Now here’s<\/span> a fascinating study: turns out that victims of blindsight<\/a> can see better than so-called “healthy” individuals. At least, one fellow with a patchy version of the condition was able to detect subtler visual cues in his blind field than in his sighted one. (Here’s the original paper<\/a>: here’s a summary<\/a>.) This suggests that certain “primitive” traits in our neurological evolution didn’t so much disappear as get ground beneath the boots of more recent circuitry, and that \u2014 once released from those Johnny-come-lately overlays \u2014 they come off the leash. And primitive or not, they’re better<\/span> than what came after.<\/p>\n

Or in other words, once again, the reptile brain could really shine if the pointy-haired homunculus would just get the hell out of the way.<\/p>\n

I wrote a story<\/a> back in the nineties with a similar punchline \u2014 that the hindbrain was still alive<\/span> in its own right, still potentially autonomous, and that only after the neocortex had died was it able to wake up, look around, and scream in those last brief moments before it too expired. But now I’m thinking I didn’t go far enough \u2014 because after all, who’s to say the reptile brain has to die when the upper brain does? I mean sure, we’ve got the Terry Schiavos and the other fleshy rutabagas of the world, clusters of organs and bed sores on life support. But we’ve also got the schizophrenics, who hear voices and won’t meet our eyes and whose frontal lobes are smaller<\/a> than most would consider normal. And most frighteningly of all, we’ve got these other<\/span> folks<\/a>, people with heads full of fluid, mid- and hindbrains intact, cerebra reduced to paper-thin layers of neurons lining the insides of empty skulls \u2014 wandering through life as engineers and schoolteachers, utterly unaware of anything at all out of the ordinary until that fateful day when some unrelated complaint sends them into an MRI machine and their white-faced doctors say, Er, well, the good news is it can’t be a brain tumor because…<\/span> <\/p>\n

There’s a range, in other words. You don’t need anywhere near a complete brain to function in modern society (in fact, there are many obvious cases in which having a complete brain seems to be an actual disadvantage). And in a basic survival sense, the ability to write and appreciate the music of Jethro Tull and do other “civilised” things aren’t really that important anyway.<\/p>\n

So now I’m thinking, tewwowist virus: something engineered to take out higher brain functions while leaving the primitive stuff intact. Something that eats away at your cognitive faculties and lets your inner reptile off the leash, something that strips your topheavy mind down to its essentials, something that speeds your reflexes and cranks your vision even as it takes the light from your eyes.<\/p>\n

I’m thinking zombies. Not the shuffling Romero undead or the sentient philosopher’s metaphor, not even the drug-addled brain-damaged pseudoresurrectees of the real-world Caribbean. I’m thinking something faster and more rigorous and more heartbreaking, far more dangerous and far tougher to kill, and I’m thinking hey, if I can do it for vampires…<\/span><\/p>\n

I’m also thinking of writing another book.<\/p>\n","protected":false},"excerpt":{"rendered":"
