Document Summary

Information goes from the retina to the primary visual cortex. Information from the visual cortex takes 2 routes: dorsal: to the posterior parietal lobe. Locating objects in space: ventral: to the temporal lobe. Work with brain damaged patients suggested functionalities realized by the two lobes: ex. Patients with parietal cortex damage had a hard time locating objects: don"t know if these parts of the brain originate the function or if it provides input to another part of the brain. Cross-lesion disconnection experiments: trace connections between cortical areas to uncover pathways along which information flows. Method: surgically remove specific brain regions in order to discover connection between them. Landmark task: choose one of two food wells depending on proximity to landmark (closer to cylinder) No single pathway specialized for processing visual information. Information takes different routes depending on the type of information. Marr = top-down (start with computational and work towards implementation)
