The Dream of Television

Brainwaves come from cells in about the top ¼” of the cerebral cortex. Brainwaves come from millions of cells working together. The brain has over 100 billion cells. The EEG is like a symphony, which is a complex mixture of sounds changing in time and place. An EEG machine is just a computer with a couple of wires touching the head and a little amplifier.
EEG’s are read in frequency bands. The brainwaves from slowest to fastest are called: delta, theta, alpha, beta and gamma. The brain signals are related to alertness, level of attention, and degree of mental effort.
Dr. Collura describes some of the current beliefs about the meanings of brain waves. Delta happens mostly during a deep sleep. Lots of theta is imagination, and little theta is concentration. Alpha is relaxed but not sleepy. High beta is strong with mental activities like math and planning, but may also mean being anxious. Gamma is thinking hard about different things at the same time.
Dr. Collura said: “Reducing theta brain waves while simultaneously raising alpha waves enhances concentration resulting in:
1) reduction of errors;
2) greater attention to detail;
3) increased self control;
4) sustained attention to tasks;
5) ability to shut off environmental distractions.”
I can conclude that my hypothesis is true. I can tell the brainwaves apart for different tasks. I also conclude that playing cello uses more of my brain than doing homework, and watching TV is like sleeping. ´

What are Theta Brainwaves?
"Theta activity is defined by international Federation of Electrophysiology and Clinical Neurophysiology as a frequency band of 4-8 mHz."
"Theta Brainwavesengage inner and intuitive subconscious. You’ll find theta in places where you hold memories, sensations and emotions. Sometimes, we also store secrets there, which we block out in times of pain, to survive what we feel unprepared to fix."

Theta (upper case , lower case ) is the eighth letter of the Greek alphabet. In the system of Greek numerals it has a value of 9.
The letter is an abbreviation for the Greek word thanatos (: "death"; see Thanatos and Thanatology) and as it vaguely resembles a human skull, was occasionally used by Greeks as a warning symbol for death, in much the same way that skull and crossbones are used today.
More about the Greek alphabet
In Greek mythology, Thanatos (, "death") was the personification of death (Roman equivalent: Mors). He was a creature of bone-chilling darkness. He was a son of Nyx and twin of .
Thanatos might be poetically called the brother of Sleep and the son of Night.
In psychoanalytical theory, Thanatos is the death instinct, which opposes Eros. The "death instinct" identified by Sigmund Freud, which signals a desire to give up the struggle of life and return to quiescence and the grave.
Thanatology is the scientific study of death.
