Document Summary

Animals provide insight into human brain function. Studying patients with a single neurological impairment link brain structures to specific cognitive functions. E. g. , post-mortem studies by broca and wernicke linked the left hemisphere with language. Tan could only say tan , although he could understand spoken language. Autopsy found a lesion in the left inferior frontal cortex. Video in class, counts to 20, he understands he sounds like that, stroke in that area of the brain. Linking injury (l frontal lobe) to personality. Dorsal stream where pathway" and ventral stream what pathway" = dual steam hypothesis. Had bilateral lesions in the lateral occipital complex due to hypoxia. Caused an inability to identify objects based on their shape. But can interact with the object (d stream ok) See in epileptics (e. g. , 51 y/o epileptic patient, l side of brain asleep") **put half the brain asleep to determine if damage tissue needs to be removed** Stimulation of the somatosensory cortex area: somatic sensation.
