POPSMinding Mistakes: How the Brain Monitors Errors and Learns from Goofs Where in the brain does the ERN originate? Using functional magnetic resonance imaging, among other imaging methods, researchers have repeatedly found that error recognition takes place in the medial frontal cortex, a region on the surface of the brain in the middle of the frontal lobe, including the anterior cingulate. Such studies implicate this brain region as a monitor of negative feedback, action errors and decision uncertainty—and thus as an overall supervisor of human performance.

The pattern is captured directly on to 35mm film by removing the camera lens and putting the transparent object in its place. The processed film is digitally scanned for uploading. Please note these are not computer generated images but a true analogue of the way light is refracted by the objects I create" Reciprocity's amazing photostream.

POPSFeeling Low Up High: the Lonely Astronaut James Carter, a psychologist at Harvard Medical School, is working on an interactive computer program called Virtual Space Station. With help from 13 American astronauts who have flown on long-duration flights, Carter's team is designing the program so that if an astronaut is suffering from depression or anxiety, or having a conflict with a crewmate, he or she can use the computer for therapy.

Parts of the limbic cortex, which is involved in emotional responses, are smaller in men than in women. Additionally, scientists at McMaster University have found that guys have a smaller density of neurons in areas of the temporal lobe that deal with language processing. Appreciate his naturally upbeat nature Does he seem to be "up" most of the time? It's not your imagination: Male brains produce 52 percent more serotonin (the chemical that influences mood) than female brains, according to a study done at McGill University. And studies show that fewer men than women suffer from depression. Remember his brain is his largest sex organ The preoptic area of the hypothalamus is greater in volume, in cross-sectional area and in the number of cells.

When asked about marriage, he replied: “I do not think you can name many great inventions that have been made by married men.”

POPSEngineer becomes successful artist after stroke rewires his brain Desperately looking for something to relieve his boredom but with little strength to perform everyday tasks, he picked up a pencil and started doodling on paper. 'I just started pencilling these abstract patterns,' he said. 'I wasn't actually drawing anything, just letting my hands do whatever my brain was telling them. 'I couldn't hold the brush properly yet I just had these urges to draw. It was bizarre because before the stroke I'd never been the arty type. I hated it in school.' Doctors convinced the abstract musings were the result of a rewiring of the brain encouraged Ken to develop his new found hobby. 'My doctor told me following a stroke your brain usually rewires itself to avoid the damaged bits and often leads to discovering hidden talents,' he said. Bachelor Ken started transferring his work to computers and within months had become an expert in digital imagery and had even created his own software.
