Tactile extinction and functional status after stroke. A preliminary investigation.
BACKGROUND AND PURPOSE Research has identified a number of factors associated with poststroke recovery, but the prediction of long-term functional outcome remains an uncertain endeavor. In previous work, extinction to tactile, double-simultaneous stimulation has been shown to have short-term predictive utility. The present study was designed to examine its long-term prognostic value and to dete...
متن کاملLeft tactile extinction following visual stimulation of a rubber hand.
In close analogy with neurophysiological findings in monkeys, neuropsychological studies have shown that the human brain constructs visual maps of space surrounding different body parts. In right-brain-damaged patients with tactile extinction, the existence of a visual peripersonal space centred on the hand has been demonstrated by showing that cross-modal visual-tactile extinction is segregate...
متن کاملElectrostatic Tactile Display Using Beat Phenomenon for Stimulus Localization
We present an electrostatic tactile display for stimulus localization. The 240-Hz electrostatic force was generated by the beat phenomenon in a region where excited X electrodes cross excited Y electrodes, which presents localized tactile sensation out of the entire surface. A 10.4in. visual-tactile integrated display was successfully demonstrated. key words: tactile display, electrostatic forc...
متن کاملBinding personal and peripersonal space: evidence from tactile extinction.
Behavioral and neurophysiological studies suggest that the brain constructs different representations of space. Among these representations are personal and peripersonal space. Personal space refers to the space occupied by our bodies. Peripersonal space refers to the space surrounding our bodies, which can be reached by our limbs. How these two representations are bound to give a unified sense...
متن کاملThe influence of limb crossing on left tactile extinction.
BACKGROUND Previous research on patients with left tactile extinction has shown that crossing of hands, so that each hand is on the opposite side of the body midline relative to the other, improves detection of stimuli given to the left hand. OBJECTIVES To study the influence of the spatial position of limbs on left tactile extinction, and its relations with left visual neglect. METHODS Nor...
