Abstract
Parkinson disease (PD) is a common neurodegenerative condition. It affects the central nervous system, and it impairs cognitive processes, motor skills and other functions. The aim of this study was to determine the synaptic processes in medial Entorhinal cortex (mENT) under High frequency stimulation of Basolateral Amygdala on the model of Parkinson's disease under the influence of Hydrocortisone. Rotenone is involved in the degeneration of dopaminergic neurons. We investigated whether hydrocortison protects against rotenone-induced dopaminergic neurotoxicity in a rat model by in vivo electrical recording from medial Entorhinal cortex. Hydrocortison significantly improved electrical activity of neurons in the mENT of rotenone-induced PD model rats.
