What are the three levels of sensory integration?

Summary Introduction

To review:

The three levels of sensory integration.

Introduction:

The PNS (peripheral nervous system) is a segment of the nervous system that have all the neural structures found outside the brain as well as the spinal cord. These structures include sensory receptors, different motor endings, and peripheral nerves and their linked ganglia.

Explanation of Solution

The survival of the human beings does not purely depend on the sensation, which is basically the awareness of the alterations in the external as well as internal surroundings, however also on the perception, which is the conscious interpretation of stimuli. When someone steps on the pebble, it causes the sensation of the localized intense pressure, however, the perception is the awareness of the discomfort.

The somatosensory system is basically the segment of the sensory system, which serves the limbs as well as body wall and it gets inputs coming from the interoceptors, exteroceptors, and proprioceptors. Subsequently, it also sends the information to different sensory modalities or kinds of sensations. There are three basic levels of the neural integration, which work in the somatosensory system and these are:

1. Receptor level, which is sensory receptors.

2. Perceptual level is processing in the cortical sensory regions.

3. Circuit level is regulating the ascending pathways.

Conclusion

Therefore, it can be concluded that the three main levels are a receptor, circuit, and perceptual level.
