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...

Salk Institute Salk scientists show that the little-known supportive cells are vital in cognitive function When you're expecting something—like the meal you've ordered at a restaurant—or when something captures your interest, unique electrical rhythms sweep through your brain. These waves are called gamma oscillations and they reflect a symphony of cells—both excitatory and inhibitory—playing together in an orchestrated way. Though their role has been debated, gamma waves...

sleep loss affects memory

April Flowers for redOrbit.com - Your Universe Online Going without sleep over a long period of time can be detrimental to your health in many ways, including depression, heart disease, high blood pressure, weight gain and even a lack of sex drive. WebMD cites sleeplessness as a mitigating factor in some of the largest disasters in recent history, including Three Mile Island, Chernobyl, and the Exxon Valdez oil spill. So many people suffer from a chronic lack of sleep that it is...

Washington University in St. Louis New research provides an intriguing glimpse into the processes that establish connections between nerve cells in the brain. These connections, or synapses, allow nerve cells to transmit and process information involved in thinking and moving the body. Reporting online in Neuron, researchers at Washington University School of Medicine in St. Louis have identified a group of proteins that program a common type of brain nerve cell to connect with another...

University of North Carolina Health Care UNC researchers lay the groundwork for a new approach to brain cancer treatments and a better understanding of Parkinson's disease Researchers at the UNC School of Medicine have discovered that the protein PARC/CUL9 helps neurons and brain cancer cells override the biochemical mechanisms that lead to cell death in most other cells. In neurons, long-term survival allows for proper brain function as we age. In brain cancer cells, though, long-term...

A team of researchers at the Neuroscience Institute at Georgia State University has discovered that hidden differences in the properties of neural circuits can account for whether animals are behaviorally susceptible to brain injury. These results could have implications for the treatment of brain trauma. (PRWEB) July 15, 2014 A team of researchers at the Neuroscience Institute at Georgia State University has discovered that hidden differences in the properties of neural circuits can...

Explaining Brain Circuitry By Dodging Dots

Brown University A neuroscience study provides new insight into the primal brain circuits involved in collision avoidance, and perhaps a more general model of how neurons can participate in networks to process information and act on it. In the study, Brown University neuroscientists tracked the cell-by-cell progress of neural signals from the eyes through the brains of tadpoles as they saw and reacted to stimuli including an apparently approaching black circle. In so doing, the...

Newborn Night-Waking Has A Detrimental Health Impact On Parents
2014-07-09 09:11:48

April Flowers for redOrbit.com - Your Universe Online One of the hardest parts of new parenthood is never getting enough sleep. Once an hour, every night, the baby cries out for food, comfort, or to be cleaned. Most new parents report feeling more exhausted in the morning than they did the night before. Professor Avi Sadeh led a team of researchers from Tel Aviv University's (TAU) School of Psychological Sciences to conduct the first study to examine why interrupted sleep can be as...

A new study which found visual attention deficits part of dyslexia highlights the limitations of the phonological hypothesis while supporting Dr. Harold Levinson’s cerebellar research. The latter indicates that the reading disorder in dyslexia has multiple co-determining mechanisms which respond favorably and often rapidly to cerebellar-enhancing medications and related therapies. Great Neck, NY (PRWEB) July 08, 2014 A new study just published in the journal Neurocase revealed...

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
2013-03-05 13:54:00

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...
