Most folks probably couldn't locate their parietal lobe with a map and a compass. For the record, it's at the top of your head - aft of the frontal lobe, fore of the occipital lobe, north of the temporal lobe. What makes the parietal lobe special is not where it lives but what it does - particularly concerning matters of faith...
...preference. Infrared imaging is typically used to detect heat, which is just what the researchers were looking for. The volunteers were shown pictures of different pairs of drinks from their original list and asked to mentally decide which one they liked better while Chau and Luu monitored their frontal-lobe activity...
...trained to use them and must rehearse a random, energy-intensive brain task like mentally singing a song in order to light up a pattern of brain activity that sends a signal to the researchers. The new technique extracts information much more directly by targeting the frontal lobe's preference functions. What's more, while other studies have required the subjects to activate their brains over and over again so that researchers could average the subtle changes in their scans across many trials, Chau and Luu's technique is precise enough that they needed to look only once. "This...
...seems that great artists are always known by certain iconic stories. Who can forget the tragedy of Vincent van Gogh cutting off his left ear lobe after a confrontation with his friend Paul Gauguin? And then there’s Paul Gauguin himself, who is known for his attempt to escape European civilization in search a pre-civilization good life in Tahiti. There is the sadly romantic story of the dwarfen Henri Toulouse-Lautrec, who would frequent the Moulin Rouge to pine after the beautiful, tall dancer Jane Avril.But Daniel Kehlmann, the author of the novel...
...Persuading a teenager to go to bed and get up on a reasonable schedule is another matter entirely. This kind of decision making has less to do with the frontal lobe than with the pineal gland at the base of the brain. As nighttime approaches and daylight recedes, the pineal gland produces melatonin, a chemical that signals the body to begin shutting down for sleep. Studies by Mary Carskadon at Brown University have shown that it takes longer for melatonin levels to rise in teenagers than in younger kids or in adults, regardless of exposure to light or stimulating activities...
