I was wondering if dendrites grow in response to the electrical stimulus between neurons. If so, what is the mechanism of action? How exactly does it stimulate growth.

 

Also, what are some things that can cause decay of dendrites and an increased bridging distance between neurons?

I don't know about your background knowledge in this area, but here's a paper that has some really good information;

Thanks, I'll check that out.
