CA1 hippocampal neuronal responses to curry leaves extract treatment in rats subjected to chronic cerebral hypoperfusion : a behavioral and histopathological study

Curry leaves VIZ. Murraya koenigii leaves (MKL) extract was found to possess robust antioxidant and anticholinesterase activities. Its memory enhancing effect in preclinical studies has also been reported in an animal model of drug induced amnesia. Alzheimer’s disease (AD) in its vascular hypothesis...
