Delta waves indicate the slowest type of brain activity. These rhythms are seen during deep sleep.
In terms of activity, Theta waves fall between Delta and Alpha. They are characteristic of someone who is drowsy or in light sleep. They can also be produced by someone who is hypnotized, day dreaming, or lucid dreaming.
These brain-waves are characteristic of normal consciousness. When you are awake, your brain is probably producing alpha waves.
Beta waves are seen when a person is very active, under stress or concentrating hard on a task. They are high frequency waves and indicate that the brain is working hard.
In a different study, sleep-deprived volunteers were given mental reaction tests. They were then instructed to either take a short nap or meditate. They were then retested. The volunteers who meditated showed superior performance on the tests, even though they had no prior experience with meditation.
There are two possible reasons for the memory decline experienced by smokers. The first is that smoking damages the lungs and constricts the blood vessels. This decreases the amount of oxygen that can get to the brain, which causes the brain to function at decreased efficiency and can cause some damage. The second reason is that smoking can cause hypertension which can damage the tiny blood vessels that feed the neurons in the brain. Without proper blood flow, the neurons will become damaged. The good news is that quitting smoking can reverse the decline and improve memory performance.
