1. Been There, Done That
Would teenage pregnancy rates improve if students simply heard about the reality of young motherhood from those who know?

2. Been There, Seen That
To the Editor:
When a nerve cell dies, it emits a barrage of electrical impulses that greatly exceeds the signal traffic in its neighborhood for a few seconds. Then, the cell’s batteries exhausted, it trails away into silence (“Deja Vu”).
Deja vu, I believe, occurs when this happens in the hippocampus, the part of the brain that encodes memories. For a few seconds, the dying cell screams “Been here before!”
Similar phenomena probably occur when neurons die in other parts of the brain. These supernova-like death throes may be the only occasions when the activity of a single neuron affects our conscious experience.
