Document Summary

Rapid eye movements during sleep has a connection with dreams. Rapid eye movement sleep blossomed into a number of other fascinating insights about what goes on in the brain during sleep. Conscious and unconscious processes are different levels of awareness (sigmend freud) Research shows that people continue to maintain some awareness during sleep and even when they are put under anesthesia for surgery. The evolutionary roots of consciousness consciousness allowed our ancestors to think through courses of action and their consequences evolutionary bases of consciousness remain indefinable. Consciousness and brain activity consciousness does not arise from any distinct structure in the brain but rather from activity in distributed networks of neural pathways. Electroencephalograph(eeg) summarizes the rhythm of cortical activity in the brain in terms of line tracings called brain waves. Brain wave activity divided into 4 brands: beta (13-24 cps), alpha (8-12 cps), theta (4-7cps), and delta (under 4 cps).
