A researcher identifies a neuron in the brain that sends signals to a second neuron. After stimulating the neurons, the researcher finds that the signal being sent between the neurons is stronger than before. Which phenomena can explain this result?
A) consolidation
B) cross-cortical storage
C) long-term potentiation
D) interference
Answer: C
Rationale: Long-term potentiation (LTP) means that there is an enduring increase in connectivity and transmission of neural signals between nerve cells that fire together. LTP was first discovered to occur when researchers stimulated specific pathways in part of a rabbit's brain and recorded activity in the hippocampus.
