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...

A new study using magnetic resonance imaging data of 406 adult human twins affirms the long-standing idea that the genetic basis of human cortical regionalization — the organization of the outer brain into specific functional areas — is similar to and consistent with patterns found in other mammals, indicating a common conservation mechanism in evolution. The findings by researchers at the University of California, San Diego School of Medicine and colleagues are published in...

(Ivanhoe Newswire) -- The exact causes of autism remain unknown, but failure of a vital prenatal process may be one of the culprits. A new study, published in the November 9 issue of the Journal of the American Medical Society (JAMA), confirms this relatively recent theory. The study, by researchers at the University of California, San Diego Autism Center of Excellence, shows that brain overgrowth in boys with autism involves excess neurons in areas of the brain associated with social,...

Brain imaging experiments uncouple two apparently intimately connected mental processes In everyday life, attention and awareness appear tightly interwoven. Attending to the scissors on the right side of your desk, you become aware of their attributes, for example the red handles. Vice versa, the red handles could attract your attention to the scissors. However, a number of behavioural observations have recently led scientists to postulate that attention and awareness are fundamentally...

Motherhood is associated with the acquisition of a host of new behaviors that must be driven, at least in part, by alterations in brain function. Now, new research published by Cell Press in the October 20 issue of the journal Neuron provides intriguing insight into how neural changes associated with the integration of odors and sounds underlie a mother's ability to recognize and respond to distress calls from her pups. "We know that distinct brain changes are linked with motherhood, but...

New research suggests the growth rate of the brain's cerebral cortex in babies born prematurely may predict how well they are able to think, speak, plan and pay attention later in childhood. The research is published in the October 12, 2011, online issue of Neurology, the medical journal of the American Academy of Neurology. The cerebral cortex is the outer layer of the brain covering the cerebrum, and is responsible for cognitive functions, such as language, memory, attention and thought....

(Ivanhoe Newswire) -- The bigger the better! New research shows that may be true when dealing with the brains of premature babies. The research suggests the growth rate of a premature baby's cerebral cortex may predict how well they are able to think, speak, plan and pay attention later in childhood. "The period before a full-term birth is critical for brain development. Problems occurring at this time have long-term consequences, and it appears that preterm birth affects brain growth,"...

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...
