Involvement of dopamine D1 receptors of the hippocampal dentate gyrus in spatial learning and memory deficits in a rat model of vascular dementia

P Wan et al. Pharmazie. 2014 Sep.

Abstract

We investigated the involvement of dopamine (DA) and its D1 receptors of the hippocampal dentate gyrus (DG) in spatial learning and memory deficits in a rat model of vascular dementia (VD) established by permanent bilateral carotid occlusion. Spatial learning and memory abilities of rats were measured by Morris water maze, and extracellular concentrations of DA in the DG were determined by in vivo microdialysis. The DA concentrations in the DG decreased in the VD rats compared with sham-operated group. Microinjection of SFK38393 (D1 receptor agonist) into the DG attenuates spatial learning and memory deficits in the VD rats.
