The corpus callosum (CC) is a brain structure composed of axon fibres linking the right and left hemispheres. Musical training is associated with larger midsagittal cross-sectional area of the CC, suggesting that interhemispheric communication may be faster in musicians. Here we compared interhemispheric transmission times (ITTs) for musicians and non-musicians. ITT was measured by comparing si...

The human auditory cortex is the gateway to the most powerful and complex communication systems and yet relatively little is known about its functional organization as compared to the visual system. Several lines of evidence, predominantly from recent studies, indicate that sound recognition and sound localization are processed in two at least partially independent networks. Evidence from human...

After exposure to asynchronous sound and light stimuli, perceived audio-visual synchrony changes to compensate for the asynchrony. Here we investigate to what extent this audio-visual recalibration effect transfers to visual-tactile and audio-tactile simultaneity perception in order to infer the mechanisms responsible for temporal recalibration. Results indicate that audio-visual recalibration ...

The present study was designed to assess the effects of the Transcendental Meditation (TM) program on strength of the nervous system, perceptual reactance, reaction time, and auditory threshold. Three reaction time indices of strength of the nervous system were utilized: 1) Nebylitsyn's index, 2) the slope index, and 3) the low level stimulation index. Absolute auditory threshold was the fourth...

OBJECTIVE To evaluate the influence of menstrual cycle on auditory and visual reaction times. METHOD This study was conducted on thirty, healthy, regularly menstruating female subjects who were in the age group of 18-25 years. Influence of different phases of menstrual cycle on Auditory Reaction Time (ART) and Visual Reaction Time (VRT) was evaluated by using a portable audiovisual reaction t...

it is not known whether the instincts of wild horses have remained strong during their centuries of domestication. knowledge of this matter would give riders the opportunity to know more about the behavior of horses and consequently about safety for both horses and riders. in this current research, we studied the behavior of fifteen caspian miniature horses of different ages and sexes using sti...

Background: Personality traits along with well-known factors like socioeconomic status and cognitive ability, predict important life outcomes such as health lifespan, educational occupational attainment, may promote specific types of task effectiveness, which occurs in part via the processing information. Reaction time provides an indirect index central nervous system’s integrity ability. Mater...
