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.

Summary

This summary is machine-generated.

Receptive field (RF) remapping in the parietal cortex allows visual fields to shift before eye movements (saccades). This review clarifies how RF remapping observations depend on sampling methods and discusses its neural basis and computational role.

Background:

Receptive field (RF) remapping in the parietal cortex was discovered 25 years ago.
Visual RFs were previously assumed to have fixed retinotopic organization.
RFs change position before every saccade, a phenomenon known as remapping.

Purpose of the Study:

To review the complexities and varying observations of RF remapping.
To explain how spatial and temporal sampling influence RF remapping measurements.
To summarize theories on the neural mechanisms of remapping and its functional implications.

Main Methods:

Review of existing neurophysiological and psychophysical studies on RF remapping.
Analysis of how different sampling strategies affect remapping observations.
Synthesis of theoretical models explaining remapping circuitry.

Main Results:

RF remapping observations are sensitive to spatial and temporal sampling parameters.
Various theories exist regarding the neural circuitry underlying remapping.
Remapping information is proposed to aid computations in downstream brain areas.

Conclusions:

Understanding RF remapping requires careful consideration of measurement techniques.
Theories on remapping mechanisms are diverse and evolving.
RF remapping plays a crucial role in visual information processing and sensorimotor integration.
