Neuroscience

From imaging neurons to measuring their true activity

When neurons communicate with each another, they transmit—or "fire"—small electrical impulses called action potentials or spikes. These action potentials are the fundamental units of information processing in the brain. ...

Non-invasive imaging could help match leukaemia patients with treatments

Researchers at the Francis Crick Institute have identified visual changes in the bone marrow caused by acute myeloid leukemia (AML). The imaging technique used is now being tested in hospital to see if it could help predict ...

Neuroscience

New imaging measure to track brain aging

Researchers from UNSW Sydney's Centre for Healthy Brain Aging (CHeBA) have developed an improved neuroimaging measure to monitor age-related cognitive decline in older adults.

Warming of CT contrast media may not be needed

According to ARRS' American Journal of Roentgenology (AJR), the resources required to warm iohexol 350 to body temperature before injection for CT may not be warranted, given the lack of observed practical benefit.

Neuroscience

Brain fingerprints help doctors detect neurological disease

An EPFL scientist has found that brain fingerprints—or maps of the neural connections within our brain—can be used to detect a decline in cognitive ability. That's because the fingerprints are harder to detect in people ...

3D imaging reveals neural 'vicious cycle' in fatty liver disease

With the application of a novel three-dimensional imaging technology, researchers at Karolinska Institutet have discovered that one portion of the autonomic nervous system in the liver undergoes severe degeneration in non-alcoholic ...

Enhancing drug delivery with ultrasound

It can be difficult to get drugs to disease sites along the gastrointestinal tract, which spans the mouth, esophagus, stomach, small and large intestine, and anus. Invasive treatments can take hours as patients wait for adequate ...

Reducing data-transfer error in radiation therapy

Just as helicopter traffic reporters use their 'bird's eye view' to route drivers around roadblocks safely, radiation oncologists treating a variety of cancers can use new guidelines developed by a West Virginia University ...

Neuroscience

MRI's magnetic field affects focused ultrasound technology

MRI-guided focused ultrasound combined with microbubbles can open the blood-brain barrier (BBB) and allow therapeutic drugs to reach the diseased brain location under the guidance of MRI. It is a promising technique that ...
