When the activity was poorly synchronized, axon branches were instead eliminated. "That tells us that when these cells fire together, associations are strengthened," said Liang Liang, co-senior ...

Although often compared to tree branches, axons are shapeshifters. A brief burst of electrical signaling, for example, causes synaptic varicosities to temporarily expand by 20 percent. The axons also ...

This process, which is known as axon pruning, generates cellular debris that is potentially neurotoxic. Using a functional marker that labels lysosomal activity, Lichtman and colleagues have ...

A long fibre (axon) which is insulated by a fatty (myelin) sheath. They are long so they can carry messages up and down the body. Tiny branches (dendrons) which branch further as dendrites at each ...
