This is the happiness of the Buddha

Last weekend, a few months after the publication of Siddhartha’s Brain in Dutch, I gave a lecture about the science of mindfulness to a very polite, attentive audience at the wonderful Brainwash Festival in Amsterdam. Here’s a transcript.

Ladies and gentlemen, each and every one of us here will face two key problems in our lives. The first problem is that as creatures of biology, particularly when we’re young, we spend lots of time and energy pursuing the pleasures of sex, money, social status. And as biological creatures we also invest a lot of energy trying to avoid pain and unpleasantness.

For most people, this is what they mean when they talk about the pursuit of happiness. But pleasures never last and sooner or later, as we get older, we’re all going to experience the pain and unpleasantness of ill health and ageing. It’s just a fact of life.

So that’s our first problem, and I’m sure none of this is news to you.

The second problem is much more surprising and counterintuitive, but is just as important. The second problem is that we think way too much. Every second that we’re awake, our lives are dominated by what’s going through our minds. (more…)

Is this the brain’s mindfulness switch?

Journalists adore research that allows them to write stories along the lines of “scientists have tracked down the brain’s love HQ” or “researchers have located the brain’s god spot”. It is very satisfying to imagine that we can divide the brain into neat components with distinct functions like the parts of a car engine. We dream that one day, neuroscientists will be able to lift the bonnet (or the hood if it’s an American brain), point and say “here’s the valve that causes schizophrenia – we can readjust that with this chemical spanner. Here’s the tank that causes OCD when it overflows – we can drain that by turning this tap here. Over there are the spark plugs that we clean up to cure depression …”

Unfortunately the brain is a lot messier and more wonderful than your average motor engine, which is why we’re still standing over it scratching our heads trying to figure out how on earth it all works. It’s a tangle of connections, with myriad networks of components involved in creating thoughts, consciousness, sensations and emotions.

So it is with a mixture of excitement and wariness that I approach a study by researchers at Beijing Normal University in China that seems to point to a particular part of the brain that switches mindfulness on and off. It’s called the thalamus (shown in red on the animated gif), a pair of bulbous structures that sit at the top of the brainstem (yellow) on the midline of the brain. The thalamus plays a pivotal role as the brain’s switchboard, relaying information from all the senses apart from smell to the cerebral cortex, which is the thinking, conscious part of the brain.
