Most Replayed Moment: The 4 Personalities Living In Your Brain! How To Switch Between Them
Dr. Jill Bolte Taylor, a Harvard-trained neuroscientist and bestselling author, explains the four distinct "personalities" that exist within every brain based on left and right hemisphere function. She explores how trauma, addiction, and emotional reactivity map onto these personality structures, and how understanding this framework can help you recognize and switch between different mental states to feel calmer, more focused, and more in control of your responses.
