Question

If a picture of an object is projected onto the left visual field of a split-brain individual who is subsequently asked to select the object by touch from an array of objects (without viewing them), would you expect him to be able to identify it? What have experiments (such as this one) on split-brain individuals elucidated? How have research findings from diffusion tensor imaging (DTI) challenged the connectionist model of aphasia?

Answer 1

Ans. The subject would be unable to identify the object as the cerebral hemisphere of the somatosensory cortex represents only the tactile representation thus the subject would be unable to identify the subject.

DTI technique utilises the mapping and characterisation of the white matter in the brain. It has been used for redefining the cortex borders and suggesting the hemispheric assymetry in the connectivity of the structures and provides a detailed view about the map and structure of the connectivity.
