Document Summary
The steps to perceptual processing: physical stimulus, sense organs, receptor cells in sensory surface (transduction, neurons/brain (encoding/transmission, perception ooooooo. We have special sensory systems to detect these stimuli. Perception is a product of evolution: different creatures perceive the world differently. Sense organs: funnel the physical stimulus to specialized receptor cells (located in the sense organs) (duh ik okay cool) that can detect that stimulus. The cells in the sense organs: detect the physical stimulus, transduce physical stimuli into neural signals (all the different languages of the world and all translated to the neural signals) Receptive fields-area on a sensory surface that have rcs from which the neuron gets signals. Can have one sensory cell or a shit ton of sensory cells. They can be spread out or like super close together. Any sensory cell can be a part of one or more neuron"s receptive field.
