Document Summary

Provide info to our brain from the outside world; includes other sensory systems as well. Stimuli: physical events that can be detected by our senses. Sensory receptors: special neurons that detect a particular category of physical events. Sensory transduction: process by which info about stimuli are converted. Most of what goes on includes cortical process; the func of the cortex: what the cortex does by closely observing a sensory sys. Strong homology b/w species; many display this trait & can manipulate visual stimuli. Easy to design expt o o: dominant sense in humans; most research is done regarding this sensory sys (best studied sensory process) What is light: generated by photons; particles of e & waves of electromagnetic radiation; move fast. Amplitude height of waves; to crest or trough. Sensitivity the ability to see when light is dim. Acuity the ability to see detail o o o o.
