How the neuron sprouts its branches

.... To explore the role of Golgi outposts, they used imaging of living rat brain cells grown in culture, as well as electron microscopy of rat brain tissue. These studies revealed that the Golgi outposts tended to appear in longer dendrites and also that those Golgi in the main cell body tended to orient towa...

Penn researchers study the use of ultrasound for treatment of cancer

... For years, ultrasound has been used for clinical imaging and for therapeutic action in physical therapy. But now, Sehgal explains, "These results are extremely encouraging. They raise the possibility that, in the future, treatments with ultrasound either alone or with chemotherapeutic and antivascular agen...

Young scientists turn to gel to ease side-effects of cancer treatment

... Magnetic Resonance Spectroscopy can be used as an imaging technique allowing the tumour to be identified accurately, because of the differing biological activity in tumour cells compared with healthy cells. A phantom is required to prove the accuracy of these measurements. The team has already supplied sam...

Meditation associated with structural changes in brain

...ociated with attention and sensory processing. An imaging study led by Massachusetts General Hospital (MGH) researchers showed that particular areas of the cerebral cortex, the outer layer of the brain, were thicker in participants who were experienced practitioners of a type of meditation commonly practice...

Brain activity related to processing faces is similar in people with, without autism

New brain imaging research at the University of North Carolina at Ch... clear-cut finding," Belger said. Previous brain imaging findings of under-responsiveness in the facial area have led some experts to consider this a key cau...

Bigger brain size matters for intellectual ability

...y in considering the likely future use of magnetic imaging (or MRIs) of brain structure as a measure of ability in student and workforce settings. "We're going to need to be careful if, in the future, we use MRI brain scans as a measure of ability in any selection process," she said. ...

Nanoparticles, nanoshells, nanotubes: How tiny specks may provide powerful tools against cancer

...in, is the first to demonstrate how nanoshells and imaging can be used together to treat tumors in animal mod... nanoparticles has promising applications for both imaging and treatment at the same time, and might also be used to monitor treatment responses in breast canc...

Researchers develop new method for studying 'mental time travel'

...ues used Princeton's functional magnetic resonance imaging (fMRI) scanner to capture the participants' brain activity patterns as they studied the images. They then trained a computer program to distinguish between the patterns of brain activity associated with studying faces, locations or objects. The comp...

MIT researcher finds neuron growth in adult brain

...earch affiliate -- used a method called two-photon imaging to track specific neurons over several weeks in th...e help of technology similar to magnetic resonance imaging (MRI), but at a much finer, cellular resolution, the researchers were able to stitch together two-di...

Bacteria which sense the Earth's magnetic field

...attraction. But using modern molecular-genetic and imaging processes, researchers from the Max Planck Institue for Marine Microbiology in Bremen and Max Planck Institute of Biochemistry in Martinsried, Germany have identified the protein responsible for creating the magnetosome chain. The scientists showed t...

A new window into structural plasticity in the adult visual cortex

...ch tip more than doubled its length and exited the imaging volume." One nonpyramidal neuron even showed a few new branch tip additions. The authors conclude that the cortical neurons have different dynamic properties. The branch tips of interneurons in the adult neocortex can grow, retract, and sprout new a...

Logging doubles threat to the Amazon, rivaling clear-cutting, study suggests

...ar space for farming or grazing. A new satellite imaging method, developed by Gregory Asner of the Carnegie Institution of Washington and colleagues, detects deforestation on a finer scale, allowing researchers to identify areas where trees have been thinned, due mostly to "selective logging." In this type...

Research Permits First-Ever Visualization of Psychological Stress in the Human Brain

...lopment of this technique, and its applications to imaging brain-function during cognitive and emotional processes. The study was sponsored by grants from the National Science Foundation, the National Institutes of Health, and the U.S. Air Force. In addition to Drs. Wang and Detre, the team of investigators...
