Understanding How Neurons Get Wired
2013-08-15 09:27:33

University of Arizona Two different versions of the same signaling protein tell a nerve cell which end is which, UA researchers have discovered. The findings could help improve therapies for spinal injuries and neurodegenerative diseases. University of Arizona scientists have discovered an unknown mechanism that establishes polarity in developing nerve cells. Understanding how nerve cells make connections is an important step in developing cures for nerve damage resulting from spinal...

Researchers at Johns Hopkins have uncovered a protein switch that can either increase or decrease memory-building activity in brain cells, depending on the signals it detects. Its dual role means the protein is key to understanding the complex network of signals that shapes our brain's circuitry, the researchers say. A description of their discovery appears in the July 31 issue of the Journal of Neuroscience. "What's interesting about this protein, AGAP3, is that it is effectively...

A team of neuroscientists has identified a modification to a protein in laboratory mice linked to conditions associated with Alzheimer's Disease. Their findings, which appear in the journal Nature Neuroscience, also point to a potential therapeutic intervention for alleviating memory-related disorders. The research centered on eukaryotic initiation factor 2 alpha (eIF2alpha) and two enzymes that modify it with a phosphate group; this type of modification is termed phosphorylation. The...

A boost in the speed of brain scans is unveiling new insights into how brain regions work with each other in cooperative groups called networks. Scientists at Washington University School of Medicine in St. Louis and the Institute of Technology and Advanced Biomedical Imaging at the University of Chieti, Italy, used the quicker scans to track brain activity in volunteers at rest and while they watched a movie. “Brain activity occurs in waves that repeat as slowly as...

Baby Owls Seen Sleeping Like Baby Humans
2013-08-02 08:24:01

AlphaGalileo Foundadtion Baby birds have sleep patterns similar to baby mammals, and their sleep changes in the same way when growing up. This is what a team from the Max Planck Institute for Ornithology and the University of Lausanne found out working with barn owls in the wild. The team also discovered that this change in sleep was strongly correlated with the expression of a gene involved in producing dark, melanic feather spots, a trait known to covary with behavioral and physiological...

After Stroke, Magnetic Brain Stimulation Helps With Speech Therapy
2013-07-29 05:23:15

redOrbit Staff & Wire Reports - Your Universe Online Stroke patients who have parts of their brain stimulated with a magnetic coil prior to taking part in speech and language therapy made three times as much progress than those who did not undergo the procedure, according to research recently published in the journal Stroke. By using a non-invasive technique to temporarily shut down the parts of the brain that function properly, researchers from McGill University in Montreal...

Electrooculography
2012-12-31 11:47:45

Electrooculography, sometimes shortened to EOG, is the tracing of electricity used for operation of the retina in different phases, specifically the resting potential. The results are recorded on an electrooculogram. These are interpreted for opthalmological diagnosis and in recording eye movements. Eye movement measurements: Usually, pairs of electrodes are placed either above and below the eye or to the left and right of the eye. If the eye is moved from the center position towards one...
