1. Terminology The term split-brain has several meanings. Applied to the human, it denotes complete sectioning of the corpus callosum, an operation which is usually performed for medically intractable, multifocal epilepsy (Reeves and Roberts, 1995). In the experimental animal, such as the cat or monkey, it usually implies both callosal section and a split optic chiasm; this makes it possible to...

The split closure has been proved in practice to be a very tight approximation of the integer hull formulation of a generic mixed-integer linear program. However, exact separation procedures for optimizing over the split closure have unacceptable computing times in practice, hence many different heuristic strategies have been proposed in the last years. In this paper we present a new overall fr...

Integrating dynamic information across the senses is crucial to survival. However, most laboratory studies have only examined sensory integration for static events. Here we demonstrate that strong crossmodal integration can also occur for an emergent attribute of dynamic arrays, specifically the direction of apparent motion. The results of the present study show that the perceived direction of ...

We present a case study in the use of performance modeling for parallel application development, with a biological cell simulation as our target application. We show that a simple performance model is adequate for determining data layout for arrays and linked structures, and validate our model against experimental results for some application kernels. We quantify the importance of optimizing ac...

It was proposed that split-brain monkeys are able to perform ipsilateral eyehand response because the seeing hemisphere can cross-cue the blind hemisphere, which is in major motor control of the arm, by orienting toward a point in space and, thereby, allow for the bilateral registration of head, neck, and eye position. In the present study, accuracy of ipsilateral eye-hand response was measured...
