| Research Abstract |
We studied the mechanism of hypertension in view of functional abnormality of the cardiovasucular center. Brainstem preparations with the vagus and glossopharyngeal nerves attached were dissected from E14-E16 control and spontaneous hypertensive rat (SHR) embryos. Neural responses to vagus or glossopharyngeal nerve stimulation were detected by means of multiple-site optical imaging. From the analysis of signal waveforms, we identified motor and sensory nuclei related to the vagus and glossopharyngeal nerves. In the nucleus of the tractus solitarius, developmental processes of the excitatory postsynaptic potential (EPSP) were similar between the control and SHR embryos.
