In Blur of A.D.H.D., Sleep Troubles May Be a Culprit. Getty Images Diagnoses of attention hyperactivity disorder among children have increased dramatically in recent years, rising 22 percent from 2003 to 2007, according to the Centers for Disease Control and Prevention.
But many experts believe that this may not be the epidemic it appears to be. Many children are given a diagnosis of A.D.H.D., researchers say, when in fact they have another problem: a sleep disorder, like sleep apnea. The confusion may account for a significant number of A.D.H.D. cases in children, and the drugs used to treat them may only be exacerbating the problem. Allen Brain Atlas - Welcome. Mirror Neurons. Mirror Neurons PBS air date: January 25, 2005 ROBERT KRULWICH: Hello again.
Gaze into a mirror, and what do you see? Well, I see my face, of course. But in my face I see moods, I see shifts of feeling. We humans are really good at reading faces and bodies. Ask yourself, "Why do people get so involved, so deeply, deeply involved, with such anguish, such pain, such nail biting tension over football? " COMMENTATOR: The Cleveland Browns are gambling on defense.
ROBERT KRULWICH: Why are we such suckers for sports? Well, as it happens, scientists have an explanation for this strange ability to connect. DANIEL GLASER: It had never been found on a cellular level before. ROBERT KRULWICH: A set of brain cells, found on either side of the head, among all the billions of long branching cells in our brain, these so-called "mirror neurons," have surprising power.
Is Pornography Driving Men Crazy? - Naomi Wolf. Exit from comment view mode.
Click to hide this space NEW YORK – It is hard to ignore how many highly visible men in recent years (indeed, months) have behaved in sexually self-destructive ways. Some powerful men have long been sexually voracious; unlike today, though, they were far more discreet and generally used much better judgment in order to cover their tracks. Of course, the heightened technological ability nowadays to expose private behavior is part of the reason for this change. But that is precisely the point: so many of the men caught up in sex-tinged scandals of late have exposed themselves – sometimes literally – through their own willing embrace of text messages, Twitter, and other indiscreet media. What is driving this weirdly disinhibited decision-making?
There is an increasing body of scientific evidence to support this idea. The hypothesis among the experts was that pornography was progressively desensitizing these men sexually. The New Map Of The Brain. Trying to map the brain has always been cartography for fools.
Most of the other parts of the body reveal their workings with little more than a glance. The heart is self-evidently a pump; the lungs are clearly bellows. But the brain, which does more than any organ, reveals least of all. The 3-lb. lump of wrinkled tissue--with no moving parts, no joints or valves--not only serves as the motherboard for all the body's other systems but also is the seat of your mind, your thoughts, your sense that you exist at all.
You have a liver; you have your limbs. The struggle of the mind to fathom the brain it inhabits is the most circular kind of search--the cognitive equivalent of M.C. Modern scientists have done a far better job of things, dividing the brain into multiple, discrete regions with satisfyingly technical names--hypothalamus, caudate nucleus, neocortex--and mapping particular functions to particular sites. Chapter 9: Limbic System. The limbic system is a convenient way of describing several functionally and anatomically interconnected nuclei and cortical structures that are located in the telencephalon and diencephalon.
These nuclei serve several functions, however most have to do with control of functions necessary for self preservation and species preservation. They regulate autonomic and endocrine function, particularly in response to emotional stimuli. They set the level of arousal and are involved in motivation and reinforcing behaviors.
