McClatchy: Researchers unravel brain's wiring to understand memory

The human brain contains some 100 billion neurons that are connected by an elaborate network of tiny wires called axons and dendrites. Neurons communicate by passing chemical signals from axons to dendrites at junctions known as synapses. The sender neuron sends a chemical transmitter, called glutamate, across the synaptic gap. The receiver neuron responds by firing a tiny jolt of electricity.
