Representation of orientation in the somatosensory system
Behavioural Brain Research, 2002In this paper we discuss how orientation is represented and transformed in the somatosensory system. Information about stimulus orientation plays an important role in sensory processing. In touch it provides critical information about how stimuli are positioned on the hand, which is important for grasping and lifting objects. It also provides important

The Specific Somatosensory System and Dyskinesia
Archives of Neurology, 1968SEVERAL hypotheses have been proposed for the mechanism of abnormal movements, with the greatest emphasis placed upon the role of central structures. 1-3 While the importance of muscle afferents has also been stressed, 4 little attention has been paid to other peripheral receptors.

Sensing and deciding in the somatosensory system
Current Opinion in Neurobiology, 1999Combined psychophysical and neurophysiological experiments have revealed some of the neural codes associated with perception and processing of tactile information. Recently, intracortical microstimulation was used to demonstrate a causal link between primary cortical activity and perception.

Sensory information from body tissues such as the skin, muscles, joints and viscera reaches, the brain via two distinct routes represented by the lemniscal system and the extralemniscal or anterolateral system. Together these two pathways form the somatosensory afferent system.

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 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 ...

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.

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
