Electrical brain stimulation for soldiers: a shot in the dark

Ever since the invention of the two-handed club, warfare and technology have been inextricably linked. More often than not, the humans who are sent into battle have been mere pawns in these hi-tech contests. So we shouldn’t be surprised if the military are eying up one of the most exciting new technologies in neuroscience, noninvasive brain stimulation (NIBS), which uses electrical or magnetic fields to remotely influence the activity of particular parts of the brain and could boost physical and mental performance.

Uncanny synchronicity in the brain during near death experiences and meditation

The Buddha is said to have entered a state of deep meditation as he died

People who have had a near-death experience commonly report a sense of wellbeing and peace, detachment from the world, the feeling of being outside their own body, and seeing a bright light. People who meditate deeply often report very similar sensations. Research reported yesterday in the journal PNAS suggests what may link the two experiences.

Cigarettes and cupcakes: mindfulness meditation reduces craving

Delicious cupcakes
Resistance is useless: it just makes the craving worse

Life is so unfair. Trying to give up something you’re addicted to just makes you crave that thing even more, whether it’s cigarettes, alcohol or sugar. You’re caught in a Catch-22: you want to quit, but the more you try, the harder it gets to resist temptation. Perhaps the key is not to try so damn hard, but instead improve your brain’s capacity for self-control.

It might just work… Continue reading “Cigarettes and cupcakes: mindfulness meditation reduces craving”

The Universe in a Single Atom by His Holiness the Dalai Lama – review

The Dalai Lama wants every cognitive scientist to learn how to meditate. He believes this will give them insights into the mind and consciousness that plastering electrodes on scalps or scanning brains with powerful magnetic fields never could.

Whereas a scientist looks at the mind from the outside, he says, an experienced meditator examines it from within. Neither sees the whole picture and so we could learn a great deal by combining the two perspectives. Continue reading “The Universe in a Single Atom by His Holiness the Dalai Lama – review”

Introducing Plastic Brain

His Holiness the Dalai Lama keeps a plastic brain with detachable labelled components on the desk in his office in Dharamsala, India. It was a gift from his friend the late Robert Livingstone, a neuroscientist at the University of California, San Diego, whom he credits with opening his eyes to the findings of modern biology. Livingstone founded the world’s first department of neuroscience at UCSD in 1965 and dedicated his career to linking the anatomy of the brain to the workings of the mind.

That, in a nutshell, is why I’ve called my new blog Plastic Brain. For me, the model brain sitting on the Dalai Lama’s desk symbolises the way ancient contemplative practices and science have come together over the past three decades as the gulf between the intangible mind and the inscrutable brain has narrowed. These are exciting times for neuroscience and psychology. Continue reading “Introducing Plastic Brain”
