LAB 7: CEREBRAL CORTEX - FUNCTIONAL AREAS AND BLOOD SUPPLY

Student Preparation Guide

Objectives

  • Describe and localize the lobes of the cerebral cortex and their major components.
  • Compare and contrast the functional components of the right and left hemispheres. Localize the functional areas.
  • Analyze the deficit that would result from cortical lesions to the different functional areas. Differentiate between right and left hemisphere lesions.
  • Explain the classical cortical representation of language and its clinical significance.
  • Describe the location of the major subcortical fiber bundles.
  • Describe the tracts running through the internal capsule, their location within the internal capsule, and the blood supply to the internal capsule.
  • Describe the function of the thalamus as the gatekeeper to the cortex. Describe which systems relay through the thalamus.
  • Review the visual system. Describe and localize the relevant tracts and structures.
  • Describe the blood supply to the forebrain.
