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...

Researchers of the Department of Biosystems Science and Engineering of ETH Zurich were able to measure the speed of neuronal signal conduction along segments of single axons in neuronal cultures by using a high-resolution electrical method. The bioengineers are now searching for plausible explanations for the large conduction speed variations. To write this little piece of text, the brain sends commands to arms and fingers to tap on the keyboard. Neuronal cells with their cable-like...

Deep brain stimulation therapy blocks or modulates electrical signals in the brain to improve symptoms in patients suffering from movement disorders such as Parkinson's disease, essential tremor and dystonia, but a new study suggests that several factors may cause electrical current to vary over time. Led by Michele Tagliati, MD, director of Cedars-Sinai Medical Center's Movement Disorders Program, the study identified variables that affect impedance – resistance in...

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...
