We investigated the synaptic properties of the afferent sensory connection to neurons in the inferior salivatory nucleus (ISN) controlling the parotid and von Ebner salivary glands. Mean synaptic latency recorded from parotid gland neurons was significantly shorter than von Ebner gland neurons. Superfusion of GABA and glycine resulted in a concentration-dependent membrane hyperpolarization. Use of glutamate receptor antagonists indicated that both AMPA and N-methyl-d-aspartate (NMDA) receptors are involved in the evoked excitatory postsynaptic potentials (EPSPs). Inhibitory postsynaptic potential (IPSP) amplitude increased with higher intensity ST stimulation. Addition of the glycine antagonist strychnine did not affect the amplitude of the IPSPs significantly. The GABA<jats:sub>A<\/jats:sub> receptor antagonist, bicuculline (BMI) or mixture of strychnine and BMI abolished the IPSPs in all neurons. IPSP latency was longer than EPSP latency, suggesting that more than one synapse is involved in the inhibitory pathway. Results show that ISN neurons receive both excitatory and inhibitory afferent input mediated by glutamate and GABA respectively. The ISN neuron response to glycine probably derives from descending connections. Difference in the synaptic characteristics of ISN neurons controlling the parotid and von Ebner glands may relate to the different function of these two glands. <\/jats:p>","DOI":"10.1152\/jn.01115.2007","type":"journal-article","created":{"date-parts":[[2008,1,17]],"date-time":"2008-01-17T01:45:48Z","timestamp":1200534348000},"page":"1267-1273","source":"Crossref","is-referenced-by-count":14,"title":["Synaptic Responses of Neurons Controlling the Parotid and von Ebner Salivary Glands in Rats to Stimulation of the Solitary Nucleus and Tract"],"prefix":"10.1152","volume":"99","author":[{"given":"Takeshi","family":"Suwabe","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hideyuki","family":"Fukami","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Robert M.","family":"Bradley","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"24","reference":[{"key":"R1","doi-asserted-by":"publisher","DOI":"10.1002\/syn.890030406"},{"key":"R2","doi-asserted-by":"publisher","DOI":"10.1016\/0010-406X(69)90571-4"},{"key":"R3","doi-asserted-by":"publisher","DOI":"10.1113\/jphysiol.2007.132365"},{"key":"R4","doi-asserted-by":"crossref","unstructured":"Baptista V, Varanda WA.
