Alzheimer's Disease
2014-08-19 03:00:23

Liz French, University of Exeter A team led by researchers at the University of Exeter Medical School and King’s College London has uncovered some of the strongest evidence yet that epigenetic changes in the brain play a role in Alzheimer’s disease. Epigenetic changes affect the expression or activity of genes without changing the underlying DNA sequence and are believed to be one mechanism by which the environment can interact with the genome. Importantly, epigenetic changes are...

schizophrenia twilight zone
2014-08-19 02:30:56

Dan Gaffney, University of Sydney People with schizophrenia struggle to turn goals into actions because brain structures governing desire and emotion are less active and fail to pass goal-directed messages to cortical regions affecting human decision-making, new research reveals. Published in Biological Psychiatry, the finding by a University of Sydney research team is the first to illustrate the inability to initiate goal-directed behavior common in people with schizophrenia. The...

Salk Institute for Biological Studies Salk researchers discover a master gene responsible for sleep and wake cycles, offering hope for a drug that could help reset sleep Scientists at the Salk Institute for Biological Studies have identified a gene that regulates sleep and wake rhythms. The discovery of the role of this gene, called Lhx1, provides scientists with a potential therapeutic target to help night-shift workers or jet lagged travelers adjust to time differences more...

April Flowers for redOrbit.com - Your Universe Online Last night you couldn't get to sleep until the wee hours, and today you can't seem to concentrate on anything. You know the two are related, but how? A new study led by NYU Langone Medical Center and funded by the National Institutes of Health (NIH) has found that just a few nerve cells in the brain may control the switch between internal thoughts and external distractions. The findings, published in Cell, may represent a breakthrough...

How The Woodpecker Avoids Brain Injury Despite High-speed Impacts
2014-08-13 03:52:28

Science China Press Designing structures and devices that protect the body from shock and vibrations during high-velocity impacts is a universal challenge. Scientists and engineers focusing on this challenge might make advances by studying the unique morphology of the woodpecker, whose body functions as an excellent anti-shock structure. The woodpecker's brain can withstand repeated collisions and deceleration of 1200 g during rapid pecking. This anti-shock feature relates to the...

2014-08-12 03:00:28

American Chemical Society No longer just fantastical fodder for sci-fi buffs, cyborg technology is bringing us tangible progress toward real-life electronic skin, prosthetics and ultraflexible circuits. Now taking this human-machine concept to an unprecedented level, pioneering scientists are working on the seamless marriage between electronics and brain signaling with the potential to transform our understanding of how the brain works — and how to treat its most devastating diseases....

3d brain tissue
2014-08-12 05:03:27

redOrbit Staff & Wire Reports - Your Universe Online A team of bioengineers from Tufts University in Massachusetts have developed three-dimensional brain-like cortical tissue that is similar in structure and function to tissues found in the brain of a rat, exhibits biochemical and electrophysiological responses, and can be kept alive in the laboratory for more than eight weeks. In research published in the August 11 early online edition of the journal Proceedings of the National...

Emory University Physicists have identified a mechanism that may help explain Zipf’s law – a unique pattern of behavior found in disparate systems, including complex biological ones. The journal Physical Review Letters is publishing their mathematical models, which demonstrate how Zipf’s law naturally arises when a sufficient number of units react to a hidden variable in a system. “We’ve discovered a method that produces Zipf’s law without fine-tuning and with very few...

Vanderbilt University Medical Center Researchers in the Vanderbilt University Institute of Imaging Science (VUIIS) have achieved the first conclusive non-invasive measurement of neural signaling in the spinal cords of healthy human volunteers. Their technique, described today in the journal eLife, may aid efforts to help patients recover from spinal cord injuries and other disorders affecting spinal cord function, including multiple sclerosis. "We definitely hope that this work can...

Boosting Insect Aggression By Altering Brain Metabolism
2014-08-08 03:18:14

University of Illinois at Urbana-Champaign Scientists report they can crank up insect aggression simply by interfering with a basic metabolic pathway in the insect brain. Their study, of fruit flies and honey bees, shows a direct, causal link between brain metabolism (how the brain generates the energy it needs to function) and aggression. The team reports its findings in the Proceedings of the National Academy of Sciences. The new research follows up on previous work from the...

Cerebellum
2013-07-29 09:48:00

The cerebellum is a section of the brain that is most in charge of cognitive functions and motor skills. Formation and Orientation The cerebellum can be found at the bottom of the brain behind the pons and below that cerebral cortex under a layer of dura mater. It is considered as a part of the "hindbrain". The cerebellum is anatomically divided into two separate hemispheres, marked by the 'vermis', a small midline zone between the left and right hemispheres. But three lobes can be...

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...
