Document Summary

1: brain receives input from the sensory organs, brain makes sense out of the input from our sensory input. Propagnasia (aka face blindness) can"t recognise people by their face. Sensation sensory receptors and nervous system receive and represent stimulus energies from our environment. Perception organising and interpreting sensory information; enables us to recognise meaningful objects and events the meaning we give to our sensations. Sensation vs perception sensation detection of environmental stimuli. Sense receptors transform physical energy in the environment/body to electrical energy which is then transmitted to the brain as nerve impulses. Doctrine of specific nerve energies signals received by sense organs stimulate different nerve pathways going to different parts of the brain: dendrites are responsible for smell, pressure, pain, temperature. Bottom-up processing taking sensory information and then assembling and integrating it. Top-down processing using models, ideas, and expectations to interpret sensory information.
