Strabismus induces an abnormal pattern of alternating light and dark columns of cytochrome oxidase (CO) activity in macaque striate cortex. This pattern may arise because visual perception is suppressed in one eye to avoid diplopia. To test whether CO activity is reduced in the ocular dominance columns of the suppressed eye, we performed monocular enucleation to co-label the ocular dominance co...

We generated all possible haploid and homozygous diploid genotypes at 6 biosynthetic loci in yeast and scored their fitness to examine whether there was any pattern of weak synergistic epistasis, which is a requirement of the deterministic mutation model for the evolution of sex. We measured 4 components of fitness: haploid growth rate, haploid mating efficiency, diploid growth rate, and diploi...

During Binocular viewing, the preferential use of dominant eye because of its increased static ciliary muscle tone, might allow the dominant eye more myopic then non dominant eye in anisometropic myopia. However certain studies found that, there was no apparent association between ocular dominance and refraction. The present study was therefore conducted to analyze, the effect of ocular dominan...

The effect of gonadotropin releasing hormone (GnRH) treatment on the time of ovulation and the occurrence of follicular dominance during the non-breeding and breeding seasons (experiment 1), and on fertility after artificial insemination (AI) in the non-breeding season (experiment 2), was examined in Merino ewes. Oestrus was synchronized in 40 nulliparous ewes (experiment 1; n = 20, in the non-...

Aims: The aim of this study is to estimate heterosis, heterobeltiosis and dominance effect on yield, total soluble solid dry matter capia type red pepper.Methods Results: In 11 pepper parents 47 hybrids obtained from crosses these were used as materials. Heterosis in fresh fruit yield ranged -48.23 80.68. highest heterosis recorded for 209 YKB (80.68%), 239 (60.35%), 225 (56.97%) 195 (55.30%), ...

Ocular dominance (OD) has long served as the model for neural plasticity. The shift of OD has been demonstrated by monocular deprivation in animals only during early visual development. Here, for the first time, we show that perceptual eye dominance can be modulated in real time in normal human adults by varying the spatial image content of movies seen dichoptically by the two eyes over a perio...
