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 ...

Chemical synapses are the key connective elements in neuronal networks. They are not only crucial for information processing, but their plasticity also endows the brain with its outstanding capacity ...

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, ...

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 ...

The human brain contains more synapses than there are galaxies in the observable universe (to put a number on it, there are perhaps 100 trillion synapses versus 100 billion galaxies), and now ...

The vast network of neurons, dendrites, axons and other hardware that is responsible for sending messages all over the body is incredibly complex. Nothing can work without this supercomputer ...

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 ...
