Document Summary
Perception linked but description is a little false. Seeing a red apple the detection of objects, their location, their movements, their background. seeing purple and blue in the picture is sensation, whereas seeing beautiful fireworks is perception. + seeing movement is sensation but seeing a soccer ball coming toward us and realizing that we will have to move the left to block it is perception. How do these messages from the world get transferred into our body? our senses are input from the world through transduction. Transduction is the process by which sense organs convert energy from environmental events into neural activity, eventually ending up in the brain. Sense organs detect stimuli provided by light, sound odor, taste or mechanical contact w/ environment info. about these stimuli transmitted to the brain through neural impulses action potentials carried by axons in sensory nerves.
