Age-related Memory Loss Reversed In Mice
2013-08-29 04:56:50

[ Watch the Video: New Discovery Could Lead to New Treatment for Memory Loss ] April Flowers for redOrbit.com - Your Universe Online The deficiency of a protein called RbAp48 in the hippocampus has been identified by a team of Columbia University (CUMC) researchers as a significant contributor to age-related memory loss. The team, led by Nobel laureate Eric R. Kandel, MD, also found this type of memory loss is reversible. The study, published in Science Translational Medicine, was...

Schizophrenia Genetic Origins
2013-08-26 14:28:00

Brett Smith for redOrbit.com - Your Universe Online Schizophrenia is a one of the most complex and devastating of the inherited mental disorders, and remains a significant public health concern. In a new study published in the journal Nature Genetics, an international team of researchers has identified 22 locations in the human genome that are involved in the development of the condition, including 13 that have been named for the very first time. "If finding the causes of schizophrenia...

Finding offers clue to developing treatments for misuse of illicit drugs Scientists today reported a possible basis for why food-restricted animals show increased susceptibility to drugs of abuse. This association has puzzled researchers since it was first observed more than three decades ago. Senior author Michael Beckstead, Ph.D., from the School of Medicine at The University of Texas Health Science Center San Antonio, said the team found that dopamine neurons in a brain region called...

Both Aß and tau pathology appear to be associated with default mode network integrity before clinical onset of Alzheimer disease (AD), according to a study by Liang Wang, M.D., and colleagues at Washington University in St. Louis, Missouri. Accumulation of Aß and tau proteins, the pathologic hallmarks of AD, starts years before clinical onset. Pathophysiological abnormalities in the preclinical phase of AD may be detected using cerebrospinal fluid (CSF) or neuroimaging biomarkers,...

Left Vs. Right: University Says Neither When It Comes To Brain Dominance
2013-08-19 11:11:25

Brett Smith for redOrbit.com - Your Universe Online The idea of a “left-brain” versus a “right-brain” personality has been used in a variety of contexts over the years, from interpersonal relationships to career choices. However, a new study from the University of Utah found that the idea of a dominant side of the brain affecting personality could be nonsense. Using brain imaging scans taken from over 1,000 volunteers, the Utah neuroscientists found that each side of the brain...

Dyslexia Seen In Brain Scans Pre-K
2013-08-14 11:27:14

Brett Smith for redOrbit.com - Your Universe Online Dyslexia is typically diagnosed when a child is 7 or 8 years old, but new research from MIT could help identify kids at-risk for the reading disorder before they even begin to recognize words and their meanings. Using advanced brain imaging technology, scientists at Boston Children’s Hospital have identified a connection between poor pre-reading skills in kindergartners and the size of a brain structure called the arcuate fasciculus,...

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...

Trying to explain riding a bike is difficult because it is an implicit memory. The body knows what to do, but thinking about the process can often interfere. So why is it that under certain circumstances paying full attention and trying hard can actually impede performance? A new UC Santa Barbara study, published today in the Journal of Neuroscience, reveals part of the answer. There are two kinds of memory: implicit, a form of long-term memory not requiring conscious thought and expressed...

"Pressing the button of the lift at your work place, or apartment building is an automatic action – a habit. You don't even really look at the different buttons; your hand is almost reaching out and pressing on its own. But what happens when you use the lift in a new place? In this case, your hand doesn't know the way, you have to locate the buttons, find the right one, and only then your hand can press a button. Here, pushing the button is a goal-directed action." It is...

Midbrain
2013-07-25 15:13:23

The midbrain, also known as the mesencephalon is the part of the brain most responsible for vision, motor control, arousal, temperature regulation, alertness and hearing. Formation and Orientation The midbrain is found under the cerebral cortex and above the hindbrain. The mesencephalon is not divided into any other portions of the brain unlike the other two vesicles that stem from the neural tube. There are four separate lobes on the side of the cerebral aqueduct within the...

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...
