Contralateral Hand

Each cerebral hemisphere primarily controls and receives sensory input with regard to the contralateral hand. In the disconnected brain (split-brain), when the hands are uncrossed, direct visual access to each hand is available to the controlling (contralateral) hemisphere. However, when a hand crosses the midline, visual and tactile information regarding the hand are presented to different hemispheres. It is unknown how a contralateral hemi- sphere codes the position and orientation of a visually inaccessible hand in the discon- nected brain. The present work addresses this issue. We ask how each hemisphere represents “its” hand across hand positions that span the midline in the absence of cortical input from the contralateral hemisphere. In other words, when a hand is placed across the midline and is visually inaccessible, is it represented by the controlling hemisphere: (1) in accordance with its new position with respect to the body (e.g., a left hand “becomes” a right effector when it crosses the midline), (2) with left/right position information unal- tered (e.g., the left hand is represented as “left” regardless of its location), or (3) stripped of its location information altogether? The relationship between hand position and the spatial codes assigned to potential responses (an index of hand representation) was investigated in two split-brain patients using direct (Experiment 1) and orthogonal (Experiment 2) S-R compatibility paradigms. S-R compatibility effects in split-brain patients were consistent with those displayed by typical individuals. These findings suggest that position-based compatibility effects do not rely on cross-cortical connections. Rather, each hemisphere can accurately represent the full visuomotor space, a process that appears to be subserved by subcortical connections between the hemispheres.

Integration Of Learning

Five reasons are proposed why efforts to mainstream learning disabled students into the regular classroom are often unsuccessful. A mediated resource room, the Visual Response System (VRS), is described and suggested as an instructional technology which could help facilitate the integration of learning disabled students into the regular classroom. The VRS is a classroom in which each student has an overhead projector built into his or her desk. The teacher also has an overhead projector for presenting stimuli to students. Student's respond on their overhead projectors by writing, pointing, placing objects, etc. Students' responses are projected on screens behind their desks, giving the teacher immediate and continuous visual access to those responses.

Genetic Structures

The authors describe the scientific background and technical details of the visualization of the mathematics underlying genetic codes applied to musical scales. “Genetic Music” provides audible access to genetic structures that become visible based on the fundamental level of nature as permutations of space itself. The carriers of genetic information characteristically possess hydrogen bonds in quantities 2 and 3 in complementary pairs of nitrogenous bases [GACT] in DNA and [GACU] in RNA. Since hydrogen is observed to expose the symmetries of the Penrose Patterns, visual access is achieved by means of a 3D representation of Penrose kites and darts named “epitahedron.” Those pyramid-shaped polyhedra represent the numbers of hydrogen bonds (C=G=3, A=T=2) that generate musical equivalence between the genetic alphabet and the 7 notes of the Pythagorean scale, as well as further and distinct correlations with “Fibonacci stage” “Genetic Music” scales. The visualization must be played synchronously with the musical performance.

This chapter conceptualizes several aspects of digital remediations in an era of restless digital navigation. The instantaneous creation and sharing of content altering the relationship between bodies, spaces, and devices is demonstrated here. The first section of the chapter addresses various aspects of digital remediations such as screen-mediated navigations and the multifarious role of networked devices, social consequences of the intimacy between body and device, and instantaneous modes of sharing and their implications. The second segment reflects on dimensions of the post-photographic condition such as unlimited storage, ease and excess of auto-voyeuristic tendencies, publicizing the private self, death of the photographic ‘lack’, ‘fixity’, ‘nostalgia’, the witlessness/weightlessness of the visual excess, the ease of visual manipulation and the democratization of the medium, and the death of the photographer. It also briefly discusses the control and manipulation of the self-generated data.

Traditional Preparation

Before an arterial line is inserted, the skin at the site is prepped typically with the traditional iodophor-based preps. The arterial site is then covered with an occlusive dressing. When arterial lines are maintained for even a few days, it is not uncommon that some form of complication develops at the arterial site, such as redness, inflammation, positional problems, or even infection. Unfortunately, due to the nature of this traditional preparation and dressing method, the site is obscured constantly and complications are not always detected before a resulting infection occurs. This prospective study was designed to examine the efficiency and effectiveness of a new transparent prep, used with a transparent dressing at the arterial site. Sixty patients' arterial line sites were evaluated to determine the incidence of complications of the two arterial site prep and dressing methods. The effectiveness that the dressings may serve in securing the arterial lines in place was also evaluated. There were no complications in this study directly related to either skin preparation or dressing method, thus, there were no statistically significant differences. However, the transparent prep and transparent dressing method provided constant visual access to the arterial site and required fewer steps, clearly significant advantages not provided by the traditional method.
