Document Summary
Generally, the graph known as an audiogram is charted with frequency levels (hz) on the x-axis and the decibel levels (db) on the y-axis: however, normal human hearing can occur with sounds outside of the speech banana. These sounds include ambient natural sounds such as a rustling of leaves in the wind or birds chirping. What they need to be sensitive to (predators; pretyetc) Structure of receptor organ and receptor cells. Species differences also in terms of sensitivitiy and discrimination. Mice discriminate more odors than we do. When light hits an object, some is absorbed some reflected. Each sensory system gets its own thalamic nucleus: cortex, conscious perception & high level evaluation. Tonotopic, somatotopic, retinotopic: somatotopy is the point-for-point correspondence of an area of the body to a specific point on the central nervous system. Know examples from the auditory and visual system, and from aspects of pain perception: amplitude and loudness, frequency and pitch, pain, visual system in general!
