Document Summary
Our sensory systems deliver this envoi to us / enviro is constructed by animal"s sensory systems. Animal lives in this world (they can actually perceive this) They only perceive few things in their world/umwelt. Butyric acid (respond to skin of all animals), mechanical stimulation (motion), warmth of host. Higher sensory systems: the nervous system decomposed environmental stimuli into separate components, then re-assembles the components into a representation of the external world. Binaural fusion: two ears receive separate auditory input but perceive a sound as originating from a single location in space. Difference between two ears in sound reception: Time difference - can tell where the sound comes from. Location of a sound can be determined from differences in sound reception by the two ears: A 1 kiloherz tone oscillates 1,000 times per second. Maximum neural ring rate is several hundred times per second.
