One view: synchronized, coordinated brain activity generates consciousness/or a sign that conscious activity is occurring. Conscious vs. unconscious activity - the dual-track mind: Conscious (cid:862)high(cid:863) track: our minds take deliberate actions we know we are doing; examples: problem solving, naming an object, defining a word. Unconscious (cid:862)low(cid:863) track: our minds perform automatic actions, often without being aware of them; examples: walking, acquiring phobias, processing sensory details into perceptions and memories. One study showed students showed brain activity related to pushing a button before they were aware of their decision to push the button.
