Neuroscience

Every exquisite drawing by Santiago Ramón y Cajal, the founder of modern neuroscience, is marred by a curious mark. Here is the little-known story behind it.

"Organoid" brain tissue models grown in a lab for two years can help scientists study a critical period of development just before and after birth.

To create a good living replica of the human brain, your best hope may be to let “organoid” components assemble it for you.

If gut bacteria can sway their hosts to be selfless, it could answer a riddle that goes back to Darwin.

New math shows how, contrary to conventional scientific wisdom, conscious beings and other macroscopic entities might have greater influence over the future than do the sum of their microscopic components.

Powerful new experiments have uncovered some of the molecular underpinnings of sleep.

Is the brain a blank slate, or is it wired from birth to understand the world?

A new theory explains how fragile quantum states may be able to exist for hours or even days in our warm, wet brain. Experiments should soon test the idea.

Irrationality may be a consequence of the brain’s ravenous energy needs.
