Tactile and Chemical Senses

Tactile and Chemical Senses

Tactile senses encompass touch, temperature, and pain, each mediated by specific receptors. Touch receptors detect mechanical energy or pressure against the skin. Sensory fibers from these receptors enter the spinal cord and relay information to the brain stem. Here, most fibers cross over to the opposite side of the brain. The touch information then moves to the thalamus, which projects a map of the body's surface onto the somatosensory areas of the parietal lobes in the cerebral cortex. This...

Somatosensation

Somatosensation

The somatosensory system relays sensory information from the skin, mucous membranes, limbs, and joints. Somatosensation is more familiarly known as the sense of touch. A typical somatosensory pathway includes three types of long neurons: primary, secondary, and tertiary. Primary neurons have cell bodies located near the spinal cord in groups of neurons called dorsal root ganglia. The sensory neurons of ganglia innervate designated areas of skin called dermatomes.

Sensory Modalities

Sensory Modalities

Sensation typically is the process by which the sensory receptors and sense organs detect stimuli from the internal and external environment and transmit this information to the central nervous system for processing.
General senses refer to the broad category of sensory information detected by receptors in the body and can be further grouped into somatic and visceral senses. Somatic sensations include touch, pressure, temperature, and pain and are essential for navigating our environment and...

Major Somatic Sensory Pathways

Major Somatic Sensory Pathways

Sensory impulses related to touch, pressure, vibration, and proprioception from various body parts, such as the limbs, trunk, neck, and posterior head, travel to the cerebral cortex through the posterior column-medial lemniscus pathway. The pathway’s name derives from the two white-matter tracts that convey the impulses: the spinal cord's posterior column and the brainstem's medial lemniscus. First-order sensory neurons extend their axons into the spinal cord, forming the posterior columns...

Sensory Perception: Organization of the Somatosensory System

Sensory Perception: Organization of the Somatosensory System

The somatosensory system is the central and peripheral nervous system component that senses and processes touch, pressure, pain, temperature, and body position or proprioception. The process of sensation takes place at three levels:
The receptor level:
The receptor level is the first stage of sensation. It involves the detection of a stimulus by specialized sensory receptors. The stimulus must arrive within the receptor's receptive field. Next, the receptor converts the energy of the stimulus...

Summary

This summary is machine-generated.

This study proposes a new movement classification based on somatosensory roles. Exploratory movements, crucial for object feature extraction, involve parallel sensorimotor predictions for hypothesis testing.

Area of Science:

Neuroscience
Sensory-motor control
Animal behavior

Background:

Somatosensory input is linked to motor output, but not vice-versa.
A continuum for movement classification based on somatosensory roles is proposed.

Purpose of the Study:

To classify movements based on the role of somatosensory information.
To distinguish exploratory movements and their unique characteristics.

Main Methods:

Proposed a movement classification scheme.
Analyzed the role of somatosensory information in different movements.
Utilized the rat vibrissal system as a model.

Main Results:

Fine sensorimotor control, including manipulation and exploration, represents one extreme of the movement spectrum.
Exploratory movements allow feature extraction independent of movement sequence.
Object exploration involves parallel cognitive and control-level sensorimotor predictions.

Conclusions:

Exploration may involve cognitive hypothesis testing and control-level predictions.
Sensorimotor predictions at cognitive and brainstem/cerebellar levels are key to exploration.
