Stress During Infancy Affects Brain Development Of Females
2012-11-13 06:16:34

Connie K. Ho for redOrbit.com — Your Universe Online Researchers from the University of Wisconsin-Madison recently discovered that early family stress during infancy could be related to changes that occur in the daily brain function and anxiety of teenage girls. The data was pooled from a population study that looked at the relationship between stress and the developmental pathway of the brain. For female infants who lived in homes with stressed out mothers, they were more likely...

Researchers supported by the Wellcome Trust have discovered that we use a different part of our brain to learn about social hierarchies than we do to learn ordinary information. The study provides clues as to how this information is stored in memory and also reveals that you can tell a lot about how good somebody is likely to be at judging social rank by looking at the structure of their brain. Primates (and people) are remarkably good at ranking each other within social hierarchies, a...

Alan McStravick for redOrbit.com - Your Universe Online Two similar scenarios, but for the timing involved, require different parts of your brain to help you make a decision. Let´s say you are driving on the freeway when the car in front of you blows a tire. You have only milliseconds to process the situation, make your decision and act. Do you slam on your brakes or pull out of the lane suddenly? Either decision could be right or wrong. Scenario 2 has you driving down the same...

Jedidiah Becker for redOrbit.com — Your Universe Online In 2005, Norwegian researchers discovered a previously unknown type of neuron by placing electrodes deep within the cerebral cortex of rats. Dubbed “grid cells,” these specialized neurons were so named because they fire in distinct clusters, each of which constitutes the vertex of a grid-like pattern of equilateral triangles. This recurring triangular, lattice-like firing pattern is what distinguishes grid cells from other...

Emotional Communication Uses Sense Of Smell
2012-11-06 12:58:08

April Flowers for redOrbit.com - Your Universe Online While is it well known that many species transmit information via chemical signals, the extent to which these chemosignals play a role in human communication is unknown. Researchers from Utrecht University in the Netherlands have investigated whether we humans might actually be able to communicate with each other about our emotional states through chemical signals. The findings of the study were recently published in the journal...

Brain's code for visual working memory deciphered in monkeys -- NIH-funded study The brain holds in mind what has just been seen by synchronizing brain waves in a working memory circuit, an animal study supported by the National Institutes of Health suggests. The more in-sync such electrical signals of neurons were in two key hubs of the circuit, the more those cells held the short-term memory of a just-seen object. Charles Gray, Ph.D., of Montana State University, Bozeman, a grantee of...

UC Santa Barbara has reported an important discovery in the interdisciplinary study of split-brain research. The findings uncover dynamic changes in brain coordination patterns between left and right hemispheres. Split-brain research has been conducted for decades, and scientists have long ago shown that language processing is largely located in the left side of the brain. When words appear only in the left visual field —— an area processed by the right side of the brain...

There are a growing number of clues that immune and inflammatory mechanisms are important for the biology of schizophrenia. In a new study in Biological Psychiatry, Dr. Mar Fatjó-Vilas and colleagues explored the impact of the interleukin-1β gene (IL1β) on brain function alterations associated with schizophrenia. Fatjó-Vilas said that "this study is a contribution to the relatively new field of 'functional imaging genetics' which appears to be...

Prefrontal Cortex Controls Habits
2012-10-30 19:33:47

Lee Rannals for redOrbit.com — Your Universe Online Neuroscientists have identified a region of the brain that is capable of switching between new and old habits. A new study by MIT neuroscientists has found a wall region of the brain's prefrontal cortex is responsible for moment-by-moment control of which habits are switched on at a given time. “We´ve always thought – and I still do – that the value of a habit is you don´t have to think about it. It...

Monkeys Deconstruct The World Through Triangular Grids
2012-10-29 09:16:42

Brett Smith for redOrbit.com - Your Universe Online Researchers at Emory University have shown that some primates visually deconstruct the world through triangular grids. According to their report in the journal Nature, the scientists have identified grid cells in the brains of rhesus monkeys that fire in triangular patterns as their eyes scan a scene. Uncovering this brain activity in primates could have larger ramifications as the grid cells are connected to how we view and recall...

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...
