Somatosensation01:33

Somatosensation

43.8K
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 Perception: Organization of the Somatosensory System

11.5K
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...

Overview of Somatic Sensory Pathways

8.9K
Somatic sensory or somatosensory pathways refer to the neural pathways that carry information related to touch, pressure, pain, temperature, and proprioception from the skin, muscles, tendons, and joints to the brain. These pathways involve several stages of processing and integration of sensory information.
The somatosensory system is divided into three main pathways: the dorsal (or posterior) column-medial lemniscus, spinothalamic (or anterolateral), and spinocerebellar pathways.
The dorsal...

Introduction to Special Senses

7.8K
Sensory receptors play an integral part in comprehending our external and internal environments. They receive diverse stimuli, converting them into the nervous system's electrochemical signals. This conversion occurs as the stimulus alters the sensory neuron's cell membrane potential, instigating the generation of an action potential. This action potential is subsequently transmitted to the central nervous system (CNS), which integrates with other sensory data or higher cognitive...

Major Somatic Sensory Pathways

3.1K
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...

Sensory Modalities01:15

Sensory Modalities

4.0K
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...

Summary

Somatosensory amplification, linked to symptom reports, may involve more than body sensations. It appears to amplify perceptions of both internal and external bodily threats, expanding its conceptual scope.

Area of Science:

  • Psychology
  • Psychosomatic Medicine
  • Clinical Psychology

Background:

  • Somatosensory amplification significantly influences symptom reporting.
  • Its association with negative affect is empirically supported.
  • Key original components like body hypervigilance and focusing on mild sensations remain under-addressed.

Purpose of the Study:

  • To review and summarize the history and development of somatosensory amplification.
  • To explore recent findings connecting somatosensory amplification to broader phenomena.
  • To propose a revised conceptualization of somatosensory amplification.

Main Methods:

  • Literature review and synthesis of historical and recent empirical findings.
  • Analysis of the construct's evolution and its relationship with various psychological phenomena.
  • Conceptual re-evaluation based on current evidence.

Main Results:

  • The original concept's focus on bodily events alone is insufficient.
  • Somatosensory amplification is linked to modern health worries and medication side effect expectations.
  • Connections to the perception of external threats have been identified.

Conclusions:

  • Somatosensory amplification should be reconceptualized as "somatic threat amplification".
  • This broader concept encompasses the intensification of perceived external and internal threats to bodily integrity.
  • The revised understanding has significant practical implications for clinical practice and research.
