298 | Jeff Lichtman on the Wiring Diagram of the Brain

The number of neurons in the human brain is comparable to the number of stars in the Milky Way galaxy. Unlike the stars, however, in the case of neurons the real action is in how they are directly connected to each other: receiving signals over synapses via their dendrites, and when appropriately triggered, sending signals down the axon to other neurons (glossing over some complications). So a major step in understanding the brain is to map its wiring diagram, or connectome: the complete map of those connections. For a human brain that's an intimidatingly complex challenge, but important advances have been made on tinier brains. We talk with Jeff Lichtman, a leader in brain mapping, to gauge the current state of progress and what it implies.

25 | David Chalmers on Consciousness, the Hard Problem, and Living in a Simulation

The "Easy Problems" of consciousness have to do with how the brain takes in information, thinks about it, and turns it into action. The "Hard Problem," on the other hand, is the task of explaining our...

I remember vividly hosting a colloquium speaker, about fifteen years ago, who talked about the LIGO gravitational-wave observatory, which had just started taking data. Comparing where they were to whe...

Brains are important things; they're where thinking happens. Or are they? The theory of "embodied cognition" posits that it's better to think of thinking as something that takes place in the body as a...

There's no question that human activity is causing enormous changes on our planet's environment, from deforestation to mass extinction to climate change. But perhaps there is a tiny cause for optimism...

We humans love to tell ourselves stories about why things happened the way they did; if the stories are sufficiently serious, we label this activity "history." Part of getting history right is simply ...

Economics, like other sciences (social and otherwise), is about what the world does; but it's natural for economists to occasionally wander out into the question of what we should do as we live in the...
