Can you hear your neurons firing?
Tinnitus is generated by neuron activity in the brain, researchers say. Tinnitus, that phantom ringing in the ears that affects millions of people, is generated not by the ear, but by neurons firing in the brain, according to a North American research team. “The sound is generated by neuron activity.”
What do brain zaps feel like?

Which is part of the brain promotes sleep and wakefulness?

The basal forebrain, near the front and bottom of the brain, also promotes sleep and wakefulness, while part of the midbrain acts as an arousal system.
What happens to your brain during Stage 2 sleep?
Brain wave activity slows but is marked by brief bursts of electrical activity. You spend more of your repeated sleep cycles in stage 2 sleep than in other sleep stages. Stage 3 non-REM sleep is the period of deep sleep that you need to feel refreshed in the morning.
