...HAR1, turns out to be part of a gene that is active in fetal brain tissue only between the seventh and 19th weeks of gestation. Although the gene's precise function is unknown, that happens to be the period when a protein called reelin helps the human cerebral cortex develop its characteristic six-layer structure. What makes the team's research especially intriguing is that all but two of the HARs lie in those enigmatic functional noncoding regions of the genome, supporting the idea that much of the difference between species happens there...
...that she can use to vivify her message. In the film she takes particular pride in some molds that can turn Jello into a model of the human brain. She uses these, she says, to demonstrate how dark thoughts and bad words can worm their way into the human cortex. Before the summer session begins, she blesses her camp's fairly sophisticated audio-visual system to make certain the devil doesn't get into it and make it go blooey at some inopportune moment. One of the high points of the week's merriment is the introduction of a life...
...Foltz is also part of the Allen Brain Atlas' next project, which involves mapping the human cortex. The cortex is where sensory information from the eyes, ears, nose and touch neurons is processed. He and his group are providing samples of human brain tissue, including archived material from patients who have suffered from diseases such as epilepsy, to give researchers a better understanding of which genes are involved in disease states...
...matter how cool your body is during questioning, your mind could still rat you out. Brains require blood to operate, and the harder they work, the more they need. Many regions of the cortex are thought to be recruited for a lie, but three stand out: the anterior (front) cingulate, which reconciles goals and intentions; the right orbital/ interior frontal, which processes the sense of reward; and the right middle frontal, which helps govern tasks requiring more than ordinary thought. Functional magnetic resonance imaging (fMRI) looks for such busy, well-oxygenated areas. Get a hit in all three zones...
...Autistic people have been shown to use their brains in unusual ways: they memorize alphabet characters in a part of the brain that ordinarily processes shapes. They tend to use the visual centers in the back of the brain for tasks usually handled by the prefrontal cortex. They often look at the mouth instead of the eyes of someone who is speaking. Their focus, says psychologist Ami Klin of Yale's Child Study Center, is "not on the social allegiances - for example, the longing gaze of a mother - but physical allegiances - a mouth that moves...
