Abstract Introduction: Mobile phones create high-frequency electromagnetic fields around them when in use. The close proximity of mobile phones to the user’s head leads to the absorption of part of the electromagnetic waves into the head and the brain. Methods: We have elucidated the alteration in cognitive function of the male and female offspring rats, which were exposed to chronic mobi...

Certain species of orb-weavers add extra silk structures, termed a stabilimentum or web decoration, to their webs. In the genus Argiope stabilimenta are silken structures of densely woven zig-zag ribbons. The adaptive value of these stabilimenta is still unclear and controversially discussed. In the course of time, many functional hypotheses have been proposed for silk stabilimenta. Because of ...

The anxiolytic activity of Ocimum sanctum leaf extract was studied in mice. O.sanctum leaf extract produced significant anxiolytic activity in plus - maze and open field behaviour test models. The effect was compared with diazepam, a standard antianxiety drug.

Introduction: In the quest for search of novel pharmacotherapy from medicinal plants psychiatric disorders, it has progressed appreciably past few decades and their therapeutic potential been evaluated in a variety murine models. Cassia singueana Del. is commonly used plant Nigeria management insanity as lactation enhancer. Aim: The main aim this study was to evaluate cognitive extract against ...

Inbred strains of mice are known to differ in their performance in the Morris water maze task, a test of spatial discrimination and place navigation in rodents, but the genetic basis of individual variation in spatial learning is unknown. We have mapped genetic effects that contribute to the difference between two strains, DBA/2 and C57BL6/J, using an F2 intercross and methods to detect quantit...

A disconnection procedure was used to test whether the hippocampus and anterior thalamic nuclei form functional components of the same spatial memory system. Unilateral excitotoxic lesions were placed in the anterior thalamic (AT) nuclei and hippocampus (HPC) in either the same (AT-HPC Ipsi group) or contralateral (AT-HPC Contra group) hemispheres of rats. The behavioral effects of these combin...

Although the cognitive and biological characteristics of Alzheimer's disease (AD) are well known and mouse models of AD are available, current treatments for AD-related cognitive deficits have quite limited efficacy. The development of tasks with cross-species validity may enable better prediction of the efficacy of potential new treatments. In this issue of the JCI, Possin et al. present a vir...

The basic idea of the method [1] is best demonstrated with a simple problem that already is given in terms of paths. Fig. 1 depicts how we can solve a typical maze problem. The maze is equipped with mirrors so that light entering the maze simultaneously runs through all possible paths. Interference will be detected if the optical path lengths (OPD) of the two interferometer arms are equal. Ther...

Augmented Reality (AR) technology is sufficiently mature, where it is possible to evaluate improvement in human performance. A critical aspect of human performance is individual differences in AR. In the present study, the effect of gender on human performance in a “search and rescue” navigation task is assessed. Six conditions were investigated in the study: Two control conditions (paper map o...

This study examines possible interactions between behavioral effects and influence of N-methyl-D-aspartate acid (NMDA) receptors in 4 and 12-week streptozotocin (STZ) induced diabetic rats. Effects of NMDA receptor agonist on spatial learning were tested in control groups of rats and in rats with 4 and 12 weeks diabetes mellitus (DM). Experimental diabetes was induced by a single intravenous in...
