Somatosensation01:33

Somatosensation

36.5K
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

2.9K
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...

Sensory Functions of the Skin01:16

Sensory Functions of the Skin

4.9K
The skin is the largest organ of the human body and plays a crucial role in our sensory perception. It contains a vast network of sensory receptors that contribute to the skin's protective function by perceiving physical, biological, and environmental cues and generating relevant responses.
There are two main categories of receptors on the skin: capsulated and non-capsulated. The non-capsulated ones are mainly the pain receptors. The capsulated ones can be further categorized based on the...

Design Example: Resistive Touchscreen

303
A device engineer plays a crucial role in designing user interfaces for mobile devices. One such interface is the resistive touchscreen, which fundamentally consists of two metallic layers: a flexible upper layer and a rigid lower layer, separated by a narrow gap. The high resistance between these two layers is a key characteristic of this design.
When a user touches the screen, the two layers make contact at a specific point known as the touchpoint. This contact reduces the resistance between...

Overview of Somatic Sensory Pathways01:29

Overview of Somatic Sensory Pathways

4.3K
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...

    Area of Science:

    • Biomedical Engineering
    • Neuroscience
    • Rehabilitation Technology

    Background:

    • Loss of touch sensation from conditions like diabetes or stroke lacks effective treatments.
    • Haptic sensory prostheses offer potential for restoring lost tactile feedback.
    • The wrist and forearm are suitable locations for sensory feedback devices.

    Purpose of the Study:

    • To investigate the efficacy of spatial summation using multiple pressure points for haptic feedback.
    • To improve the range of stimulus intensity in sensory prostheses.
    • To enhance the perception of tactile feedback for individuals with sensory loss.

    Main Methods:

    • Developed a haptic sensory prosthesis prototype.
    • Focused on localized pressure as the feedback modality.
    • Conducted a preliminary perceptual test comparing one vs. two pressure points.

    Main Results:

    • Spatial summation, using multiple pressure points, was explored as a feedback method.
    • The just noticeable difference (JND) was reduced with two points of pressure compared to one.
    • This finding supports the hypothesis that spatial summation can improve tactile feedback.

    Conclusions:

    • Multiple pressure points can enhance tactile perception through spatial summation.
    • This approach holds promise for improving future sensory prostheses.
    • Further research is warranted to integrate spatial summation into functional sensory substitution devices.
