A Mother's Love Is Good For Child's Brain
2012-01-31 04:52:38

School-age children whose mothers nurtured them early in life have brains with a larger hippocampus, a key structure important to learning, memory and response to stress. The new research, by child psychiatrists and neuroscientists at Washington University School of Medicine in St. Louis, is the first to show that changes in this critical region of children's brain anatomy are linked to a mother's nurturing. Their research is published online in the Proceedings of the National Academy...

In a 2007 episode of the television show Boston Legal, a character claimed to have figured out that a cop was racist because his amygdala activated — displaying fear, when they showed him pictures of black people. This link between the amygdala and fear — especially a fear of others unlike us, has gone too far, not only in pop culture, but also in psychological science, say the authors of a new paper which will be published in the February issue of Current Directions in...

In the classic film "12 Angry Men," Henry Fonda's character sways a jury with his quiet, persistent intelligence. But would he have succeeded if he had allowed himself to fall sway to the social dynamics of that jury? Research led by scientists at the Virginia Tech Carilion Research Institute found that small-group dynamics -- such as jury deliberations, collective bargaining sessions, and cocktail parties -- can alter the expression of IQ in some susceptible people. "You may joke about...

What happens in the brain of right-handed people if their dominant hand is immobile for two weeks? This is the question addressed in the latest study led by Professor Lutz Jäncke and the Trauma Surgery Department at Zurich University Hospital. For the study, ten right-handed people with broken upper right arms were examined. Because of the plaster or sling, the test people's right hands were restricted to little or no movement for fourteen days. Therefore they used their left...

Brain circuits for visual categorization revealed by new experiments Hundreds of times during a baseball game, the home plate umpire must instantaneously categorize a fast-moving pitch as a ball or a strike. In new research from the University of Chicago, scientists have pinpointed an area in the brain where these kinds of visual categories are encoded. While monkeys played a computer game in which they had to quickly determine the category of a moving visual stimulus, neural recordings...

Scientists Find How Our Brains Recognize Faces
2012-01-10 12:43:24

A new study by Massachusetts Institute of Technology (MIT) shines new light on how the human brain can recognize faces, as well as how it can discern actual faces from face-like images or objects. According to an MIT press release, our minds are often able to see things that resemble faces, such as the New Hampshire's "Old Man of the Mountain." Yet at the same time, rarely do we have difficulty telling the difference between these and actual faces, and Professor of Brain and Cognitive...

Pioneering vision study in mice will help revolutionize the study of brain function and mental disease There's a 3-D world in our brains. It's a landscape that mimics the outside world, where the objects we see exist as collections of neural circuits and electrical impulses. Now, scientists at the Salk Institute for Biological Studies are using new tools they developed to chart that world, a key step in revolutionizing research into the neurological basis of vision. For the first...

Complementary image processing in the cerebral hemispheres The left brain/right brain dichotomy has been prominent on the pop psychology scene since Nobel Laureate Roger Sperry broached the subject in the 1960s. The left is analytical while the right is creative, so goes the adage. And then there is the quasi-scientific obsession with "the face." Facial recognition technology and facial microexpressions are the stuff of television crime dramas, such as Person of Interest and Lie to Me....

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

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...

tesla
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
