X-Message-Number: 24283 From: "Bryan Hall" <> Subject: Brain microtubule recycling Date: Mon, 21 Jun 2004 16:11:31 -0700 I found this article: "How do you presist when your molecules don't?" http://www.sci-con.org/articles/20040601.html in the "Science & Consciousness Review". It claims the whole brain must get recycled about every other month. And contrary to traditional theory, information in the brain is dynamically distributed in patterns rather than located in synapses, recent neuroscience research such as fluorescent tagging has found. In some cases, this turnover is even faster: the half-life of a microtubule is just ten minutes and the actin filaments in dendrites can need replacing within 40 seconds. The author has written many other articles on the brain and consciousness: http://www.btinternet.com/~neuronaut/webtwo_articles.html -Bryan Hall Content-Type: text/html; [ AUTOMATICALLY SKIPPING HTML ENCODING! ] Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=24283
