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,"...

Call a bird "birdbrained" and they may call "fowl." Cornell University researchers have proven that the capacity for learning in birds is not linked to overall brain size, but to the relative size and proportion of their specific brain regions. Songbirds with upper brain regions that are larger in relation to lower regions have a greater capacity for learning songs. Higher brain areas control the majority of cognitive and learning functions, while lower brain areas control more motor...

Researchers already know that chronic misuse of alcohol can cause widespread damage to the brain. While previous studies examined cortical atrophy in individuals with alcoholism, none examined alcohol-associated atrophy using cortical thickness measurements to obtain a regional mapping of tissue loss across the full cortical surface. This study does so, finding that alcohol damage occurs in gradations: the more alcohol consumed, the greater the damage. Results will be published in the...

(Ivanhoe Newswire) -- A new study shows chronic drinking leads to reduced cortical thickness in brain regions, and the more alcohol you consume, the greater the damage. Researchers compared high-resolution structural magnetic resonance scans from 65 participants in two groups: 31 abstinent alcoholic participants and 34 nonalcoholic control participants. The images were used to create cortical-surface models. "Before advances in neuroimaging technology, the degree to which alcohol...

Access to health insurance top indicator for better outcomes among undocumented children Shakespeare famously referred to "the mind's eye," but scientists at USC now have also identified a "mind's touch." USC scientists have discovered that as you look at an object, your brain not only processes what the object looks like, but remembers what it feels like to touch it as well. This connection is so strong that a computer examining data coming only from the part of your brain that...

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...
