Brains Must Feel Safe for Education

The brain’s main job is prioritizing information relevant to our survival. Anything that suggests the possibility of danger, whether real or imagined, becomes a higher priority than anything else that is going on at that moment. This data is processed first, shifting our attention from cognitive processes down to the faster-acting limbic system, while more complex cerebral operations shut down. Survival always overrides problem-solving, analyzing, remembering, pattern-detection and other ra...

 We All Talk About One Another Behind Our Backs

I’ve often thought that the single most devastating cyberattack a diabolical and anarchic mind could design would not be on the military or financial sector but simply to simultaneously make every e-mail and text ever sent universally public. It would be like suddenly subtracting the strong nuclear force from the universe; the fabric of society would instantly evaporate, every marriage, friendship and business partnership dissolved. Civilization, which is held together by a fragile web of t...

 Childhood is Naturally Mindful

As children, we are remarkably aware. We absorb and process information at a speed that we’ll never again come close to achieving. New sights, new sounds, new smells, new people, new emotions, new experiences: we are learning about our world and its possibilities. Everything is new, everything is exciting, everything engenders curiosity. And because of theinherent newness of our surroundings, we are exquisitely alert; we are absorbed; we take it all in. And what’s more, we remember: becau...

 How the Adverse Affects of Stress Were Discovered

Lots of research has gone into trying to understand how maternal stress affects brain development. And we have begun to answer this question at the most intimate level possible: the level of cell and molecule. For this progress we mostly can thank the klutzy researcher Hans Selye. He is the founder of the modern concept of stress. As a young scientist, Selye would grind up “endocrine extracts”, which presumably contained active stress hormones, and inject them into rats to see what the ra...
