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...

Highly Decorated Navy SEAL Raises Funds for TBI Treatment at Carrick Irving, TX (PRWEB) August 07, 2014 Over the next nine months, retired Navy Senior Chief Mike Day will be raising funds to provide his fellow wounded warriors with access to leading edge treatment programs for debilitating brain injuries. Mike Day served over twenty-one years in the SEAL Teams leading his men into battle. On his final mission in Iraq, Mike’s men stacked behind him as he led his team into a twelve by...

Salk Institute Scientists hope to borrow strategy from simpler animals to repair damaged spinal cord nerves in humans Frogs, dogs, whales, snails can all do it, but humans and primates can't. Regrow nerves after an injury, that is—while many animals have this ability, humans don't. But new research from the Salk Institute suggests that a small molecule may be able to convince damaged nerves to grow and effectively rewire circuits. Such a feat could eventually lead to therapies for the...

Our Brains Can Judge A Face's Trustworthiness Even When We Can't See It
2014-08-07 03:47:28

New York University Our brains are able to judge the trustworthiness of a face even when we cannot consciously see it, a team of scientists has found. Their findings, which appear in the Journal of Neuroscience, shed new light on how we form snap judgments of others. "Our findings suggest that the brain automatically responds to a face's trustworthiness before it is even consciously perceived," explains Jonathan Freeman, an assistant professor in New York University's Department of...

eye hand coordination

Marlene Cimons, National Science Foundation Research helps understand how brain systems interact to carry out cognitive processes People not only use their eyes to see, but also to move. It takes less than a fraction of a second to execute the loop that travels from the brain to the eyes, and then to the hands and/or arms. Bijan Pesaran is trying to figure out what occurs in the brain during this process. "Eye-hand coordination is the result of a complex interplay between two systems...

Ecole Polytechnique Fédérale de Lausanne Neurons are the cells of our brain, spinal cord, and overall nervous system. They form complex networks to communicate with each other through electrical signals that are carried by chemicals. These chemicals bind to structures on the surface of neurons that are called neuroreceptors, opening or closing electrical pathways that allow transmission of the signal from neuron to neuron. One neuroreceptor, called 5HT3-R, is involved in conditions like...

MPG Max Planck researchers show that two products of the gene DJ-1 can increase the survival of neurons Parkinson’s disease affects neurons in the Substantia nigra brain region – their mitochondrial activity ceases and the cells die. Researchers at the Max Planck Institute of Molecular Cell Biology and Genetics show that supplying D-lactate or glycolate, two products of the gene DJ-1, can stop and even counteract this process: Adding the substances to cultured HeLa cells and to...

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...

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...
