Emotion To Vividness Of Perception Linked To Creation Of Vivid Memories
2012-08-20 13:41:57

Have you ever wondered why you can remember things from long ago as if they happened yesterday, yet sometimes can't recall what you ate for dinner last night? According to a new study led by psychologists at the University of Toronto, it's because how much something means to you actually influences how you see it as well as how vividly you can recall it later. "We've discovered that we see things that are emotionally arousing with greater clarity than those that are more mundane," says...

Study Reveals Brain's Mysterious Switchboard Operator
2012-08-17 16:08:49

A mysterious region deep in the human brain could be where we sort through the onslaught of stimuli from the outside world and focus on the information most important to our behavior and survival, Princeton University researchers have found. The researchers report in the journal Science that an area of our brain called the pulvinar regulates communication between clusters of brain cells as our brain focuses on the people and objects that need our attention. Like a switchboard operator, the...

Brain Power, Not Muscle Strength Related To Force Of Karate Punch
2012-08-16 12:29:05

Connie K. Ho for redOrbit.com — Your Universe Online Brain scans of karate experts recently showed distinctive features. Researchers believe that the images show how the ability to punch for black belts and karate novices could be related to a certain feature in the brain. The researchers, hailing from Imperial College London and University College London, discovered differences in the structure of the connection between brain regions, otherwise known as white matter. To begin,...

Scientists from The Scripps Research Institute have identified a new stem cell population that may be responsible for giving birth to the neurons responsible for higher thinking. The finding also paves the way for scientists to produce these neurons in culture–a first step in developing better treatments for cognitive disorders, such as schizophrenia and autism, which result from disrupted connections among these brain cells. Published in the August 10, 2012 issue of the journal...

Just one week of speech therapy may reorganize the brain, helping to reduce stuttering, according to a study published in the August 8, 2012, online issue of Neurology®, the medical journal of the American Academy of Neurology. The Chinese study gives researchers new insights into the role of different brain regions in stuttering, which affects about one percent of adults. The study involved 28 people with stuttering and 13 people who did not stutter. Fifteen of the people with...

Brain-boosting Proteins Triggered Through Natural Birth But Not Through C-section
2012-08-09 07:34:55

Vaginal birth triggers the expression of a protein in the brains of newborns that improves brain development and function in adulthood, according to a new study by Yale School of Medicine researchers, who also found that this protein expression is impaired in the brains of offspring delivered by caesarean section (C-sections). These findings are published in the August issue of PLoS ONE by a team of researchers led by Tamas Horvath, the Jean and David W. Wallace Professor of Biomedical...

Stressed volunteers use different strategies and brain regions Stressed and non-stressed persons use different brain regions and different strategies when learning. This has been reported by the cognitive psychologists PD Dr. Lars Schwabe and Professor Oliver Wolf from the Ruhr-Universität Bochum in the Journal of Neuroscience. Non-stressed individuals applied a deliberate learning strategy, while stressed subjects relied more on their gut feeling. "These results demonstrate...

Imaging Neural Pathways In Brain Show Intelligence Levels
2012-08-02 12:51:02

Connie K. Ho for redOrbit.com — Your Universe Online The brain is an intricate part of the body to say the least. And new research has focused on the effect of neural connectivity on one area of these intricacies, imaging a person's brain to estimate their level of intelligence. Researchers have long thought that overall brain size can affect individual variations in intelligence. A past study delved into this particular topic and demonstrated that the brain´s lateral...

The More Altruistic You Are, The More Gray Matter You Have
2012-07-11 20:45:39

The volume of a small brain region influences one's predisposition for altruistic behavior. Researchers from the University of Zurich show that people who behave more altruistically than others have more gray matter at the junction between the parietal and temporal lobe, thus showing for the first time that there is a connection between brain anatomy, brain activity and altruistic behavior. Why are some people very selfish and others very altruistic? Previous studies indicated that social...

Researchers decode a molecular mechanism that sheds light on how trauma can become engraved in the brain Feelings of anxiety very effectively prevent people from getting into situations that are too dangerous. Those who have had a terrible experience initially tend to avoid the place of tragedy out of fear. If no other oppressive situation arises, normally the symptoms of fear gradually subside. "The memory of the terrible events is not just erased." states first author, PD Dr. Andras...

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...
