In VitroAxons and dendrites

Image of neurons cultured in a Petri dish. The dendrites, which carry information from other neurons to the cell body, are shown in green. The axons, which carry information from the cell body to other neurons, are shown in blue. Some synapses, i.e. the contact points between axons and dendrites, are labeled in red.
