What is the purpose of the blood-brain barrier? Describe its maintenance from a cellular level. - Answer
The blood-brain barrier is a diffusion barrier which prevents most particles from entering the central

Describe how memories are stored and retrieved in the brain. Include a specific brain region. - Answer

retrieval. The involvement of the limbic system explains why emo!onally charged events result in our
most vivid memories.
