What does it mean to be sentient? What is the self? When the discussion turns to these imponderables, many minds defer rather than get mired in such muddy issues. Neuroscientist Gerald Edelman dives right in. A physician and cell biologist who won a <A href="http://nobelprize.org/nobel_prizes/medicine/laureates/1972/edelman-bio.html">Nobel Prize</A> for his work on the structure of antibodies, Edelman is now obsessed with the enigma of human</blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://discovermagazine.com/2007/brain/cogitator">consciousness—except he doesn’t see it as a mystery. In Edelman’s grand theory of the mind, consciousness is a biological phenomenon. The developing brain undergoes its own process, similar to natural selection: Neurons proliferate and form connections in infancy; experience weeds out the useless from the useful, molding the adult brain in sync with its environment.</blockquote></div><div style="margin: 0px 6px 6px 4px;"><table style="font-size: 11px;border-spacing: 0px;padding: 0px;" cellpadding="0" cellspacing="0" width="100%"><tr><td style="background:transparent;border-width:0px;padding:0px;">&nbsp;</td><td align="right" style="background:transparent;border-width:0px;padding:0px;width:107px" width="107"><a href="http://clipmarks.com/share/7C52C3B3-94BD-4EC9-AD3D-098AA284D80F/blog/" title="blog or email this clip"><img src="http://content7.clipmarks.com/images/c2b-foot.png" border="0" alt="blog it" width="107" height="17" style="border-width:0px;padding:0px;margin:0px;" /></a></td></tr></table></div></div>
