Effect of caffeine on central auditory pathways: An evoked potential study

Background:Caffeine is a pyschostimulant present in various beverages and known to alter alertness and performance by acting on the central nervous system. Its effects on central nervous system have been studied using EEG, evoked potentials, fMRI, and neuropsychological tests. The Stroop task is a widely used tool in psychophysiology to understand the attention processes and is based on the principle that processing of two different kinds of information (like the word or colour) is parallel and at different speeds with a common response channel.Aim:To study the effect of caffeine on classical color word Stroop task.Materials and Methods:This study was conducted on 30 male undergraduate students by performing a test before and 40 minutes after consuming 3 mg/Kg caffeine and evaluating the effect of caffeine on Stroop interference and facilitation.Results:The results revealed that practice has no effect on the performance in a Stroop task. However, there was reduction in Stroop interference and increase in facilitation after consumption of caffeine as was evident by changes in the reaction times in response to neutral, incongruent, and congruent stimuli.Conclusion:We hypothesize that caffeine led to faster processing of relevant information.

Meniere's disease is characterized by recurrent vertigo, luctuating hearing loss, and persistent tinnitus. Cafeine consumption in modern society is a widespread and culturally accepted habit; however, there is no consensus about its mechanism of action in various organs and systems, including the auditory and vestibular. The few clinical studies have shown that abstention from cafeine has litle efect in patients with Meniere's disease, both in relation to vertigo, tinnitus and hearing loss.

“…Average caffeine concentration in black tea leaves (dry) is between 20 and 50 mg (Dixit et al . ), but the caffeine in a single cup depends on different factors, namely brewing time and temperature (Labbé et al . ) and origin of tea leaves (Suteerapataranon et al .…”

Pure caffeine was dissolved in four different solvents, i.e., distilled water, ethyl acetate, chloroform and dichloromethane; further, molar decadic absorption coefficient of each solvent was determined with the help of Beer-Lambert law. It was observed that dichloromethane was the best for decaffeination as compared with the other three solvents (i.e., distilled water, chloroform and ethyl acetate). Caffeine was extracted using dichloromethane from five famous tea brands, namely Alokozay, Lipton, Tapal, Tetley and PG TIPS. The amount of extracted caffeine was quantified by employing UV-vis spectrophotometric technique. The concentration of the caffeine in the tea solution was determined at different brewing time (2, 5, 10, 15, 20, 25 and 30 min) and temperature (90 and 30C). The caffeine contents in the commercial brands (i.e., Alokozay, Lipton, Tapal, Tetley and PG TIPS) were found in the range between 1 and 5%.
