摘要
Release of glutamate into the extracellular space of the cat nucleus tractus solitarii (NTS) was measured by in vivo microdialysis and high performance liquid chromatography. Perfusion of the probe with 100 mm potassium increased glutamate release by 21 1 % (P < 0.00 1), while electrical stimulation of the cervical vagus increased release by 53 % (P < 0.01). These results are compatible with the hypothesis that glutamate is a neurotransmitter released by vagal afferent nerve terminals in the NTS.
