The operational unit of the brain is the neuron. Thinner than a human hair, each of these consists of a cell body, dendrites and an axon. Dendrites branch out, like fronds of seaweed, and receive electrical messages from hundreds of other neurons. These travel to the cell body, which con...

Using tracers, they inject dye in one region of the brain and the motor proteins of the neurons in that region will carry that chemical down their axons to all the regions that the neuron connects with. Another method would be to use brain scans to monitor what brain regions fire when a...
But if enough chemicals touch his hair to raise his charge over a certain point—the neuron’s “threshold potential”—then it triggers an action potential, and our guy is electrocuted. This is a binary situation—either nothing happens to our guy, or he’s fully electrocuted. He can’t...
A von Economo neuron, also known as a spindle neuron, is a unique cell with several interesting characteristics: 1) It has a long axon and on the opposite side of the cell body has only one long dendrite, resembling a spindle and hence the nickname. ...
