Socialness In Carnivores Linked To Size Of Frontal Cortex
2013-10-09 05:49:36

April Flowers for redOrbit.com - Your Universe Online A growing body of research from Michigan State University reveals that the region of the brain that makes humans and primates social creatures may play a similar role in carnivores. Sharleen Sakai, professor of neuroscience, has studied spotted hyenas, lions, and most recently the raccoon family to find a correlation between the size of the animals' frontal cortex and their social nature. The current study, published in the journal...

Chronic Dizziness May Be Helped By Magnetic Stimulation
2013-10-09 04:55:36

redOrbit Staff & Wire Reports - Your Universe Online Researchers from the Johns Hopkins University School of Medicine believe that they have located a specific site in the human brain that could be one of the sources of dizziness and spatial disorientation. While dizziness can also be linked to damage to the inner ear, or to other senses such as vision, neurology instructor Dr. Amir Kheradmand and his colleagues report that they have discovered a region of the brain that plays a...

Inhibitory neuron type found to specifically suppress activation of other inhibitory neurons in cerebral cortex The cerebral cortex contains two major types of neurons: principal neurons that are excitatory and interneurons that are inhibitory, all interconnected within the same network. New research now reveals that one class of inhibitory neurons – called VIP interneurons -- specializes in inhibiting other inhibitory neurons in multiple regions of cortex, and does so under specific...

Einstein's Brain Was Apparently Very Well-Connected

[ Watch the Video: Dissecting Einstein's Brain ] redOrbit Staff & Wire Reports - Your Universe Online Albert Einstein is generally recognized as one of the greatest thinkers of the 20th century, but exactly what was it that made his brain so special? The authors of a recently published study believe that they have found the answer to that riddle. Writing in the journal Brain, Weiwei Men of East China Normal University's Department of Physics and his colleagues explained that the...

Area Of The Brain That Creates Illusory Shapes And Surfaces Discovered By Scientists
2013-10-01 11:10:48

Vanderbilt University The logo of the 1984 Los Angeles Olympics includes red, white and blue stars, but the white star is not really there: It is an illusion. Similarly, the "S" in the USA Network logo is wholly illusory. Both of these logos take advantage of a common perceptual illusion where the brain, when viewing a fragmented background, frequently sees shapes and surfaces that don't really exist. "It's hallucinating without taking drugs," said Alexander Maier, assistant...

Brain Circuitry Binge Eating
2013-09-27 08:27:03

redOrbit Staff & Wire Reports - Your Universe Online Researchers at University of North Carolina have identified a part of the brain that may play a critical role in eating disorders such as anorexia and bulimia. The scientists were able to pinpoint the precise cellular connections responsible for triggering this behavior, something that could give insight into a potential cause of obesity and perhaps lead to better treatments for anorexia, bulimia, and binge eating disorder – the...

Several studies have shown that expecting a reward or punishment can affect brain activity in areas responsible for processing different senses, including sight or touch. For example, research shows that these brain regions light up on brain scans when humans are expecting a treat. However, researchers know less about what happens when the reward is actually received—or an expected reward is denied. Insight on these scenarios can help researchers better understand how we learn in general....

'Odor is a means of chemical communication between mother and child' -- Johannes Frasnelli, University of Montreal What woman has not wanted to gobble up a baby placed in her arms, even if the baby is not hers? This reaction, which everyone has noticed or felt, could have biological underpinnings related to maternal functions. For the first time, an international team of researchers has found evidence of this phenomenon in the neural networks associated with reward. "The olfactory -- thus...

Bird Brain Map Gets Major Revisions

Brett Smith for redOrbit.com - Your Universe Online Using state-of-the-art genetic and diagnostic tools, researchers from Duke University and the University of California, San Diego have re-contextualized the map of the avian brain, as described to two separate papers published in the Journal of Comparative Neurology. The researchers noted many similarities between the avian brain and mammalian brain – leading them to conclude that all vertebrates have more in common with respect to...

'Love Hormone' Oxytocin May Help Autistic Children Experience Reward
2013-09-12 07:36:37

redOrbit Staff & Wire Reports - Your Universe Online Researchers at the Stanford University have shown that oxytocin, the so-called “love hormone,” is involved in a wider range of social interactions than previously understood, findings that may have implications for neurological disorders such as autism as well as scientific conceptions of our evolutionary heritage. Scientists estimate that the advent of social living preceded the emergence of pair living by about 35 million...

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...
