Document Summary

A lot of fibres actually cross the midline when going into the cerebellum: such as fibres from the pontine nuclei, crosses at the spinal cord, ascends, through peduncle and crosses within, even output pathways are contralateral. What they meant to say is that the function of the cerebellum is ipsilateral. Recall: how does mental stress result in cardiovascular output: changes in autonomic nervous system. Insular cortex: visceral cortex, dorsal prefrontal cortex: planning to be perfect. Both on the left side of the cerebral cortex. Inability to understand sensory stimuli: tactile (near somatosensory region): do not understand touch, visual (in the occipital lobe): do not understand what seeing, auditory (superior temporal lobe): do not understand what hearing, primary cortex areas intact. Summary: agnosia: a defect in understanding sensory information, apraxia: impairment in the performance of learned movements, aphasia: damage to language areas or their connections (left hemisphere), aphonia: inability to produce sounds or speech.
