As demonstrated recently at SFN by Wilson et al., there is a clear left-hemisphere bias of brain depictions.
[…] An argument based on the prevalence of right-handed illustrators cannot explain the bias seen in photographs of the brain. Some colleagues have suggested that the bias reflects the left-to-right nature of English writing, but we find this argument less than compelling, especially given the lack of a bias in how the head is represented. We remain hopeful that our colleagues who study laterality might be able to offer an explanation.
Thus, I found this chocolate right hemisphere all the more remarkable.
