title: The impact of raising blood glucose on reaction times.
abstract: Although previous studies have demonstrated enhanced mood and memory in humans following the consumption of glucose drinks, the effect of increasing blood glucose levels on other tasks has not received the same attention. In the present study, inspection time was unaffected by glucose drinks and blood glucose levels. However, increasing blood glucose levels resulted in faster decision times when reaction time was measured. It is concluded that speed of processing is faster when the availability of glucose to the brain is increased. The possibility that the glucose-induced improvements in reaction time reflect an increased synthesis of acetylcholine is discussed.
