Q: Why does working memory hold 7 +- 2 items?

Q: Why is possibly transient phase-locking observed between the hippocampus and the entorhinal cortex, the cingulate cortex, and the prefrontal cortex?

Q: Why do the phases of place cells in the hippocampus (relative to the theta rhythm) precess as a rat moves further into the cell’s place field?
