Effect of Variation of Spatial and Temporal Frequencies of the Moving Field Visual Stimulus on Optokinetic Response of Adult Zebrafish.

The optokinetic response (OKR) is a reflexive behavior in which the eye intends to fixate the surrounding image in motion on its retina. The two important components of the OKR visual stimulus are the spatial frequency (SF) and the temporal frequency (TF). Zebrafish () is considered an important model animal for visual physiology research.

Assessment of nutritional status using anthropometric variables by multivariate analysis.

Background: Undernutrition is a serious health problem and highly prevalent in developing countries. There is no as such confirmatory test to measure undernutrition. The objective of the present study is to determine a new Composite Score using anthropometric measurements.
