Final answer:

Signals travel in a neuron through the generation of action potentials, which are electrochemical signals. Neurons communicate with each other through the use of neurotransmitters, which carry signals across synapses.

Step-by-step explanation:

Neurons communicate with each other through the transmission of signals. When a neuron is stimulated by a strong enough signal, an action potential is generated, which is an electrochemical signal that travels along the neuron. This signal is transmitted from one neuron to another through the use of neurotransmitters. Neurotransmitters are chemicals that carry the signal across the synapse, which is the space between the terminal button of one neuron and the dendrite of another neuron. Once the neurotransmitters reach the dendrite of the adjacent neuron, they bind to receptors on the cell surface, initiating a response in the receiving neuron.
