eye hand coordination
2014-08-05 03:30:55

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...

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
2014-07-09 03:49:18

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...

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...

mallemaroking
  • Nautical, the visiting and carousing of sailors in the Greenland ships.
This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
