1 | 2 | 3 | NextElectrical Stimulation Through The Spinal Cord May Ease Parkinson?s Symptoms 1 Citation Neural activity in the brain of a Parkinsonian rat before (top) and after (bottom) electrical stimulation is applied to its spinal cord. Delivering electrical stimulation to the spinal cord through tiny, platinum electrodes could ease the severe motor deficits of Parkinson?s disease as effectively as a much more intrusive procedure currently in clinical use, according to a new study in rodents. If the findings are confirmed in humans, scientists say, the procedure could dramatically improve, technorati.com

1 Citation It happens; sometimes they die . "Death by hyperthermia" is the official designation. When it happens to young children, the facts are often the same: An otherwise loving and attentive parent one day gets busy, or distracted, or upset, or confused by a change in his or her daily routine, and just... forgets a child is in the car. It happens that way somewhere in the United States 15 to 25 times a year, parceled out through the spring, summer and early fall. It's a fascinating piece of rep, technorati.com

Unexpected Outcomes Facilitate Learning 1 Citation The human brain?s sensitivity to unexpected outcomes plays a fundamental role in the ability to adapt and learn new behaviors, according to University of Pennsylvania researchers. Using a computer-based card game and microelectrodes to observe neuronal activity of the brain, the Penn study, published this week in the journal Science , suggests that neurons in the human substantia nigra, or SN, play a central role in reward-based learning, modulating learning based on the discrepancy between, technorati.com

The jury-rigged, symphonic human brain 1 Citation Last month there was an unbearably sad story in the Washington Post magazine, about parents who forgot their kids in cars with fatal consequences. Read it here. article excerpt: The human brain, he says, is a magnificent but jury-rigged device in which newer and more sophisticated structures sit atop a junk heap of prototype brains still used by lower species. At the top of the device are the smartest and most nimble parts: the prefrontal cortex, which thinks and analyzes, and, technorati.com

Writer?s Cramp Traced to Pathways Connecting Brain Areas 1 Citation By Sridhar Nadamuni Writing professionals may run into muscle disorders such as writer?s cramp. Previous studies suggested that changes in the gray matter of several brain areas basal ganglia (structures that help control and start movement), sensorimotor cortex (controls sensory and motor functions), thalamus (coordinates multiple impulses including some related to the senses) and cerebellum (controls voluntary movements, posture and balance) may be responsible for the disorders.

Effects of neurological damage on production of formulaic language 1 Citation Early studies reported preserved formulaic language in left hemisphere damaged subjects and reduced incidence of formulaic expressions in the conversational speech of stroke patients with right hemispheric damage. Clinical observations suggest a possible role also of subcortical nuclei. This study examined formulaic language in the spontaneous speech of stroke patients with left, right, or subcortical damage. Four subjects were interviewed and their speech samples compared to normal speakers. Ra, technorati.com

Comment: Basal Ganglia Volume & Shape in Children with ADHD 1 Citation Volumetric abnormalities of basal ganglia have been associated with attention deficit hyperactivity disorder (ADHD) especially in boys. ADHD is a prevalent neuropsychiatric syndrome characterized by excessive difficulty with focusing attention, sitting still and controlling impulses. Before the era of neuroimaging, neurologists reported motor impairments and cognitive anomalies that implicated the frontal lobe. Among these subcortical regions, the basal ganglia have been particularly emphasize, technorati.com

The Unexpected Is A Key To Human Learning 1 Citation It seems we learn better when dealing with unexpected outcomes. More importantly, they have a better sense of which parts of the brain are active in this form of learning. Basic finding: " a lucky win seems to be retained better than a probable loss ." Penn Neuroscientists Find That The Unexpected Is A Key To Human Learning The human brain's sensitivity to unexpected outcomes plays a fundamental role in the ability to adapt and learn new behaviors, according to a new study by a team of psych, technorati.com

Unexpected outcomes key to human learning 1 Citation Washington, March 14 (ANI): Psychologists and neuroscientists at the University of Pennsylvania say that unexpected outcomes play a significant role in human learning. Describing their study in the journal Science, the researchers revealed that they used a computer-based card game and microelectrodes to observe neuronal activity of the brain. They said that their study suggested that , technorati.com

Question to Refuel Finances Past Media Fears 1 Citation If you listened lately to the media?s constant streams of financial fears, you likely failed to shop much for loved ones over Christmas. Not that buying less detracts from the magic of Christmas. Yet, sadly, the gloomy news turned into poor proceeds for stores, just as fear blocked winning opportunities from your own brain. Why so?
