Document Summary
Sensation refers to how sense organs respond to and detect external stimulus energy, and how those responses are transmitted to the brain. Perception refers to the brain"s further processing of detected signals and results in an internal representation. Step 3: transduction: physical energy of stimulus is converted to electrical energy, which is sent in pulses to the brain. Step 4: thalamus: the sensory-message switchboard operator, which figures out where to send it next. Step 5: primary sensory cortex: initial processing of information occurs. Step 6: further processing in many other brain areas, linked to higher level cognitive & perceptual tasks: e. g. , the what & where pathways. Step 7: deciding & acting: many other brain areas (involving memory, planning, motivation, self-control, etc. ) then decide what do, and tell our motor cortex to communicate the appropriate actions to muscles in the body
