The Hungry Brain: Why Thinking Is So Expensive, and What Happens When Food Runs Low
Published:
Your brain weighs about as much as a small melon, yet it eats like a teenager. Even when you are sitting still and thinking about nothing in particular, it burns through energy at a rate that no other organ of its size comes close to. This single fact, that the brain is metabolically expensive, turns out to be one of the most important constraints in all of neuroscience. It shapes how neurons are built, how they signal, how we learn, and, as recent work suggests, how the brain rations its own performance when food becomes scarce.
Why do two people of the same age have such different brains?
Published:
As people live longer, more and more individuals reach old age without ever developing dementia. That is good news. But it has opened a quieter, more interesting puzzle: even among adults who never cross the threshold into disease, aging does not look the same for everyone. Two people who share a birth year can have brains and cognitive profiles that look strikingly different, and those differences tend to widen as we follow people over time rather than narrow.
