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.

Secondary Spinal Cord Injury llI: Pathophysiology

Early Ischemia and Ionic ImbalanceWithin minutes of spinal cord injury, a secondary cascade begins, progressing over hours to weeks. Vascular damage reduces blood flow, causing ischemia and mitochondrial dysfunction. ATP depletion leads to ion pump failure, membrane depolarization, sodium influx, potassium efflux, and water accumulation, resulting in cellular swelling. Increased intracellular calcium further disrupts mitochondria and accelerates cellular injury.Excitotoxicity and Neuronal...

Summary

This summary is machine-generated.

Stroke survivors with poorer motor function show reduced sensory pathway processing. Position-cortical coherence (PCC) may help understand motor recovery mechanisms after stroke.

Neuroscience
Rehabilitation Medicine
Biomedical Engineering

Background:

Stroke recovery hinges on intact motor and sensory pathways.
Assessing sensory pathway function post-stroke is crucial for predicting motor function recovery.

Purpose of the Study:

To evaluate afferent sensory pathway information transfer and processing after stroke.
To investigate the relationship between sensory processing and motor function in subacute stroke survivors using position-cortical coherence (PCC).

Main Methods:

Eleven subacute stroke survivors performed motor tasks with applied wrist position perturbations.
Electroencephalography (EEG) measured cortical activity.
Position-cortical coherence (PCC) calculated between perturbations and EEG signals in sensorimotor areas.

Main Results:

All subjects demonstrated significant contralateral PCC for both affected and non-affected wrists.
Reduced presence of contralateral PCC was observed in stroke survivors with poorer motor function during affected wrist tasks.
The amplitude of significant PCC did not differ between good and poor motor function groups.

Conclusions:

Poorer motor function in subacute stroke is associated with diminished sensory pathway information transfer and processing.
Position-cortical coherence (PCC) shows potential as a biomarker for assessing sensory processing deficits and predicting motor recovery after stroke.
