We report a role for the tectal and posterior commissural system (TC/PC) in functional lateralization of the chicken brain. Unlike the corpus callosum of mammals which is thought to generate lateralization, the TC/PC in the chicken brain is shown to suppress lateralization. The TC/PC was sectioned on day 2 post-hatching. The performance of this TC/PC-sectioned group on a battery of monocular, behavioural tests was compared to a sham-lesioned group and an untreated group. The first of these… CONTINUE READING
