...When olfactory cells regenerate, they grow long neural shoots called axons, which connect to the brain. The axons are like phone wires that carry the signals that allow the brain to differentiate between various smells. They transport these signals with the help of olfactory ensheathing glia (OEG) cells. Because axons extend from all nerve cells, scientists have long wondered what would happen if OEG cells were taken from the olfactory bulb and introduced somewhere else?say, in the spinal cord of someone like Nan Davis...
...overemphasized the importance of neural activity and brain physiology and made no mention of the need for moral guidance. Teenagers may read between the lines of the physiological mumbo jumbo and giggle with glee as they decide there is nothing they can do to change their ways. Why not discuss how dysfunctional family situations affect teen behavior? There is more to raising a teenager than studying brain physiology. Cecil Asfour Dallas...
...figured I could do it too." After detouring from artificial limbs to artificial intelligence, Howard is currently developing software that will enable J.P.L.'s forthcoming Mars probes to choose their landing sites and navigate the Martian surface by mimicking the way a human might handle the job. Her "neural network" reacts the same way humans do when facing rugged terrain, avoiding steep grades and accelerating through straightaways...
...People always look for the straightest, clearest path, so that's what we map to the robot," she says. The early result is SmartNav, a rover the size of a lawn mower that is controlled by a neural network capable of distinguishing sand, concrete and gravel. On Mars, such networks could keep rovers exploring rather than waiting for instructions...
