Neurons are information messengers. They use electrical impulses and chemical signals to transmit information between different areas of the brain, and between the brain and the rest of the nervous system. … Neurons have three basic parts: a cell body and two extensions called an axon (5) and a dendrite (3).

How do neurons work?

When a neuron spikes it releases a neurotransmitter, a chemical that travels a tiny distance across a synapse before reaching other neurons (Fig 1). Any time a neuron spikes, neurotransmitters are released from hundreds of its synapses, resulting in communication with hundreds of other neurons.

What is a neuron for dummies?

Neurons are cells that form the core of nervous systems because they have the ability to receive and transmit signals. Neurons have a unique elongated shape and consist of three main parts: Nerve cell body: The rounded part of the neuron. … The dendrites act like tiny antennae that pick up signals from other cells.
