Elderly Clumsiness Brain Changes
2013-06-06 08:01:08

redOrbit Staff & Wire Reports - Your Universe Online Often attributed to age-related decay in vision and physical prowess, incidents of clumsiness in seniors could actually be caused by changes in the brain, researchers from Washington University in St. Louis claim in a new study. Incidents in which older men and women have difficulty reaching for and/or grasping things, such as inability to dial a phone of knocking over a glass while attempting to grab a different object, could be...

Scientists have proven that people use a different part of the brain to learn about social hierarchies than the part normally used for processing other types of information. Ultimate Memory developers incorporated this information into some of the memory-building exercises in the Ultimate Memory 2013 release. New York City, NY (PRWEB) June 04, 2013 One of the most basic of human instincts is survival, and successful survival includes learning who makes up social groups and how best to form...

Scientists Find How Meditation Helps Reduce Anxiety
2013-06-04 12:36:29

Lee Rannals for redOrbit.com — Your Universe Online Scientists at Wake Forest Baptist Medical Center have identified the brain functions involved in how meditation reduces anxiety. The team wrote in the journal Social Cognitive and Affective Neuroscience about how they studied 15 healthy volunteers with normal levels of everyday anxiety. They said these individuals had no previous meditation experience or anxiety disorders. The participants took four 20-minute classes to learn...

Theta Brainwaves Reflect Ability To Overcome Built-in bias
2013-05-08 08:55:51

Brown University Vertebrates are predisposed to act to gain rewards, and to lay low to avoid punishment. Try to teach chickens to back away from food in order to obtain it, and you'll fail, as researchers did in 1986. But (some) humans are better thinkers than chickens. In the May 8 edition of the Journal of Neuroscience, researchers show that the level of theta brainwave activity in the prefrontal cortex predicts whether people will be able to overcome these ingrained biases when doing so...

Early Differentiation Of Higher Brain Structures Affected By Competing Pathways
2013-04-26 11:36:30

Georgia Institute of Technology Sand-dwelling and rock-dwelling cichlids living in East Africa's Lake Malawi share a nearly identical genome, but have very different personalities. The territorial rock-dwellers live in communities where social interactions are important, while the sand-dwellers are itinerant and less aggressive. Those behavioral differences likely arise from a complex region of the brain known as the telencephalon, which governs communication, emotion, movement and...

Prisoners who are psychopaths lack the basic neurophysiological "hardwiring" that enables them to care for others, according to a new study by neuroscientists at the University of Chicago and the University of New Mexico. "A marked lack of empathy is a hallmark characteristic of individuals with psychopathy," said the lead author of the study, Jean Decety, the Irving B. Harris Professor in Psychology and Psychiatry at UChicago. Psychopathy affects approximately 1 percent of the United...

fMRI shows unique brain regions are increasingly devoted to social self-evaluations during puberty A specific region of the brain is in play when children consider their identity and social status as they transition into adolescence -- that often-turbulent time of reaching puberty and entering middle school, says a University of Oregon psychologist. In a study of 27 neurologically typical children who underwent functional magnetic resonance imaging (fMRI) at ages 10 and 13, activity in...

UC Berkeley study shows how we refocus to track down a human, animal or thing A contact lens on the bathroom floor, an escaped hamster in the backyard, a car key in a bed of gravel: How are we able to focus so sharply to find that proverbial needle in a haystack? Scientists at the University of California, Berkeley, have discovered that when we embark on a targeted search, various visual and non-visual regions of the brain mobilize to track down a person, animal or thing. That means...

Studying How Brains Work When Bats Are On The Move
2013-04-19 11:11:44

April Flowers for redOrbit.com - Your Universe Online Two new studies, published this week in Science, examine the mechanisms of animal navigation using bat models. RATS AND BATS The first study is the result of collaboration between University of Maryland (UMD), College Park and Boston University (BU). The findings, based on brain rhythms in bats and rats, challenges a widely-used model — based solely on rodents — of how animals navigate their environment. The study...

Midbrain
2013-07-25 15:13:23

The midbrain, also known as the mesencephalon is the part of the brain most responsible for vision, motor control, arousal, temperature regulation, alertness and hearing. Formation and Orientation The midbrain is found under the cerebral cortex and above the hindbrain. The mesencephalon is not divided into any other portions of the brain unlike the other two vesicles that stem from the neural tube. There are four separate lobes on the side of the cerebral aqueduct within the...

Brain
2013-03-05 13:54:00

Formation and Orientation The development of the brain is broken down into stages. The basic evolution begins in the third week of the embryonic process where the neural plate is formed. By week four, the neural plate has developed into the neural tube. The anterior part of the tube, the telencephalon, grows rapidly as it prepares to later give way to the brain. As time goes on, cells begin to classify themselves as either neurons or glial cells, thus determining their functions. Glial...
