Answer: "Long-term potentiation, or LTP, is a process where communication across the synapse __between neurons strengthens___ the connection, which makes further communication __easier___."
Explanation: Long term potentiation is described as process whereby communication across the synapse between neurons strengthens the connection, making further communication easier. This is based on recent patterns of synaptic activity that produces long-lasting increase in signal transmission between two neurons. The LTP in the hippocampus is regulated by the activity of the neurotransmitter: glutamate at NMDA receptors, a necessary component for memory formation.
