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

by Jill Bolte Taylor

The cells in our brain are the same but over time their connections change based upon their/our experience.

Although each hemisphere is unique in the specific types of information it processes, when the two hemispheres are connected to one another, they work together to generate a single seamless perception of the world.

It is interesting to note that although our limbic system functions throughout our lifetime, it does not mature. As a result, when our emotional “buttons” are pushed, we retain the ability to react to incoming stimulation as though we were a two year old, even when we are adults.

When incoming stimulation is perceived as familiar, the amygdala is calm and the adjacently positioned hippocampus is capable of learning and memorizing new information. However, as soon as the amygdala is triggered by unfamiliar or perhaps threatening stimulation, it raises the brain’s level of anxiety and focuses the mind’s attention on the immediate situation. Under these circumstances, our attention is shifted away from the hippocampus and focused toward self-preserving behavior about the present moment.

First, when we experience feelings of sadness, joy, anger, frustration, or excitement, these are emotions that are generated by the cells of our limbic system. Second, to feel something in your hands refers to the tactile or kinesthetic experience of feeling through the action of palpation. This type of feeling occurs via the sensory system of touch and involves the postcentral gyrus of the cerebral cortex. Finally, when someone contrasts what he or she feels intuitively about something (often expressed as a “gut feeling”) to what they think about it, this insightful awareness is a higher cognition that is grounded in the right hemisphere of the cerebral cortex.

the air we breathe, even the materials we use to build with, are composed of spinning and vibrating atomic particles, you and I are literally swimming in a turbulent sea of electromagnetic fields. We are part of it. We are enveloped within it, and through our sensory apparatus we experience what is.
