...just what Tsien & Co. did, focusing not just on the NMDA receptor but on a particular component of it. Called NR2B, it's very active in young animals (which happen to be good at learning), less active in adults (who aren't), and is found mostly in the forebrain and hippocampus (where explicit, long-term memories are formed). The researchers spliced the gene that creates NR2B into the DNA of ordinary mouse embryos to create the strain they called Doogie. Then they ran the mice through a series of standardized tests--sort of a rodent sat. In one, the mice...
...headless human bodies [ESSAY, Jan. 19]. This, he alleges in mock excitement, would be "cloning's crowning achievement." I was the main scientist that Krauthammer cast in the role of Dr. Frankenstein. As he reported, I opined that it would be "possible" to produce human bodies without a forebrain and that it would be "legal" to keep such individuals alive. What Krauthammer failed to report was what I also said in a phone conversation with him: the purposeful creation of human bodies without heads would be viewed as repugnant by society, which would not allow it. I believe that while...
...should you be panicked? Because humans are next. "It would almost certainly be possible to produce human bodies without a forebrain," Princeton biologist Lee Silver told the London Sunday Times. "These human bodies without any semblance of consciousness would not be considered persons, and thus it would be perfectly legal to keep them 'alive' as a future source of organs...
Scientists have not yet identified what factor in smoke lowers levels of MAO B, but Fowler speculates that it may be working synergistically with nicotine to boost dopamine levels. Earlier research showed that nicotine also increases dopamine levels by gripping like Velcro to receptors clustered in the forebrain...
...cultural defoliation--an attempt to destroy "liberal" habitat. If there was any doubt about its momentum, the young velociraptors in Congress--freshman ideologues, mostly, squeaking with Newtish zeal--buried it three weeks ago. These boys and girls aren't even cultural Neanderthals. They're Jurassic. On culture, the limbic forebrain can hold one sound bite at a time, courtesy of Rush Limbaugh or George Will. PBS? "Elitist welfare for the rich." The NEA? "State-subsidized porn." The NEH? "P.c. revisionist history." By a vote of 230 to 194, driven by a rump of dozens of junior members, the House voted...
