Neuronal messengers in the human cerebral circulation.

摘要: In recent years our knowledge of the nervous control cerebral circulation has increased. The use denervations and retrograde tracing in combination with immunohistochemical techniques demonstrated that vessels are supplied sympathetic, parasympathetic, sensory nerve fibers possibly central pathways containing a multiplicity new transmitter substances addition to classical transmitters. majority these transmitters neuropeptides. More recently it been suggested gaseous transmitter, nitric oxide (NO) also could participate neuronal regulation blood flow. Although little is known about physiological actions inter-relationships among all putative neurotransmitters, their presence within cerebrovascular will make necessary revise view on mechanisms neurotransmission.
