THE BRAIN IS NOT FOR THINKING
- The brain’s most important job is not emotion, rationality or imagination; it is to keep you alive and well by controlling and managing your energy budget.
- Called allostasis, body budgeting requires the brain to predict the amount of energy needed based on past actions.
- To paraphrase neuroscientist Dr. Lisa Feldman Barret “Everything your brain creates, from memories to hallucinations, from ecstasy to shame, is part of this [body budgeting] mission.”
“LEFT” BRAIN VS “RIGHT” BRAIN IS A METAPHOR
- The notion that the left brain is rational while the right brain is creative is actually based on a metaphor,; it was never to be taken literally.
- The reason being that the brain functions as a single unit, not as distinctive parts with their own unique functions. Indeed, the brain is a network of neurons that communicate with one another from various parts of the brain.
- Think about it, if brain functions were strictly localized, then someone with a stroke for example in the left side of the brain would never be able to speak again!
THERE IS NO SUCH THING AS A LIMBIC SYSTEM DEDICATED TO EMOTION PROCESSING
- What is erroneously called “limbic system” actually refers to limbic circuitry, which is associated with many vital functions including the autonomic system, immune system, and endocrine system.
- Emotion processing is only one of many other contributions of those neurons, as they connect to various brain structures from the amygdala to the cerebral cortex.
