left NAcb core of HI rats compared with LI rats. There were no significant differences in any of these markers in the other brain regions investigated. We also identified a strong inverse relationship between impulsivity and the lower levels of GAD 65/67 (P < 0.01; r = -0.71) and MAP2 (P < 0.0… 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.
