This study identifies age-related impairments in brain microvascular dynamics, particularly in precapillary sphincters, leading to reduced neurovascular function in aging.

The paper investigates how nitric oxide, endothelin-1, and KATP channels modulate brain pericyte function, vascular tone, and neurovascular coupling through distinct signaling pathways.

This study identifies precapillary sphincters as regulators of cerebral blood flow, showing their dilation and constriction in response to neural activity and ischemia.
