Harvard University Study shows that mice can identify specific odors amid complex olfactory environments For many animals, making sense of the clutter of sensory stimuli is often a matter or literal life or death. Exactly how animals separate objects of interest, such as food sources or the scent of predators, from background information, however, remains largely unknown. Even the extent to which animals can make such distinctions, and how differences between scents might affect the...

Vanderbilt University Issues of crime and punishment, vengeance and justice date back to the dawn of human history, but it is only in the last few years that scientists have begun exploring the basic nature of the complex neural processes in the brain that underlie these fundamental behaviors. Now a new brain imaging study – published online Aug. 3 by the journal Nature Neuroscience – has identified the brain mechanisms that underlie our judgment of how severely a person who has...

stress and mental illness
2014-08-02 05:31:14

Rayshell Clapper for redOrbit.com - Your Universe Online People suffer from stress under a litany of situations. Some situations are temporarily stressful and then dissipate while others lead to long-term psychological problems including post-traumatic stress disorder (PTSD). It seems that more people these days suffer from the consequences of stress, which leads to many studies about the mental illness. In one study completed by Duke University, the study's senior author Dr. Kafui...

Alan McStravick for redOrbit.com - Your Universe online An orchestra, consisting of woodwinds, strings, percussion and brass instruments, each work off a score specific to the instrument they are playing. They each contribute a layer to the overall performance that, by themselves, would paint only a limited picture of what the piece was meant to sound like. Imagine Beethoven's 5th Symphony where all you heard were the oboes playing. The conductor, standing before the full written score, is...

Cedars-Sinai Medical Center Cedars-Sinai-led investigators say some brain cells in a structure called the amygdala appear to make judgments based on a viewer's subjective opinions instead of true emotion expressed When evaluating another person's emotions – happy, sad, angry, afraid – humans take cues from facial expressions. Neurons in a part of the brain called the amygdala "fire" in response to the visual stimulation as information is processed by the retina, the amygdala and a...

child stress

redOrbit Staff & Wire Reports - Your Universe Online Chronic stressors such as poverty or abuse can have a lasting negative impact on children and could be linked to behavioral, health or employment-related problems later on in life, according to new research appearing in the latest edition of the journal Biological Psychiatry. While experiencing a certain amount of stress can help youngsters learn how to adapt to and cope with life’s obstacles, researchers from the University of...

Study Looks At Association Between Childhood Maltreatment And Volume Of Cerebral Grey Matter

FECYT - Spanish Foundation for Science and Technology Abuse could lead to permanent brain damage An international study has analyzed the association between childhood maltreatment and the volume of cerebral grey matter, responsible for processing information. The results revealed a significant deficit in various late developing regions of the brain after abuse. According to the World Health Organisation (WHO), child maltreatment is defined as all forms of physical and/or emotional...

angry face lends weight
2014-06-10 04:59:20

Brett Smith for redOrbit.com - Your Universe Online Research has found that facial expressions can convey more information than verbal communication alone and a new Harvard University study has found that an angry glare can add effectiveness to a negotiator’s demands. Published in Psychological Science, the study found that an angry glare adds additional gravity to a negotiator’s threat to walk away from the talks. The researchers also saw that the glared-at party tended to offer...

Rats Experience Regret Similar To Humans

Alan McStravick for redOrbit.com - Your Universe Online In the 2007 Disney feature length Cartoon, Ratatouille, the lead character Remy was separated from his family due to his desire to save Augesten Gusteau's restaurant after reading the famed book "You Can Cook" during the exodus from the besieged farmhouse. That fateful decision and its immediate aftermath were portrayed in such a way that we, as human viewers, were meant to sense Remy's regret. But surely, rats are incapable of such...

sight and sound in the visual cortex
2014-05-26 04:33:05

redOrbit Staff & Wire Reports - Your Universe Online While analyzing the brain processes associated with sight, researchers from the University of Glasgow have discovered that the visual cortex processes information not just from the eyes, but from the ears as well. Writing in the journal Current Biology, the study authors explain that the auditory input makes it possible for a person’s visual system to predict incoming information, thus giving them an advantage in potentially...

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...
