Glutamate in hypothalamic and limbic structures of diestrous, proestrous, ovariectomized and ovariectomized estrogen-treated rats.
Concentrations of glutamic acid were determined in the nucleus accumbens (ACB), medial preoptic area (MPO), anterior and posterior mediobasal hypothalamus (AMBH, PMBH) and mediocortical amygdala (AMY) of diestrous (D), proestrous (P), ovariectomized (OVX) and OVX rats treated with estradiol-benzoate (EB) 12 h and 24 h before decapitation. Significant changes of glutamate concentrations were found in the ACV and PMBH. Glutamate is reduced in OVX when compared to D, P and OVX-EB rats. No significant changes of glutamate concentrations could be detected in the MPO, AMBH, and AMY.
