Asymmetry
in Function
Cerebral hemispheres appear
symmetric for basic sensory and motor function, sort of
But other higher-order cognitive
functions are asymmetrical, e.g.,
-
Left hemisphere is specialized
for language
-
Right hemisphere is specialized
for spatial processing
Function
of the Corpus Callosum in Vision
Split-Brain
Syndrome
Left hemisphere verbal but
can attend only to right visual field
Right hemisphere mute and
but attends to the left visual field
Demonstrating
Left Hemisphere Language Specialization in "Normals"
Mishgin and Forgays (1952)
presented words briefly to left or right visual field
Replication
study
Left Hemisphere Language Specialization for Language
Right visual field presentation (left hemisphere)
Left visual field presentation (right hemisphere)
