Owing to their intimate anatomical relationship with cerebral arterioles, astrocytes have been postulated as signal transducers, transferring information from activated neurones to the cerebral microcirculation. These forwarded signals may involve the release of vasoactive factors from the end-feet of astrocytes. This mechanism is termed 'neurovascular coupling' and its anatomical components (i.e. neurone, astrocyte and vascular cells) are termed the 'neurovascular unit'. The process of… CONTINUE READING
