The evolution of contralateral control of the body by the brain: Is it a protective mechanism?

Abstract: Contralateral control, the arrangement whereby most of the human motor and sensory fibres cross the midline in order to provide control for contralateral portions of the body, presents a puzzle from an evolutionary perspective. What caused such a counterintuitive and complex arrangement to become dominant? In this paper we offer a new perspective on this question by showing that in a complex interactive control system there could be a significant net survival advantage with contralateral control, associated wi… Show more

“…Simultaneously, this phenomenon occurred in the frequency interval V, and the coupling direction was from RPFC, RMC, ROC, and LOC to LMC. This phenomenon might be correlated with the habit of the right–handedness of the subjects, as a mechanism derived from the contralateral control of the brain 80 . However, the coupling direction in the TCC group during the resting state was from PFC, LMC, and OC to RMC, which was different from that of the left brain drive pattern in the control group.…”

“…6 Međutim, iako su polutke mozga u jednoj mjeri specijalizirane za određene funkcije koje obnašaju (primjerice procesiranje govora i jezika smješteno je u lijevoj polutci, Brockinu i Wernickeovu području), one su u stalnom kontaktu zbog principa kontralateralnosti (organizacije mozgovnih polutki koje u najvećoj mjeri motorički i senzorički inerviraju suprotnu stranu tijela). 7 Najnovija metaanaliza, koja je uključila više od dva milijuna sudionika iz cijelog svijeta, ukazuje na dominantnost desnorukosti te procjenjuje svjetsku prevalenciju ljevorukosti od 10,6 %. 8 Lateralnost ili dominantnost u upotrebi jedne strane tijela razvija se tijekom djetinjstva, počinje se stabilizirati s polaskom u osnovnu školu, a potpuna stabilnost koja se može usporediti s onom odrasle osobe može se uspostaviti tek između 10 i 12 godina.…”

“…The emergence and evolution of noninvasive functional techniques, such as magnetic resonance imaging (fMRI) (Seghier 2008) and functional near-infrared spectroscopy (fNIRS) (Khaksari, Smith et al 2021, Zuniga, Pierce et al 2021, are now providing an additional characterization of cortical lateralization. This lateral dominance has been observed in a variety of species and is very likely tied to increased survival (Whitehead and Banihani 2014). The more prevalent contralateral dominance of motor control has, however, been found to adapt to various factors within the body.…”
