Transmission of information along the axon takes place via an electrochemical process called the

Neurotransmission  

Explanation:

The transfer of the information from one neuron to another takes place through the release of the chemical substances from the axon of one neuron to the dendrite of another via synaptic junction.

The chemicals that is transferred between two neurons is known as neurotransmitter and the process is known as neurotransmission.

The brain consists of multiple neurons and this is how the information is transferred across the brain and body.
