Document Summary
Sensation: refers to how sense organs respond to and detect external stimulus. Step three: transduction physical energy of the stimulus is converted to electrical energy, which is sent in pulses to the brain. Step four: thalamus the sensory-message switchboard operator, which figures out where to sent it next. Step five: primary sensory cortex initial processing of information occurs. Processing of visual information occurs in a series of steps, from initial coarse processing of relatively basic features (ex. line orientation, colour, movement), to more complex processing (ex. face and object recognition, 3d space) Hubel and wiesel (1963) examined the firing rate of single cells in the primary visual cortex, many were specialized to respond to particular features: primitives . Step six: further processing in many other brain areas, linked to higher level cognitive and perceptual tasks: ex. the what and where pathways. Where: dorsal pathway superior ventral lobes parietal lobes; processes spatial location.
