YOUR BRAIN IS NOT FOR THINKING : EVERY THOUGHT you have, every feeling of happiness or anger or awe you experience on The World Students Society.
Every kindness you extend and every insult you bear or sling is part of your brain's calculations as it anticipates and budgets your metabolic needs.
This view of the brain has many implications for understanding human beings. So often, for example, we conceive ourselves in mental terms, separate from the physical. A bad stomach ache that follows an indulgent meal may send us to the gastroenterologist -
But if we experience that same ache during a messy divorce, we may head to a psychotherapist instead. At the gastroenterologist's office, we experience our discomfort as an underlying physical problem; at the therapist's office, we experience the same discomfort as anxiety - a psychological disturbance, physically manifested.
FIVE HUNDRED MILLION YEARS AGO - A TINY SEA CREATURE changed the course of history : it became the first predator. It somehow sensed the presence of another creature nearby, propelled or wiggled the way over, and deliberately ate it.
This new activity of hunting started an evolutionary arms race. Over millions of years, both predators and prey evolved more complex bodies that could sense and move more effectively to catch or elude other creatures.
Eventually, some creatures evolved a command center to run those complex bodies. We call it a brain. The story of how brains evolved, while admittedly just a sketch, draws attention to a key insight about human beings that is too often overlooked.
Your brain's most important job isn't thinking; its running the systems of your body to keep you alive and well. According to recent findings in neuro-science, even when your brain does produce conscious thoughts and feelings, they are more in service to the needs of managing your body than you realize.
And in stressful times like right now, this curious perspective on your mental life may actually help to lessen your anxieties.
Much of the brain's activity happens outside your awareness. In every moment, your brain must figure out your body's needs for the next moment and execute a plan to fill those needs in advance. For example, each morning as you wake, your body anticipates the energy you'll need to drag your sorry body out of bed and start your day.
It proactively floods your bloodstream with the hormone cortisol, which helps make glucose available for quick energy.
YOUR BRAIN runs your body using something like a budget. A financial budget tracks money as it's earned and spent.
The budget for your body tracks resources like water, salt and glucose as you gain and lose them. Each action that spreads resources, such as standing up, running and leaning, is like a withdrawal of your account. Actions that replenish your resources, such as eating and sleeping, are like deposits.
The scientific name for body budgeting is allostasis. It means automatically predicting and preparing to meet the body's needs before they arise.
Consider what happens when you're thirsty and drink a glass of water. The water takes about 20 minutes to reach your bloodstream, but you feel less thirsty within mere seconds. What relieves your thirst so quickly? Your brain does.
It has learned from your past experience that water is a deposit to your body budget that will hydrate you, so you're brain quenches your thirst long before the water has any direct effect on your blood.
This budgetary account of how the brain works may seem plausible when it comes to your bodily functions. It may seem less natural to view your mental life as a service of deposits and withdrawals. But your own experience is rarely a guide to your brain's inner workings.
