What makes a frontal area of primate brain the frontal eye field?

The frontal eye field region (FEF) of the oculomotor pathways has been intensely studied. The primary goal of this review is to illustrate the phylogenetic displacement of the FEF locus in primate species. The locus is arrayed along the arcuate sulcus in monkeys and abuts into the primary motor strip region in humans.

Muscle strength and body composition in adult women with Marfan syndrome.

Objective: The purpose of this study was to assess skeletal muscle function and body composition in a group of women with Marfan syndrome compared with matched controls.

Methods: The 21 women who were receiving follow-up for Marfan syndrome at our institution, were free of major cardiovascular disease, and consented to the study performed isokinetic and isometric knee extension and flexion maximal strength tests and had their body composition evaluated using dual-energy X-ray absorptiometry (DEXA). The same assessments were done in 19 matched controls.

Effect of 1-year oral administration of dehydroepiandrosterone to 60- to 80-year-old individuals on muscle function and cross-sectional area: a double-blind placebo-controlled trial.

Background: The age-related decline of dehydroepiandrosterone and its sulfate ester levels is thought to be related to the development of age-associated usual modifications, such as neuromuscular function impairments. It is often claimed that individuals can enhance their muscular capacity by boosting dehydroepiandrosterone levels through oral supplementation. However, to our knowledge, there have been no controlled studies on a significant number of individuals demonstrating positive effects on the neuromuscular system.

A reliable system of ventricular coordinates for the cartography and stereotaxy of the amygdala (and anterior hippocampus) in macaques.

The most reliable stereotactic methods in primates resort to ventricular as opposed to bony landmarks. The usual CA-CP system did not appear satisfactory for stereotaxy of the amygdala and anterior hippocampus. Variation studies on ventriculograms and reconstructions from histological material were done to find more reliable systems.
