  • Abstract
  • Look Inside

Modern study of the function of the corpus callosum has been started in 1950s with an ingenious split-chiasma and split-brain technique developed by Myers, Sperry and their colleagues. These experiments have clearly shown that, in experimental animals such as cats or monkeys, the corpus callosum and/or the anterior commis-sure play essential roles in the transfer of learn-ing including visual discrimination, tactile dis-crimination, and others. Many exceptions, however, were also reported regarding the transfer of learning. For example, visual discrimination learn-ing of simpler figures, brightness and color is more likely to be transfered to the untrained hemisphere in split-brain animals. Motivation of learning task also modifies the result of learning transfer. In these conditions, subcortical pathways are supposed to be working for the transfer of learning.
