Our interconnected neurons help us process different types of information. Synapses are the gaps between neurons. <span>When an impulse reaches the end of one axon, it is now an action potential. This electric signal cannot leap across this gap so as to speak. Special chemicals called neurotransmitters have this role to be possible. The best answer is thus neurotransmitters. </span>
