Scientists model brain structure to help computers recognize objects An essential question confronting neuroscientists and computer vision researchers alike is how objects can be identified by simply "looking" at an image. Introspectively, we know that the human brain solves this problem very well. We only have to look at something to know what it is. But teaching a computer to "know" what it´s looking at is far harder. In research published this fall in the Public Library of...

KIT Biologists Supply Major Results for Understanding the Thalamus, the “Relay Center” of the Brain The thalamus is the central translator in the brain: Specialized nerve cells (neurons) receive information from the sensory organs, process it, and transmit it deep into the brain. Researchers from the Institute of Toxicology and Genetics (ITG) of KIT have now identified the genetic factors Lhx2 and Lhx9 responsible for the development of these neurons. Their results contribute...

The study, initiated by the Swiss researchers and published in Nature, constitutes ground-breaking work in exploring emotions in the brain. Anxiety disorders constitute a complex family of pathologies affecting about 10% of adults. Patients suffering from such disorders fear certain situations or objects to exaggerated extents totally out of proportion to the real danger they present. The amygdala, a deep-brain structure, plays a key part in processing fear and anxiety. Its functioning can...

A team of physicians and scientists at Barrow Neurological Institute, in collaboration with colleagues in the Ukraine, have written a first-of-its-kind biography of Ukranian anatomist and histologist Vladimir Betz. The article, "The Discovery of the Pyramidal Neurons: Vladimir Betz and a New Era of Neuroscience," appears in the November 2011 issue of the medical journal, Brain. Among other contributions, Vladimir Alekseyevich Betz (1834-1894) is best known for his discovery of Betz cells,...

Multiple sclerosis (MS) may progress from the outermost layers of the brain to its deep parts, and isn't always an "inside-out" process as previously thought, reported a new collaborative study from researchers at the Mayo Clinic and the Cleveland Clinic. The traditional understanding is that the disease begins in the white matter that forms the bulk of the brain's inside, and extends to involve the brain's superficial layers, the cortex. Study findings support an opposite, outside-in...

Neuroimaging has provided fascinating insight into the dynamic nature of human brain maturation. However, most studies of developmental changes in brain anatomy have considered individual locations in relative isolation from all others and have not characterized relationships between structural changes in different parts of the developing brain. Now, new research describes the first comprehensive study of coordinated anatomical maturation within the developing human brain. The study,...

Primates learn from feedback that surprises them, and in a recent investigation of how that happens, neurosurgeons have learned something new. The insight they gleaned from examining the response of specific brain tissues during a learning task may inform future rehabilitative therapies after stroke or traumatic brain injury. "It's been known for a long time that it's unexpected events in particular that drive learning," said Wael Asaad, assistant professor of neurosurgery in the Warren...

Different brain structures control eye reflexes in the course of life Structures in the midbrain that developed early in evolution can be responsible for functions in newborns which in adults are taken over by the cerebral cortex. New evidence for this theory has been found in the visual system of monkeys by a team of researchers from the RUB. The scientists studied a reflex that stabilizes the image of a moving scene on the retina to prevent blur, the so-termed optokinetic nystagmus. They...

A new animal study suggests that with training, smell can improve In a new study scientists at NYU Langone Medical Center have shown that the sense of smell can be improved. The new findings, published online November 20, 2011, in Nature Neuroscience, suggest possible ways to reverse the loss of smell due to aging or disease. Smell is unique among our senses, explains Donald A. Wilson, PhD, professor of child and adolescent psychiatry at NYU Langone Medical Center and senior research...

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...
