The infralimbic area (IL) and prelimbic area (PL) have been postulated as an autonomic motor region in the medial prefrontal cortex. The present study was conducted to reveal the projection sites of IL and PL of the monkey, Macaca fuscata, using biotinylated dextran amine as an anterograde tracer. IL and PL projected densely to the ventromedial caudate nucleus, the core and shell of the nucleus...

Lesions in the medial forebrain bundle rostral to a stimulating electrode have variable effects on the rewarding efficacy of self-stimulation. We attempted to account for this variability by measuring the anatomical and functional effects of electrolytic lesions at the level of the lateral hypothalamus (LH) and by correlating these effects to postlesion changes in threshold pulse frequency (pps...

Arginine vasopressin plays an important role in the regulation of social behaviours in rodents. In the Syrian hamster, vasopressin injected directly into the brain stimulates scent marking and aggressive behaviour in a steroid dependent manner and is therefore a useful model for investigating steroid-peptide-behaviour interactions. In this study, we used in situ hybridization and radioligand bi...

Reproduction induces changes within the brain to prepare for gestation and motherhood. However, dynamic of these central their relationships with development maternal behavior remain poorly understood. Here, we describe a longitudinal morphometric neuroimaging study in female mice between pre-gestation weaning, using new magnetic resonance imaging (MRI) resources comprising high-resolution temp...

The influence of 48 h food deprivation on the levels of catecholamines was investigated in different hypothalamic and telencephalic nuclei of the rat brain. There were on changes in the levels of noradrenaline (NA) and dopamine (DA) in the lateral hypothalamic area, dorsomedial nucleus, medial preoptic area and in nucleus of diagonal band (septum). On the other hand we observed a statistically ...
