Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2018, Vol 17, Issue 5
Abstract
Reaction time is the measure of the function of sensory motor association. and performance of an individual . Reaction time is the time required for the nervous system to receive, integrate the incoming sensory information and cause the body to respond.. Caffeine belong to Xanthene group of drugs. Caffeine is a central nervous system stimulant that reduces fatigue and drowsiness, at normal doses, caffeine has variable effects on learning and memory. The aim of the study was to determine visual reaction time (VRT) for green (G) verses red (R) color light and auditory reaction time (ART) in young adults after the administration of known amount of caffeine. A cross-sectional study was carried out in 40 male medical students in the age group of 18-20 years from Sri Deva raja Urs Medical College in the Department of Physiology. The reaction time was measured by using an indigenously designed portable apparatus called as the reaction time apparatus. The auditory reaction time was found to be less than visual reaction time, Many researchers have confirmed that reaction to sound is faster than light with mean auditory reaction time being 140-160 ms and visual reaction time being 180-200ms. Hence can be concluded that reaction time for sound is less than light and also that caffeine is a strong central nervous system stimulant.
