Abstract

It has been shown that physical exercise is beneficial for cognition, however, the neuronal mechanism underpinning this process is not yet clear. In a study examining the immediate effects of physical exercise on long-term memory, we aimed to investigate the correlation of brain activity during physical exercise with memory performance. Healthy adult participants (n = 18) were asked to memorise a set of 80 stimuli. Subsequently, they were asked either to cycle on an exercise bike for ~30 minutes (2 minutes of warm-up + 6 blocks of 4-minute cycling 1-minute rest) while their EEG was recorded, or to sit on the exercise bike comfortably and watch a documentary for 30 minutes. After a 1.5 hour retention interval period, they were shown 160 stimuli (80 old and 80 new) and were asked to perform an old/new recognition task. The behavioural data showed an improvement in memory performance (exercise 71.11% vs. rest 66.67%, p=0.02). More importantly, the theta band oscillatory activity of an electrode over the dorsolateral prefrontal cortex (DLPFC) was negatively correlated with the enhanced performance (r=-0.48, p=0.04). Results highlight the modulatory effect of physical exercise on neuronal activity and a functional role of theta activity in memory enhancement during consolidation.
