When any of us make decisions, our brains go through a six-stage cycle. Before the novel stimuli shows up (which is what starts the whole process), we’re in a baseline state. Then we move to problem-solving analysis, pre-action readiness, action, post-action evaluation, and back to baseline. Each of these stages requires different parts of the brain and produces different brain waves: theta for processing novel stimuli, beta for analysis, alpha for action, etc.
