Left Brain, Right Brain: Facts and Fantasies
Michael C. Corballis
Published: January 21, 2014

Summary

Handedness and brain asymmetry are widely regarded as unique to humans, and associated with complementary functions such as a left-brain specialization for language and logic and a right-brain specialization for creativity and intuition. In fact, asymmetries are widespread among animals, and support the gradual evolution of asymmetrical functions such as language and tool use. Handedness and brain asymmetry are inborn and under partial genetic control, although the gene or genes responsible are not well established. Cognitive and emotional difficulties are sometimes associated with departures from the “norm” of right-handedness and left-brain language dominance, more often with the absence of these asymmetries than their reversal.

Handedness, at least, is partly influenced by parental handedness, suggesting a genetic component [50], but genes can't tell the whole story. For instance some 23 percent of monozygotic twins, who share the same genes, are of opposite handedness [51]. These so-called “mirror twins” have themselves fallen prey to a Through the Looking Glass myth; according to Martin Gardner [52], Lewis Carroll intended the twins Tweedledum and Tweedledee in that book to be enantiomers, or perfect three-dimensional mirror images in bodily form as well as in hand and brain function. Although some have argued that mirroring arises in the process of twinning itself [53],[54], large-scale studies suggest that handedness [55],[56] and cerebral asymmetry [57] in mirror twins are not subject to special mirroring effects. In the majority of twins of opposite handedness the left hemisphere is dominant for language in both twins, consistent with the finding that the majority of single-born left-handed individuals are also left-hemisphere dominant for language. In twins, as in the singly born, it is estimated that only about a quarter of the variation in handedness is due to genetic influences [56].

Eu já espalhei o mito do Phineas Gage pela internet afora.

Eu também. Há pouco tempo atrás tinha ouvido uma versão "intermediária" que até já comentei. Essa versão que perde todo o phineas-gageísmo clássico é nova para mim.

Agora os espíritas podem dizer, triunfantemente, "hahaha! E agora, céticos? Cai por terra o principal argumento que tinham para a funcionalidade do cérebro como gerador da personalidade".

Não conhecia esse canal, "serious science", que é realmente sério, esperava algo meio cômico, ironizando.
É algo meio como TED talks de temas científicos, exposições de algum tema em menos de 20m, mas sem todo aquelas firulas de tentar criar "suspense" em comunicação com a platéia. Parece meio que uma entrevista com perguntas cortadas fora.
