Impulses travel from one neuron to the next primarily **by converting from an electrical impulse to a chemical signal to travel across the synapse between neurons**. Here’s how it works:
1. **Electrical Impulse**: When an impulse, called an action potential, travels down the axon of a neuron, it is an electrical signal.
2. **Synapse**: When the action potential reaches the end of the axon, it triggers the release of neurotransmitters, which are chemical messengers, into the synaptic cleft (the gap between two neurons).
3. **Chemical Signal**: The neurotransmitters then bind to receptors on the surface of the neighboring neuron, converting the chemical signal back into an electrical signal in the receiving neuron, which can then generate its own action potential.
This process is fundamental to neuronal communication in the nervous system.
