Awareness of internal and external thoughts stream of consciousness- william james. Briefly discuss why we need consciousness: we need it because behaviour is the result of our conscious thoughts.

Electroencephalograph. a device that monitors the electrical activity of the brain over time by means of recording electrodes attached to the surface of the scalp. records our sleep pattern. Briefly discuss brain waves (amplitude vs frequency; beta, alpha, theta, delta): Eeg summarizes the rhythm of cortical activity activity in the brain in terms of line tracings called brain waves. Beta: normal waking thought and alert problem solving. What are biological rhythms? periodic fluctuations in physiological functioning. Biological clocks that monitor the passing of time. Humans, like most animals and plants, have biological rhythms, known as circadian rhythms, which are controlled by a biological clock and work on a daily time scale.
