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...

Scientists Probe Source Of A Pulsing Signal In The Sleeping Brain
2013-04-18 13:35:40

Technische Universitaet Muenchen New findings clarify where and how the brain's "slow waves" originate. These rhythmic signal pulses, which sweep through the brain during deep sleep at the rate of about one cycle per second, are assumed to play a role in processes such as consolidation of memory. For the first time, researchers have shown conclusively that slow waves start in the cerebral cortex, the part of the brain responsible for cognitive functions. They also found that such a wave...

Migraines Linked To Abnormalities In Brain Cortex
2013-03-27 08:35:24

Alan McStravick for redOrbit.com - Your Universe Online The prevailing science on the subject of migraine headaches had long recognized that certain people are simply more likely to be afflicted by this potentially debilitating condition than others. In fact, the Mayo Clinic details a handful of risk factors that can make someone more or less likely to experience migraines. Among the recognized risk factors are family history, age, gender and hormonal changes. While these and other risk...

A region of the brain known to play a key role in visual and spatial processing has a parallel function: sorting visual information into categories, according to a new study by researchers at the University of Chicago. Primates are known to have a remarkable ability to place visual stimuli into familiar and meaningful categories, such as fruit or vegetables. They can also direct their spatial attention to different locations in a scene and make spatially-targeted movements, such as...

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...

call-note
  • The call or cry of a bird or other animal to its mate or its young.
'Call-note' is newer than 'bird-call,' which originally referred to 'an instrument for imitating the note of birds' but now also refers to 'the song or cry of a bird.'
