There is evidence to suggest that the antidepressant activity of sleep deprivation may be due to an enhancement of serotonergic and/or noradrenergic neurotransmission in brain. in the present study we examined the possibility ...

The amygdala complex is a heterogeneous group of temporal lobe brain structures involved in the processing of biologically significant sensory stimuli and in the generation of appropriate responses to them. The amygdala ...

The dorsal premammillary nucleus (PMd) has a critical role on the expression of defensive responses to predator odor. Anatomical evidence suggests that the PMd should also modulate memory processing through a projecting ...

The cortical amygdala receives direct olfactory inputs and is thought to participate in processing and learning of biologically relevant olfactory cues. As for other brain structures implicated in learning, the principal ...

We have made quantitative volumetric analyses of cerebral cortical (pallial) structures in the brains of three species of monotreme (Ornithorhynchus anatinus, Tachyglossus aculeatus, Zaglossus bruijni) and compared the ...

Social behavior is essential for hierarchy, mating, territorial aggression, affiliation and parental care. Thus, the species survival depends of this behavior. However,so far, the molecular basis of social behavior has not ...
