One of the first key terms she memorizes is neurotransmitters because these are the chemicals via which neurons communicate with each other.

Explanation;

-Neurons communicate with each other via electrical events called 'action potentials' and chemical neurotransmitters. At the junction between two neurons (synapse), an action potential causes neuron A to release a chemical neurotransmitter.

-Neurons are connected to each other through synapses, sites where signals are transmitted in the form of chemical messengers.
