Space Around Other People Perceived Just As Our Own
2013-09-05 16:14:56

Karolinska Institutet A study from Karolinska Institutet in Sweden has shown that neurons in our brain 'mirror' the space near others, just as if this was the space near ourselves. The study, published in the scientific journal Current Biology, sheds new light on a question that has long preoccupied psychologists and neuroscientists regarding the way in which the brain represents other people and the events that happens to those people. "We usually experience others as clearly separated...

Brain Controls Volume Of Voices In Your Head
2013-09-04 10:24:06

Brett Smith for redOrbit.com - Your Universe Online During a conversation, the brain constantly makes adjustments in order to efficiently process the speech volume of others while recognizing self-made speech for what it is. According to a new report published this week in The Journal of Neuroscience, Duke researchers have mapped the complex brain interactions responsible for the ability to hold a conversation or play a musical instrument. What's more, the team believes that their...

Scientists Grow Mini Brain In Lab
2013-08-29 10:58:22

Michael Harper for redOrbit.com - Your Universe Online In the ongoing quest to better understand the human brain, scientists from the Austrian Academy of Sciences have been growing their own mini brains. These small collections of tissue aren’t capable of thought and are much smaller than a fully developed brain, but scientists say they’re still very valuable research tools. The brain matter began life as stem cells suspended in gel, which were then submerged into a solution of...

Scientists at The Scripps Research Institute (TSRI) have decoded an important molecular signal that guides the development of a key region of the brain known as the neocortex. The largest and most recently evolved region of the brain, the neocortex is particularly well developed in humans and is responsible for sensory processing, long-term memory, reasoning, complex muscle actions, consciousness and other functions. "The mammalian neocortex has a distinctive structure featuring six layers...

Salk-Gladstone Study Helps Scientists Decode Circuitry That Guides Brain Function
2013-06-28 09:51:01

Salk Institute The power of the brain lies in its trillions of intercellular connections, called synapses that together form complex neural "networks." While neuroscientists have long sought to map these individual connections to see how they influence specific brain functions, traditional techniques have been unsuccessful. Now, scientists at the Salk Institute and the Gladstone Institutes, using an innovative brain- tracing technique, have found a way to untangle these networks. These...

Faulty Connections In Autistic Brains
2013-06-26 09:39:07

April Flowers for redOrbit.com - Your Universe Online New light is being shed on the effects autism has on the brain by a group of researchers from San Diego State University’s Brain Development Imaging Laboratory. According to the findings, the connection between the thalamus – a deep brain structure critical to sensory and motor functions – and the brain’s outer layer known as the cerebral cortex is impaired in children with autism spectrum disorders (ASD). This first of...

3-D Roadmap Of The Human Brain
2013-06-21 06:05:12

redOrbit Staff & Wire Reports - Your Universe Online Researchers in Germany and Canada have created a spectacular 3-D digital reconstruction of a complete human brain that reveals unprecedented detail. The map, dubbed the BigBrain, has a spatial resolution just 20 microns "smaller than the size of one fine strand of hair" and represents the first time that human brain anatomy has been shown in such ultra-high resolution. Until recently, reference brains did not show much beyond...

Blood vessels within a sensory area of the mammalian brain loop and connect in unexpected ways, a new map has revealed. The study, published June 9 in the early online edition of Nature Neuroscience, describes vascular architecture within a well-known region of the cerebral cortex and explores what that structure means for functional imaging of the brain and the onset of a kind of dementia. David Kleinfeld, professor of physics and neurobiology at the University of California, San...

Early Differentiation Of Higher Brain Structures Affected By Competing Pathways
2013-04-26 11:36:30

Georgia Institute of Technology Sand-dwelling and rock-dwelling cichlids living in East Africa's Lake Malawi share a nearly identical genome, but have very different personalities. The territorial rock-dwellers live in communities where social interactions are important, while the sand-dwellers are itinerant and less aggressive. Those behavioral differences likely arise from a complex region of the brain known as the telencephalon, which governs communication, emotion, movement and...

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...
