Definitions:

Long-Term Potentiation

A lasting enhancement in signal transmission between two neurons that results from stimulating them synchronously, crucial for learning and memory.

Sending Neurons

Neurons that transmit signals from their axon terminals to another neuron's dendrites or cell body in the process of neural communication.

Neurotransmitters

Chemical messengers that cross the synaptic gap between neurons. When released by the sending neuron, neurotransmitters travel across the synapse and bind to receptor sites on the receiving neuron, thereby influencing whether that neuron will generate a neural impulse.

Receiving Neuron

A neuron that receives chemical signals (neurotransmitters) from another neuron during neurotransmission.
