Functional laterality appears to be present in many brain functions in man and animals. The existence of paired neural circuits which act differentially to modulate a specific behavioural function seems to be an evolutionary ...

Despite the increasing interest in the use of intro-mittent male genitalia and coercive mating behaviour in poeciliids, detailed studies of the mating behaviour of most species in this family are lacking. We describe here ...

In the present paper we focus on the study of complex behavioural systems, within an explicit phylogenetic framework. We reconstruct the phylogeny of rodents using grooming sequences from 12 terminals. Using a method derived ...

Trace elements are an omnipresent group of chemical elements that are found practically in all types of environments sustaining life. Since its principal characteristic is the very low concentration in ground and water, ...

A previous study of our laboratory have shown that Tellurium (Te), a metalloid with low concentrations in soil and water in the earth, is able to modify important behavioural parameters related to cognitive functions when ...

Background and purpose: Control of food intake is a complex behaviour which involves many interconnected brain structures. The present work assessed if the noradrenergic system in the lateral septum (LS) was involved in ...

Trace elements are an omnipresent group of chemical elements that are present practically in all types of environments sustaining life. Previous evidence from our laboratory has shown that chronic administration of ZnTe ...
