1. How Biology Affects Behaviour

3. How Neurons Send Messages

Neurons Communicate Using Electricity and Chemicals

An electrical charge moves through the neuron itself and chemical messengers called neurotransmitters are used to transmit information between neurons.

Within the neuron, when a signal is received by the dendrites, is it transmitted to the soma in the form of an electrical signal, and, if the signal is strong enough, it may then be passed on to the axon and then to the terminal buttons. If the signal reaches the terminal buttons, they are signaled to emit chemicals known as neurotransmitters, which communicate with other neurons across the spaces between the cells, known as synapses.
