Sensory System

Fig.1 Sensory System

The sensory nervous system is a part of the nervous system and is responsible for processing sensory information. The sensory system consists of sensory neurons (including sensory receptor cells), neural pathways and parts of the brain involved in sensory perception. The recognized sensory system is the system for sight, hearing, touch, taste, smell and balance.

Organisms need information to solve at least three problems: (a) maintain an appropriate environment, that is, homeostasis; (b) schedule activities (for example, seasonal changes in behavior) or synchronize activities with specific activities; (c) find and respond to resources or threats (for example, by turning to resources or evading or attacking threats). The receptive field is the area of the body or environment where the recipient organ and the recipient cell react with. For example, the part of the world that the eye can see is its receiving area. The light that each rod or cone can see is its receiving field.

Sensory Cortex

The five traditional human senses include the primary and secondary cortex of different senses: somatosensory cortex, visual cortex, auditory cortex, main olfactory cortex and taste cortex.

Somatosensory cortex—The main somatosensory cortex is located in the parietal lobe and is the main receiving area of touch and proprioception in the somatosensory system. The cortex is further divided into Brodmann zones 1, 2 and 3. Brodmann area 3 is considered to be the main processing center of the somatosensory cortex because it receives a large amount of input from the thalamus, has neurons that are highly sensitive to somatosensory stimulation, and can induce the sensation of somatic cells through electrical stimulation.

Visual cortex—The visual cortex refers to the main visual cortex labeled V1 or Brodmann area 17, and the supra-optical cortex area V2-V5.

Auditory cortex—The auditory cortex is located in the temporal lobe and is the main receiving area for sound information.

Olfactory cortex—The primary olfactory cortex is located in the temporal lobe and is the main receiving area for smell or olfaction. At least in mammals, what is unique to the olfactory and taste systems is the realization of peripheral and central mechanisms of action.
