Major Somatic Sensory Pathways01:28

Major Somatic Sensory Pathways

3.2K
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...

Somatosensation01:33

Somatosensation

36.8K
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.

Somatic Spinal Reflexes01:22

Somatic Spinal Reflexes

7.7K
Somatic spinal reflexes are rapid, involuntary muscular responses to external stimuli that involve the somatic musculature and the spinal cord.
One of the most well-known somatic spinal reflexes is the stretch reflex, which is activated by the sudden stretching of a muscle. This reflex involves the activation of specialized sensory receptors called muscle spindles, which are located in the muscle tissue and detect changes in the length and speed of muscle contractions. When a muscle is suddenly...

Overview of Somatic Sensory Pathways

9.9K
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...

Sensory Perception: Organization of the Somatosensory System

8.4K
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...

Synesthesia01:27

Synesthesia

999
Synesthesia is a remarkable condition where stimulation of one sensory or cognitive pathway leads to automatic, involuntary experiences in a second sensory or cognitive pathway. People with synesthesia experience a blending or crossing of their senses, such as sight and sound, leading to cross-modal sensations. In this condition, the stimulation of one sense, such as hearing a number or musical note, triggers an experience of another sense, like sensing a specific color, taste, or smell. People...

Area of Science:

  • Neuroscience
  • Developmental Neuroscience
  • Sensory Processing

Background:

  • The nervous system distinguishes self-generated from externally-generated sensations using corollary discharges.
  • Corollary discharge gates reafferent signals, crucial for detecting novel stimuli.
  • Sensory gating may hinder early neural development by blocking essential activity.

Purpose of the Study:

  • To investigate the role of corollary discharge in processing self-generated movements during early development.
  • To test the hypothesis that twitches lack corollary discharge, treating them as unexpected stimuli.
  • To understand how the developing nervous system processes movement reafference.

Main Methods:

  • Manipulating the expectation of self-generated movements in newborn rats.
  • Assessing the processing of reafferent signals from twitches versus wake movements.
  • Examining neural responses to self-generated movements under varying conditions.

Main Results:

  • Twitches, despite being self-generated, are processed as unexpected movements.
  • Reafference from twitches reliably triggers brain activity in infant rats.
  • Vigorous wake movements fail to trigger significant reafferent brain activity under similar conditions.

Conclusions:

  • Infant rat twitches appear to lack corollary discharge, unlike other self-generated movements.
  • This unique processing of twitches may be essential for activity-dependent sensorimotor development.
  • The developing brain may treat twitches as external stimuli to maximize sensory input.
