Describe the process by which neurons communicate with one another electrochemically. Include a detailed description of how neurons receive information across the synapse, generate PSPs, and conduct action potentials.

Neurons communicate with one another at junctions called synapses. At a synapse, one neuron sends a message to a target neuron—another cell. Most synapses are chemical; these synapses communicate using chemical messengers. Other synapses are electrical; in these synapses, ions flow directly between cells.
