Document Summary

Sense: system that translates outside information into activity in the nervous system (smell, hearing, sight). Sensation: raw information from the senses (involves accessory structures and transduction). Perception: the process of making sensations into meaningful experiences.

Sensory receptors respond best to changes in energy. Adaptation is a decreasing responsive to constant stimulation over time. Coding translates the physical properties of stimulus into patters of neural activity. Coding conveys intensity and location and interprets what just happened. Accessory structures: structures in sensory systems that modify an incoming stimulus. Transduction: the process by which an incoming stimulus is converted to neural signals. Accessory structures and transduction transduction occurs at specialized cells called receptors.

Sensitivity: ability to discriminate a stimulus from its background.
