Although the two halves are so physically similar that if you were asked to match brain halves of different people you could do so easily, the two halves are functionally different the left hemisphere is in charge of language functions and logical thought speech, song, and writing are all examples of left.

Language lateralization • split-brain patients: evidence for lateralization ▫ in the past, some cases of severe epilepsy were treated by cutting the corpus callosum, severing the connection between the two hemispheres • messages sent to the hemispheres cause different responses in split-brain patients ▫ object placed in. The lateralization of brain function is the tendency for some neural functions or cognitive processes to be more dominant in one hemisphere than the other the medial longitudinal fissure separates the human brain into two distinct cerebral hemispheres, connected by the corpus callosum although the macrostructure of the.

Studies of patients who have had commissurotomies (split-brain patients) have provided significant information about language lateralization al, 2007) as such, split-brain patients have presented substantial evidence that language function is generally lateralized in the left hemisphere.

  • Moreover, supporting evidence substitutes the fact that linguistic function can completely switch itself to the right hemisphere of the brain, when the left one is damaged this is the interesting part in lateralization, is attempting to track in what way the two sides of the brain contribute to language indeed.
  • Essay review limits on plasticity nelson & luciana (eds) handbook of developmental cognitive neuroscience (2001) anderson, northam, hendy & wrennall the more scientists learn about the brain, the more we learn about its infinite plastic- the left lateralization of some aspects of language is but one example.
