Overestimation of numerical distances in the left space

2004

Normal subjects presented with a middle number and two left- and right-sided outer numbers overestimate the numerical distance between the middle number and that positioned at its left side. Repetitive transcranial magnetic stimulation (rTMS) of the right posterior parietal cortex specifically counteracts this bias, suggesting that the mental representation of space defined by numbers is shifted toward the left side depending on a greater activity of the right hemisphere.

Occurrence and regional distribution of striated muscle fibers in the rat pineal gland

1978

In a total of 96 rat pineals studied 31 were found to contain striated muscle fibers or their precursors. The muscle fibers were most frequently present in the stalk region and more frequently found in the left than in the right hemisphere. Size measurements revealed that the lengths of pineal muscle cell nuclei differ only slightly from those of the sphincter muscle of the iris. However, the yellowish appearance of pineal muscle cell nuclei under darkfield investigation, a phenomenon observed in all muscular tissues of mesenchymal origin and connective tissue cells, may support the hypothesis that pineal musculature is of mesenchymal rather than ectodermal origin.

Dichotic listening: elimination of the right ear advantage under a dual task procedure.

1997

The aim of this article is to investigate the attentional effect on the dichotic listening (DL) performance when doing a simultaneous right hemisphere task. A group of 30 right-handed male participants had a standard DL test followed by a dual task procedure that consisted of a manipulospatial discrimination through the left hand and performed while doing the DL test. Participants showed the typical right ear advantage (REA), which lost its significance when they were confronted with the dual task, presumably due to the manipulospatial performance. The elimination of the REA was mainly due to facilitation of the left ear responses. Results are discussed in terms of Kinsbourne's model and ot…
