In the brain, as in business, connections are everything. To maintain cellular associates, the outer surface of a neuron, its membrane, must express particular proteins —proverbial hands that reach out and greet nearby cells.
In an international collaboration between MedUni Vienna, Semmelweis University in Budapest, the Karolinska Institute in Stockholm and Yale University, researchers have identified a new process in the brain that is responsible for the delayed stress response and the long-term effects of stress: With a delay of 10 minutes after the ‘danger’, the area of the brain that reacts to stress and responsible for further action is activated via the cerebral fluid.
By developing a novel decoding technology, a team of engineers and physicians at the University of Southern California (USC) and UC San Francisco have discovered how mood variations can be decoded from neural signals in the human brain--a process that has not been demonstrated to date.
Researchers from the University of California San Diego have developed a fast and low-cost method of creating human cortical organoids directly from primary cells. This new protocol will allow the researchers to better understand how our own brains work.
Take a look at your favorite mug; it probably looks the same as it always has, but your neurons may not think so. Neurons are firing in response to the visual stimuli they see but they don't fire in exactly the same way every time.
Michaela Cordova, a research associate and lab manager at Oregon Health and Science University, began by ‘de-metaling’: Removing rings, watches, gadgets and other sources of metal, double-checking her pockets for overlooked objects that could, in her words, ‘fly in’. Then she entered the scanning room, raised and lowered the bed, and waved a head coil in the general direction of the viewing window and the iPad camera that’s enabling this virtual lab tour (I’m watching from thousands of miles away in Massachusetts).
The adverse impact of nicotine on health is common knowledge. A 21-year study by the University of Indonesia’s Social Security Research Center (PKJS-UI) made public in June only confirms it and reminds the government yet again to take radical action, thejakartapost.com wrote.
A new, highly accurate MRI technique can monitor iron levels in the brains of multiple sclerosis (MS) patients and help identify those at a higher risk for developing physical disability, according to a study published in the journal Radiology.
Neuroscientist Barbara Bendlin studies the brain as Alzheimer’s disease develops. When she goes home, she tries to leave her work in the lab. But one recent research project has crossed into her personal life: She now takes sleep much more seriously.
