...brains of men and women as they tried to escape a 3-D virtual-reality maze and found that the sexes use different parts of the brain to process directions. Men relied on their left hippocampus and used geometry to find their way. Women used their right frontal cortex, trusting memory to keep landmarks in mind...
ATTENTION! Using a special MRI technique, researchers have mapped out regions of the brain involved in paying attention. The frontal cortex and parietal cortex--in the front and back of the brain, respectively--appear to light up when subjects focus on certain signals. Then, as the new stimuli are processed, the visual cortex in the lower rear of the brain moves into action. The finding may help researchers better understand attention-deficit/hyperactivity disorder and even schizophrenia...
...humans to insects. "I don't argue that the great majority of animals should have legal rights," Wise says -- only those entitled to them by reason of mental powers and self-awareness. It seems to be all right to boil lobsters, by the way, since they have no brain cortex or its equivalent. Wise's argument seems to denigrate the divinity of mankind, and perhaps of all creation -- an unnecessary public relations error, I would argue, and perhaps a massive missing of the central point: a holiness and beauty in the world that makes stewardship the only civilized behavior...
...system for remembering. A single memory is made of tiny pieces of information accumulated and stored over time. Those bits are held in a complex network of some 100 billion neurons, or nerve cells, that can make thousands of connections with other cells in the brain. Subsystems within the cortex handle specific things like names, sounds, textures, faces and smells. Say the word dog, and the busy brain fires up a host of images, sensory impressions and emotions, then reconstructs a specific, unique memory...
...thing, but what about having a vicarious sensory and kinesthetic experience of your favorite sport? Within the next 50 years, neural-input units will become as standard a feature of your entertainment console as the remote control. With this hairnet-like apparatus sending complex algorithmic signals into your motor cortex and parietal lobe, you'll actually feel what it's like to be slashed across the eyes by a high-sticking Tie Domi. Seated on your couch, you'll writhe in agony from lactic-acid accumulation at the end of an Ironman Triathlon. And you'll hop around your living...
