rydellen,

I think you have said it better than my damaged brain can remember it. Either way you say it, the same thing happens when the damaged cells self-destruct/deactivate.

Some researchers do not mention the tRNA system but do relate a similar self-destruct process.

The brain absorbs the shut down brain cells so quickly that it is difficult to image them. They can observe this behavior en vitro as the cells try to re-establish axonal connections where the damaged brain cells leave gaps.
