Ultrastructural analysis of cortical synaptic connectivity by electron microscopy has typically been limited to small volumes of tens of micrometres in extent 1,2,3,4,5,6,7. Similarly, connectivity ...

The human brain is a network of nearly 100 billion neurons forming as many as a quadrillion synapses. Exactly how this massively distributed information processor produces and represents mental ...

Neurons are complicated, but the basic functional concept is that synapses transmit electrical signals to the dendrites and cell body, and axons carry signals away. In one of many surprise findings, ...

Scientists have discovered a new kind of synapse in the tiny hairs on the surface of neurons. The commonly overlooked protrusions called primary cilia contain special junctions that act as a shortcut ...

New experiments are settling a century-long debate between two camps over how neurons communicate. The surprise: both sides are right I sliced the heart in two with a big kitchen knife. All was ...

“You expect nerve cells to grow to find the one they like,” said Alan Roberts, a neuroscientist at the University of Bristol in the U.K. and lead author of the study. “These experiments suggest they ...

You probably think of your nervous system as a kind of computer network, or some kind of electrical system that passes nerve impulses around. But in reality, the miraculous journey of a signal ...
