Sensory Processes

This chapter provides an overview of sensory processes. It starts with the organisation of sensory systems in line with the classification of sensory receptor cells. Sensory systems provide animals with essentially all of the information they have about their external environment and their internal environment. Moreover, sensory systems of all kinds depend on specialised sensory receptor cells that respond to stimuli, either from the environment or arising inside the body. Sensory cells respond to different stimuli that vary greatly in sensitivity and specificity. The chapter then looks into the features and functions of vestibular organs, chemoreception, olfaction, photoreception, and visual sensory processing.
