Document Summary
Step 3: transduction (physical energy of stimulus convert to energy sent to the brain) Step 4: thalamus (sends info to sensory processing areas; smell) Step 5: psc primary sensory cortex (initial processing of information occurs) Processing of visual information occurs in a series of steps. Hubel and wiesel (1963) examined firing rate of single cells in primary visual cortex: some of the cells called primitives seemed to respond to really specific information (e. g. firing to only seeing a vertical line) Step 6: further processing (higher level cognitive and perceptual tasks; what and where pathways) Many other brain areas (memory, planning, motivation, self-motivation, etc) decide what to do, telling the motor cortex to communicate actions to the muscles. Hubel and wiesel: raised one eyed kittens and measured firing of cells. Cells in visual cortex respond entirely to functioning eye, while blocked eye is disconnected from brain: raised two eyed kittens and measured firing of cells using microelectrodes.
