My Stroke of Insight: A Brain Scientist's Personal Journey

by Jill Bolte Taylor

Most of the different types of cells in our body die and are replaced every few weeks or months. However, neurons, the primary cell of the nervous system, do not multiply (for the most part) after we are born. That means that the majority of the neurons in your brain today are as old as you are. This longevity of the neurons partially accounts for why we feel pretty much the same on the inside at the age of 10 as we do at age 30 or 77. The cells in our brain are the same but over time their connections change based upon their/our experience.

The portion of my left mind that I chose not to recover was the part of my left hemisphere character that had the potential to be mean, worry incessantly, or be verbally abusive to either myself or others. Frankly, I just didn’t like the way these attitudes felt physiologically inside my body. My chest felt tight, I could feel my blood pressure rise, and the tension in my brow would give me a headache. In addition, I wanted to leave behind any of my old emotional circuits that automatically stimulated the instant replay of painful memories. I have found life to be too short to be preoccupied with pain from the past.

To counter their activities, I keep a handy list of three things available for me to turn my consciousness toward when I am in a state of need: 1) I remember something I find fascinating that I would like to ponder more deeply, 2) I think about something that brings me terrific joy, or 3) I think about something I would like to do. When I am desperate to change my mind, I use such tools.
