Introduction: Caffeine is a Psychostimulant consumed as natural components in chocolates, coffees and teas, and as added components to soda, energy drinks, and some drugs. It has been reported to impair the brain in several ways that might lead to activity breakdown. Aim: The present study therefore investigated the potency of caffeine on the neurobehavior and histomorphology of the frontal cortex of a murine model. Materials and Methods: Thirty albino mice were divided into five groups (n = 6), administered intraperitoneally 0.2 ml distilled water, 25, 30, 40 and 60 mg/kg body weight (bw) of caffeine, respectively for 14 days, while the bws were measured prior and after the experiment. On day 15, the dark and light field behavioral test was carried out and the animals were sacrificed by, perfusion method, and the frontal cortices excised from whole brains and routinely processed for histological studies. Results: The mice gained bw in the 25 and 30 mg/kg bw caffeine groups, but lost weight in the 40 and 60 mg/kg bw caffeine groups. No difference was observed in the entire light and dark field test parameters, while histological studies showed significant (P < 0.05) hyperplasia of the frontal cortical cells in the caffeine test groups, all compared with the control and among the test groups. Conclusion: Consumption of the given low dose of caffeine, caused gain in weight while high dose of caffeine caused bw loss, but did not affect the dark and light field behavioral parameters, but stimulated frontal cortical cell hyperplasia possibly as a protective measure.
