Dependence of reaction time on visual fields in patients with unilateral hemispheric lesions.
Reaction times (RTs) to light stimuli which appeared at central and lateral positions were measured in 13 normal subjects and 34 patients with unilateral lesions in the left or the right hemisphere. The normal subjects showed slowing of RTs to both lateral stimuli compared to the central stimulus, the extent of which was equal between the left and right hands. The patients with left hemispheric...
متن کاملDirect and Indirect Timing Functions in Unilateral Hemispheric Lesions
Introduction: The neural substrates of temporal processing are not still fully known. The majority of interval timing studies have dealt with this subject in the context of “Explicit timing” (computing the time intervals explicitly). The hypothesis “Implicit timing” (implicitly using temporal processing to improve function) has also proposed. This lesion study addressed explicit and implicit ti...
متن کاملCrossed hemispheric diaschisis in unilateral cerebellar lesions.
BACKGROUND AND PURPOSE We studied 12 patients with unilateral cerebellar hemorrhage to look at its effect on regional cerebral blood flow. METHODS We used single-photon emission computed tomography by continuous inhalation of xenon-133. The blood flow was quantified in the cerebellum and in nine areas of interest on the slice passing through the basal ganglia. RESULTS The comparison of the ...
متن کاملSound lateralisation in patients with left or right cerebral hemispheric lesions: relation with unilateral visuospatial neglect.
OBJECTIVES To localise the brain lesion that causes disturbances of sound lateralisation and to examine the correlation between such deficit and unilateral visuospatial neglect. METHOD There were 29 patients with right brain damage, 15 patients with left brain damage, and 22 healthy controls, who had normal auditory and binaural thresholds. A device was used that delivered sound to the left a...
