	Sensory system - Wikipedia, the free encyclopedia
		A sensory system consists of sensory receptors, neural pathways, and parts of the brain involved in sensory perception.
		In the memory-prediction framework, Jeff Hawkins mentions a correspondence between the six layers of the cerebral cortex and the six layers of the optic tract of the visual system.
		The somatosensory system feeds the Brodmann Areas 3, 1 and 2 of the primary somatosensory cortex.

	The Somatic Sensory System
		All sensory systems are organized in more or less the same way, so I'll first introduce some general principles of how the sensory nervous system works and then focus on the kinds of sensation that are detected by the somatic sensory (or somatosensory) system.
		In somatic sensory neurons, the trigger zone is usually adjacent to the receptive region of the neuron, so activation of the receptive region may cause an action potential that is then propagated all the way to the synapses that the sensory neurons make onto other neurons in the spinal cord.
		The sensory endings of the axons that enter a given dorsal root are normally clustered together on the surface of the body.

		Sensory integration is a term used to describe the way in which the brain sorts out and organizes for our use the many sensations which we receive.
		Sensory Integrative Treatment was developed out of the extensive research of A. Jean Ayres, an occupational therapist with a strong interest in the sensory systems and sensory integrative dysfunction (Ayres 1964; Ayres 1965; Ayres 1966; Ayres 1972).
		For example, although two children with sensory organizing difficulties responded poorly to the tapes, a third child whose clinical behaviors were similar, responded positively and made major gains in reducing seizures, improving her focus of attention, and developing some basic communication skills when Hemi-Sync tapes were included in her program (Morris 1983).

	[P&S Medical Review:December:95] Review: Molecular Analysis of Sensory Processing in the Olfactory System
		A fuller understanding of molecular recognition and higher sensory processing in the olfactory system was made possible by the cloning of the odorant receptor genes in 1991 by Linda Buck and Richard Axel at the College of Physicians and Surgeons (Figure 1).
		In other sensory systems, the spatial segregation of neurons or their projections is used to indicate the quality of the stimulus.
		The discovery of the convergence of sensory axons in the olfactory bulb suggests that a given odor may be represented in the cerebral cortex as the combinatorial activation of different glomeruli.

	Sensory Integration - Habilitation Services. (Site not responding. Last check: 2007-11-07)
		Sensory integration is the ability of the central nervous system to organize and process input from various sensory channels in order to make an appropriate response.
		In sensory integration therapy, the child is guided through activities that challenge his or her ability to respond appropriately to the sensory input.
		Although sensory integration is a standard treatment for an individual with autism, very few efficacy studies of the approach with children with autism have been published.

	Sensory System (Site not responding. Last check: 2007-11-07)
		We have considered the nervous system and are aware that it receives information about the environment from a sensory system consisting of a wide variety of receptors specialized to detect some specific environmental event.
		Sensory, or receptor, cells may operate singly, as in the case of simple photoreceptors in the skin of earthworms, more often in association with other receptors and supporting, non-sensory cells to form a sense organ.
		An action potential is generated in a sensory neuron known as the bipolar cell and then passed to sensory neurons known as ganglion cells whose axons make up the optic nerve and transmit the action potential to the brain.

	Enzymes & Sensory Integration
		Sensory integration is the process of the body compiling all of the external stimuli and signals from the environment, analyzing it, organizing it, and integrating it.
		With sensory integration dysfunction, one’s nervous system is not able to properly sort out and make sense of all the sensory input that the senses are taking in.
		Using Epsom salts can greatly relieve the stress on the body and sensory system for several reasons - both for the magnesium that helps with calming and is often deficient; and for the sulfate that helps with detoxification.

	Sensory Integration Dysfunction
		When an individual has sensory integration dysfunction, he or she may be unable to respond to certain sensory information to plan and organize what he or she needs to do in an appropriate and automatic manner.
		Using the example of crossing the street, an individual with sensory integration dysfunction may be unable to process the sound of the blowing horn, causing him or her to freeze (a fright response--as a deer caught in a spotlight).
		The fact that sensory integration dysfunction is generally not a visible disability, the child may be treated unfairly or the disability not be given consideration.

	Reference.com/Encyclopedia/Nervous system
		The peripheral nervous system can also be roughly seen as consisting of sensory pathways and motor pathways, the latter being divided into the somatic (voluntary) nervous system and the autonomic nervous system.
		The sympathetic nervous system responds to impending danger or stress, and is responsible for the increase of one's heartbeat and blood pressure, among other physiological changes, along with the sense of excitement he feels.
		The parasympathetic nervous system, on the other hand, is evident when a person is resting and feels relaxed, and is responsible for such things as the constriction of the pupil, the slowing of the heart, the dilation of the blood vessels, and the stimulation of the digestive and geniturinary systems.

	Center for the Study of Autism
		Sensory integration is an innate neurobiological process and refers to the integration and interpretation of sensory stimulation from the environment by the brain.
		In contrast, sensory integrative dysfunction is a disorder in which sensory input is not integrated or organized appropriately in the brain and may produce varying degrees of problems in development, information processing, and behavior.
		The therapist's general goals are: (1) to provide the child with sensory information which helps organize the central nervous system, (2) to assist the child in inhibiting and/or modulating sensory information, and (3) to assist the child in processing a more organized response to sensory stimuli.

	OT Outcomes - Neurological Systems That Support Sensory Processing
		Sensory information is constantly coming into our bodies through our five senses, as well as internally, through our muscles, joints and movement receptors (in the inner ear).
		The sensory systems serve as the foundation for all self-awareness, motor skill, relational abilities, communication and learning - one's human occupation throughout the lifespan.
		The Proprioceptive System is part of the vestibular system, where special receptors in muscles and joints travel quickly from the cerebellum to enhance tone and joint stability.

		The design of the system and the flow of data through it are derived from its definition as an information gathering system that is customizable and tunable, but stable and intelligible in its output.
		In this system, AI senses are framed in terms of "awareness." Awareness is expressed as a range of discrete states that represent an AI's certainty about the presence, location, and identity of an object of interest.
		The alertness state of the AI is fed back into the sensory system in various ways to alter the behavior of the system.

	PsychNotes
		As a general concept, the basic functions of all of the sensory modalities are the same, to respond to a specific peripheral stimulus (smell, taste, sound, light or touch) and translate that stimulus into neuronal signals that can be processed to create an internal representation of the external world.
		A review by DeWeese and colleagues, explores the possibility that these 'extra' neurons are used to counteract the effects of noise that results from moving the sensory signal along the processing stream and to thereby assure a reliable representation of the peripheral signal.

		The sense management system is designed as a series of components each taking a limited and well-defined set of data and outputting an even more limited value.
		The core sensory system implements heuristics for accepting visibility, sound events, current awareness links, designer and programmer configuration data, and current AI state, and outputting a single awareness value for each object of interest.
		Thus incorporating such a system as described here is something to do deliberately and with care, as it will place information demands on other systems.

	Basic Somatosensory Pathway
		Any sensory system going to the cerebral cortex will have to cross over at some point, because the cerebral cortex operates on a contralateral (opposite side) basis.
		The system that is carried in the spinal cord includes the entire body from the neck down; face information is carried by cranial nerves, and we will come back to it later.
		The sensory neurons are unique because unlike most neurons, the signal does not pass through the cell body.
