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

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...

Do people get caught in the cycle of overeating and drug addiction because their brain reward centers are over-active causing them to experience greater cravings for food or drugs? In a unique prospective study Oregon Research Institute (ORI) senior scientist Eric Stice, Ph.D., and colleagues tested this theory, called the reward surfeit model. The results indicated that elevated responsivity of reward regions in the brain increased the risk for future substance use, which has never been...

Researchers look at ties between early social experiences and adolescent brain function Brains develop in the context of experience. Social experiences may be particularly relevant for developing neural circuits related to the experience of feeling or emotion. Factors such as negative life events and the quality of relationships may be especially influential. Adolescence is a key time to investigate how early social experiences contribute to brain development because it's a period of...

Scientists Probe Source Of A Pulsing Signal In The Sleeping Brain

Technische Universitaet Muenchen New findings clarify where and how the brain's "slow waves" originate. These rhythmic signal pulses, which sweep through the brain during deep sleep at the rate of about one cycle per second, are assumed to play a role in processes such as consolidation of memory. For the first time, researchers have shown conclusively that slow waves start in the cerebral cortex, the part of the brain responsible for cognitive functions. They also found that such a wave...

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...

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...

baudekin
  • A rich embroidered or brocaded silk fabric woven originally with a warp of gold thread.
'Baudekin' seems to be an alternative form of 'baldachin,' from the Italian 'Baldacco,' Baghdad, the city where the material was made.
