Visuo-spatial inattention (VSI) was examined in 390 patients with ischemic insult to the right or left cerebral hemispheres. VSI was revealed in 44 out of 80 patients with right parietal lobe damage and in 30 out of 70 subjects with right occipital lobe injury. Only one patient out of 100 with left hemisphere injury has shown the signs of VSI. These data(More)
In this review the modern concepts on psychophysical mechanisms of hemispheric functional specialization of human visual perception are considered. The problems are discussed on three basic historical aspects: interhemispheric relations in patients with localized cerebral lesions, interhemispheric differences in the "Bisected Brain", and the functional(More)
Paired stimulation of callosal neurons in the lateral gyrus causes inhibition of the second EP in every part of the cortex with callosal connections. Paired stimulation of callosal neurons in the suprasylvian gyrus causes facilitation of the second EP in the contra- as well as ipsilateral cortex. The possible role of recurrent collaterals in brain(More)
Activity of 28 identified neurones of the visual cortex was recorded in cats immobilized by d-tubocurarine. Stimulation of the callosal body with a single stimulus or high-frequency train elicited a short-latency antidromic reaction of neurones in the visual cortex whose axons constitute the main part of the large cerebral commissure. Some commissural(More)
For the last 15-20 years the study of interhemispheric relations made a big progress. This progress was facilitated by use of new methods in combination with midsagittal sections of comissural connections at different levels. An assumption is made that interhemispheric exchange of sensory information is of certain importance for the short-term memory and(More)
In anesthetized cats, antidromic and orthodromic components were shown to be represented unequally in the mixed responses to the splenium stimulation recorded from various areas of the cortex. Orthodromic component makes about 50 per cent of the mixed response amplitude in the area 17, while in the area 18 and in middle part of the suprasylvian gyrus it(More)
