Role of the somatosensory system in primary dystonia
Movement Disorders, 2003AbstractThe pathophysiology of dystonia is still not fully understood, but it is widely held that a dysfunction of the corticostriatal–thalamocortical motor circuits plays a major role in the pathophysiology of this syndrome. Although the most dramatic symptoms in dystonia seem to be motor in nature, marked somatosensory perceptual deficits are also ...

The somatosensory system has by far the largest number of receptor types of any of the primate sensory systems, including mechanoreceptors, chemoreceptors, nociceptors and thermoreceptors. The sensation of touch is mainly mediated by mechanoreceptors, but there are a number of other processing channels within the somatosensory system for proprioception,

The Role of the Somatosensory System in General Electroanesthesia
Anesthesia & Analgesia, 1974The effects of peripheral nerve block or severance on the course of externally applied general electroanesthesia (EA) was studied in 6 Rhesus monkeys. The baseline minimum current requirement for general EA at several frequencies was initially established for each monkey.

The somatosensory cortex in multiple system atrophy
Journal of the Neurological Sciences, 2008In multiple system atrophy (MSA), it has been accepted that the motor-related cortical area may degenerate. However, there have been few investigations of the postcentral cortex of the somatosensory area. For this reason, we investigated the effects of MSA on both the precentral and the postcentral cortex and were able to demonstrate degenerative ...

This chapter explains that skin is the interface between the body and the outside world. Skin is not uniformly sensitive over its surface. The chapter analyses the punctate distribution of various sensations: specific points of the skin are sensitive to touch, others are sensitive to cooling, warming, or noxious stimuli.

Evidence for a unimodal somatosensory attention system
Experimental Brain Research, 2003Extinction is generally viewed as a disorder of selective attention for spatial locations. Recent physiologic, behavioral and lesion studies view spatial locations as a complex construct in which multiple modalities and motor systems are integrated. Accordingly, cross-modal and sensory-motor conditions often modify extinction. In a patient with tactile

Apparent redundancy in the somatosensory system in monkeys
Experimental Neurology, 1972Abstract Monkeys were used for recording the cortical responses to electrical stimulation of the superficial radial nerve skin territory. High cervical section of fasciculi gracilis and cuneatus, with or without concurrent lesions of the spinocervical tract, did not modify the cortical evoked responses.

Neuronal adaptation in the somatosensory system of rodents
Neuroscience, 2017The sensory systems in animals constantly monitor the environment and process salient and relevant features while subtracting background activity. This process requires continuous recalibration of neuronal gain based on recent history. Adaptation has been postulated to be the key mechanism by which neurons rapidly tune their response curves to ...

Somatosensory system excitability in migraine
Paediatrics and Child Health, 2009Abstract Migraine is a common disorder that reduces normal day-to-day activities, including those connected with work. While migraine has long been considered a disease of the head vascular structures, there is increasing evidence that the somatosensory system plays a primary role in the cascade of events that trigger the migraine attacks and in its ...

Publisher Summary This chapter discusses the specific features of the somatosensory system. This includes the anatomical organization of the classical and the nonclassical somatosensory systems, followed by discussions of the physiology of these systems. The somatosensory system provides information about touch, vibration, temperature of the skin, and
