The longer the brain has been awake, the greater the synchronous firing rates of cerebral cortex neurons. After sustained periods of sleep, both the speed and synchronicity of the neurons firing are shown to decrease. [5] Another effect of wakefulness is the reduction of glycogen held in the astrocytes, which supply energy to the neurons ...
[32] Furthermore, increasing alcohol consumption may lead to the student falling asleep faster, but facing significant sleep disturbance.
