[link\|http://www.wtnh.com/Global/story.asp?S=4189904&nav=3YeX\|WTNH]: Research presented at the Radiological Society of North America\ufffds Annual Meeting shows that heavy use of marijuana may be putting adolescents at risk for delayed development of an important area of the brain--in the language area. It\ufffds here--in the region of the arcuate fasiculus--fasiculus referring simply a bundle of nerve fibers which is now seen to be affected significantly by pot smoking. The paper is [link\|http://rsna2005.rsna.org/rsna2005/v2005/conference/event_display.cfm?em_id=4419258\|here]. It doesn't sound like what you were looking for though.... Hmmm. Google on "cannibis nerve growth" yields [link\|http://www.newscientist.com/article.ns?id=dn8155\|this] article from the New Scientist: A synthetic chemical similar to the active ingredient in marijuana makes new cells grow in rat brains. What is more, in rats this cell growth appears to be linked with reducing anxiety and depression. The results suggest that marijuana, or its derivatives, could actually be good for the brain. In mammals, new nerve cells are constantly being produced in a part of the brain called the hippocampus, which is associated with learning, memory, anxiety and depression. Other recreational drugs, such as alcohol, nicotine and cocaine, have been shown to suppress this new growth. Xia Zhang of the University of Saskatchewan in Saskatoon, Canada, and colleagues decided to see what effects a synthetic cannabinoid called HU210 had on rats' brains. Jiang's paper is [link\|http://www.jci.org/cgi/content/full/115/11/3104\|here]. HTH. Cheers, Scott.
Post #240,005 by broomberg 1/1/06 2:14:33 PM Reply	Very close Not the article I'm looking for, but is probably the basis for it. Here's the article you point to: [link\|http://www.jci.org/cgi/content/full/115/11/3104\|http://www.jci.org/c.../full/115/11/3104] The summary is: In summary, since adult hippocampal neurogenesis is suppressed following chronic administration of opiates (20), alcohol (21), nicotine (22), and cocaine (23), the present study suggests that cannabinoids are the only illicit drug that can promote adult hippocampal neurogenesis following chronic administration. Increased hippocampal neurogenesis appears to underlie the mechanism of anxiolytic- and antidepressant-like effects produced by a high dose of chronic HU210 treatment. The opposing effects of high doses of acute and chronic cannabinoids, together with the anxiolytic-like effects caused by a low dose of cannabinoids, may finally explain discrepancies in the clinical study literature regarding the effects of cannabinoid on anxiety and depression. The key phrase (from the point of memory nerve growth) is: adult hippocampal neurogenesis This googled leads to this: [link\|http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=15718053&dopt=Citation\|http://www.ncbi.nlm....053&dopt=Citation] Which starts off with this: Forebrain acetylcholine regulates adult hippocampal neurogenesis and learning.

Post #240,011 by broomberg 1/1/06 2:26:19 PM Reply	Pretty much Except the weed part is short-term loss (unable to remember recent stuff, unable to form long term memories of things that happen while under the influence), long term-gain (nerve cell growth). Or so it seems in isolated studies. One of the problems with something that removes anxiety and makes you happy is is also removes any reason to do better and excel at something financially rewarding. So chronic use, while rewarding in terms of brain growth, might put you in a position of not being able to afford your weed.
