Document Summary
L + r cerebral hemispheres are separated by the great longitudinal fissure (containing the falx cerebri) Corpus callosum (white matter) commissural fibres joins the 2 hemispheres together. Cerebrum linked to brain stem + spinal cord. Largest commissure/neocortical commissural tract between the two cerebral hemispheres. Connection between cortical areas of similar function in both hemispheres. Incortical hemispherectomy remove the hemisphere + part of the corpus callosum for that hemisphere, meaning that the 2 hemispheres can no longer communicate, but neuroplasticity (in. Infants) means that the other hemisphere with the same function will start to take over the job of the same area that was cut out in the other hemisphere. Some fibres from the cortex are funneled down like a radiating crown of white matter = corona. These projection fibre axons are then funnelled down even further into an internal capsule. From internal capsule the projection fibres go down to places like, thalamus, brain stem,
