In Syrian hamsters, vasopressin (AVP) in the medial preoptic-anterior hypothalamus (MPOA-AH) controls a form of scent marking called flank marking. Another neurochemical signal that may interact with AVP to control flank marking is glutamate. We tested the hypothesis that glutamate
The behavioural and convulsant effects of imipenem (Imi), a carbapenem derivative, were studied after intraperitoneal (i.p.) or intracerebroventricular (i.c.v.) administration in DBA/2 mice, a strain genetically susceptible to sound-induced seizures. The anticonvulsant effects of some excitatory amino acid antagonists and
Bilateral infusion of DL-2-amino-5-phosphonovalerate (DL-APV) (which is a competitive antagonist for N-methyl-D-aspartate (NMDA) receptor) into the medial frontal cortex of conscious rats increased the amount of 3,4-dihydroxyphenylacetic acid (DOPAC) and the DOPAC/dopamine (DA) ratio in the cortical area. Moreover, intra-prefrontal

We studied isolated pontobulbospinal preparations from newborn rat brain. In the early postnatal period, the rostral part of the medial vestibular nucleus produces a potent inhibitory effect on neuronal structures of the bulbar respiratory center via the glutamatergic system. Microinjection
Because kainic acid (KA) is more potent than other excitatory amino acids (EAAs) in affecting synaptic transmission in the cochlear nucleus, previous reports have concluded that primary afferent neurotransmission to the cochlear nucleus in birds and mammals is mediated by
