I read in the August, 1996 issue of Wired magazine about a Dr. Peter
Fromherz, at the Max Planck Institue in Germany who had successfully
connected leech neurons using a transistor (or was it resistor?). This
seems to be the most advanced stuff out there concerning your question
(if I am wrong about this, please post it up on this newsgroup - I love
this topic). This is being done in vitro though - the article speculates
that proteins will interfere with the transistor, so in vivo has not
been suceeded yet. I checked out his web page (find him by putting his
name in quotes on Webcrawler, and look for Max Planck listings). The
articles I have so far stumbled upon (either through his web site or
Medline) are quite interesting, and I am fascinated by the eventual
implications of this work (spinal cord reconstruction, etc.). Hope this
