Consciousness may have developed through evolution as perhaps a little forethought and planning may have been valuable in survival. Consciousness is from the activity in distributed networks of neural pathways. Electroencephalograph (eeg): a device that monitors the electrical activity of the brain over time by means of recording electrodes attached to the surface of the scalp, in terms of brain waves. Biological rhythms: periodic fluctuations in physiological functioning; these mean than organisms have internal biological clocks that monitor the daily alternation of light and darkness, annual pattern of the seasons, and phases of the moon. Circadian rhythms: 24 hour biological cycles found in humans and many other species; used in regulation of sleep particularly, also rhythmic variations in blood pressure, urine production, hormonal secretion, and other physical functions like alertness, short-term memory etc.
