SummaryThe poster from the 2008 Holiday Lectures on Science, Making Your Mind: Molecules, Motion, and Memory. It illustrates the structure and function of a neuron, including how it transmits electrical and chemical signals.
A neuron is a specialized cell that transmits information by electrical and chemical signals. A typical neuron has dendrites, a cell body, an axon, and axon terminals. Axon terminals transmit signals and dendrites receive signals. This poster illustrates how synapses work to transmit information from neuron to neuron, and how action potentials transmit electrical signals along the neuron.
