Ch 4 02/16/2016 ▯ An Exploration of Spatial Organization  Magnification factor o When you look at a scene the area you are looking at takes up more space in your cortex than something of the same size of to the side, things in our direct vision take up more space in our visual cortex  More space on the cortex translated into better detail vision rather than larger size  Huble and Wiesel discovered that the striate cortex is organized in columns that are perpendicular to the surface of the cortex, so that all of the neurons within a location column have their receptive fields at the same location on the retina  A location column which contains the full range of orientation columns (hyper column) ▯ Streams: Pathways for What, where and how  Streams transmit information from the striate cortex to other areas in the brain  Object discrimination- ex picking the correct shape when presented with an object, lesioning (ablation) in the temporal lobe makes this task difficult  Landmark discrimination- pick the object that is closest to a diferent object, lesioning (ablation) of the parietal lobe makes choosing difficult  Pathway that leads to Temporal lobe is where object’s identifies are
