General principles of neurologic localization -- Peripheral nerves -- Cervical, brachial, and lumbosacral plexuses -- Spinal nerve and root -- Spinal cord -- Cranial nerve I (the olfactory nerve) -- Visual pathways -- The localization of lesions affecting the ocular motor system -- Cranial nerve V (the trigeminal nerve) -- Cranial nerve VII (the facial nerve) -- Cranial nerve VIII (the vestibulocochlear nerve) -- Cranial nerves IX and X (the glossopharyngeal and vagus nerves) -- Cranial nerve XI (the spinal accessory nerve) -- Cranial nerve XII (the hypoglossal nerve) -- Brainstem -- The cerebellum -- The localization of lesions affecting the hypothalamus and pituitary gland -- The anatomic localization of lesions in the thalamus -- Basal ganglia -- The localization of lesions affecting the cerebral hemispheres -- Vascular syndromes of the forebrain, brainstem, and cerebellum -- The localization of lesions causing coma.
