The right hemisphere advantage for split-brain patients on a variety of spatial tasks (block design, cube drawing, wire figures, and fragemented stimuli) is found to be highly dependent upon the involvement of manual activities in the perception of spatial relationships or the production of spatial responses. The cerebral localization of the neural substrate of manipulo-spatial functions sugges...

As part of a large-scale study of menstrual blood loss in the community serum fibrin degradation products were measured soon after menstruation in 331 women. No significant correlation was found between the amount of blood lost and the serum level of fibrin degradation products. These findings conflict with reports suggesting that excessive intrauterine fibrinolysis, which may play a part in me...

An illustrated key is provided to distinguish the 34 species of genus Thrips reported from the Afrotropical Region, including La Réunion. Seven new synonyms are established as a result of checking type specimens; two new species are described, T. solari from Nigeria and T. kurahashii from South Africa; and the new combination Craspedothrips ghesquierei (Priesner) is established for a species de...

Recent neurophysiological research in the monkey has revealed bimodal neuronal cells with both tactile receptive fields on the hand and visual receptive fields that follow the hands as they move, suggesting the existence of a bimodal map of visuotactile space. Using a cross-modal congruency task, we examined the representation of visuotactile space in normal people and in a split-brain patient ...

In this paper we present a concept of dual human information processing as an aid to understanding the decision styles and decision strategies o f managers. Several threads of thought are woven together: neurological studies of “split-brain” persons, Jung’s typology of personality, and philosophical explanations of human duality. The resulting framework differentiates a range of leftto right-he...

Until recently, most neuroscientists did not regard consciousness as a suitable topic for scientific investigation. This reluctance was based on certain philosophical mistakes, primarily the mistake of supposing that the subjectivity of consciousness made it beyond the reach of an objective science. Once we see that consciousness is a biological phenomenon like any other, then it can be investi...

An important procedure in the mathematics of phylogenetic analysis is to associate, to any collection of weighted splits, the metric given by the corresponding linear combination of split metrics. In this note, we study necessary and sufficient conditions for a collection of splits of a given finite set X to give rise to a linearly independent collection of split metrics. In addition, we study ...

A commissurotomy patient and two neurologically intact control observers were required to encode spatial patterns presented concurrently to the two hemifields. Under conditions of maximal perceptual load, in which different patterns appeared in the two fields, the commissurotomy patient encoded more information than the control observers. Based on these findings, it is concluded that competitio...
