Projections from the anteroventral part of the medial amygdaloid nucleus in the rat
The medial amygdaloid nucleus (Me) integrates pheromonal and olfactory information with gonadal hormone cues, being implicated in social behaviors. It is divided cytoarchitectonically in an anterodorsal, anteroventral (MeAV), posterodorsal and posteroventral part, whose projections are well characterized, except for those of the tiny MeAV. Here, MeAV efferents were examined in the rat with the ...
متن کاملThe medial amygdaloid nucleus modulates the baroreflex activity in conscious rats
The medial amygdaloid nucleus (MeA) is involved in cardiovascular control. In the present study we report the effect of MeA pharmacological ablations caused by bilateral microinjections of the nonselective synaptic blocker CoCl2 on cardiac baroreflex responses in rats. MeA synaptic inhibition evoked by local bilateral microinjection of 100 nL of CoCl2 (1 mM) did not affect blood pressure or hea...
متن کاملSexual differentiation of vasopressin projections of the bed nucleus of the stria terminals and medial amygdaloid nucleus in rats.
The vasopressin-immunoreactive (AVP-ir) projections of the bed nucleus of the stria terminalis (BST) and medial amygdaloid nucleus (MA) are much denser in males than in females even if males and females are treated with similar amounts of testosterone. Previous studies have established that testosterone influences AVP-ir projections during development, but not whether these effects of testoster...
متن کاملA species-specific population of tyrosine hydroxylase-immunoreactive neurons in the medial amygdaloid nucleus of the Syrian hamster.
The medial amygdaloid nucleus (Me) is part of a neural pathway that regulates sexual behavior in the male Syrian hamster. To characterize the neurochemical content of neurons in this nucleus, brains from colchicine-treated adult male and female hamsters were immunocytochemically labeled using antibodies that recognize the catecholamine-synthesizing enzymes, tyrosine hydroxylase (TH), dopamine-b...
متن کاملTyrosine hydroxylase mRNA-containing neurons in the medial amygdaloid nucleus and the reticular nucleus of the thalamus in the Syrian hamster.
To confirm previous immunocytochemical findings in colchicine-treated Syrian hamsters, in situ hybridization was used to investigate the distribution of TH mRNA-containing cells in the medial amygdaloid nucleus (Me) and the thalamic reticular nucleus (Rt) of untreated hamsters. TH mRNA-producing neurons were observed in anterior and posterior Me and throughout Rt, similar to the distribution of...
