ABSTRACT

Aim: Many particularities concerning interhemispheric differences still need to be explored and unveiled. Functional and anatomical differential features found between left and right brain sides are best known as asymmetries and are consequence of the unilateral neuronal recruitment or predominance that is set to organize some function. The outflow from different neural pathways involved in the autonomic control of the cardiovascular system may route through asymmetrically relayed efferences (ipsilateral/lateralized and/or contralateral). In spite of this, the literature reporting on the role of central nuclei involved in the autonomic control is not always dedicated on these interhemispheric comparisons. Considering the recent reports demonstrating that asymmetries may set differential functional responses, it is worth checking differences between right and left sides of central regions. This review aims to inspire neuroscientists with the idea that studying the interhemispheric differences may deepen the understanding on several centrally controlled responses, with special regard to the autonomic functions underlying the cardiovascular regulation.

Conclusions: Thus, an avenue of knowledge may unfold from a field of research that requires further exploration.
