Neuroscience biweekly vol. 20, 15th November - 30th NovemberTL;DR
-Scientists have developed a chip that is powered wirelessly and can be surgically implanted to read neural signals and stimulate the brain with both light and electrical current. The technology has been demonstrated successfully in rats and is designed for use as a research tool.
-New research has shown that the antidepressant sertraline helps to inhibit the growth of cancer cells. The substance acts on a metabolic addiction that allows different types of cancer to grow. This is shown by a study on cell cultures and lab animals performed by various research labs of KU Leuven.
-A genetic modification in the 'coat' of a brain infection-causing virus may allow it to escape antibodies, according to Penn State College of Medicine researchers. They say testing people for this and other viral mutations may help identify patients at risk for developing a fatal brain disease.
-While the broad architecture and organization of the human brain is universal, new research shows how the differences between how people reimagine common scenarios can be observed in brain activity and quantified. These unique neurological signatures could ultimately be used to understand, study, and even improve treatment of disorders such as Alzheimer's disease.
-New research into how a common parasite infection alters human behavior could help development of treatments for schizophrenia and other neurological disorders. T. gondii currently infects 2.5 billion people worldwide and causes the disease Toxoplasmosis.
-Scientists say a drug originally developed to treat high blood pressure can reduce severe withdrawal symptoms for patients diagnosed with alcohol use disorder. In a double-blind study, researchers gave the drug prazosin or a placebo to 100 people entering outpatient treatment after being diagnosed with alcohol use disorder. All of the patients had experienced varying degrees of withdrawal symptoms prior to entering treatment.
-Researchers have identified a protein called Wipi3 that is essential for cellular waste disposal via the alternative autophagy system. Deletion of Wipi3 in the brains of mice causes growth and motor defects attributed to neuronal accumulation of iron, resulting in neurodegeneration. However, over-expression of another alternative autophagy protein, Dram1, reverses the effects in Wipi3 deficiency, and may represent a novel treatment for neurodegenerative diseases.
-Learning a language later in life changes how the two halves of the brain contribute. As skills improve, language comprehension changes hemisphere specialization, but production does not, according to new research.
-Our ability to pay attention, plan, and troubleshoot involve cognitive processing by the brain's prefrontal cortex. The balance of activity among excitatory and inhibitory neurons in the cortex, based on local neural circuits and distant inputs, is key to these cognitive functions. A recent study shows that excitatory inputs from the thalamus activate a local inhibitory circuit in the prefrontal cortex, revealing new insights into how these cognitive circuits may be controlled.
-In a brand new study published in Current Biology, a group of researchers has explored this potential role of oxytocin and the underlying mechanisms in modulating male sexual function using rats as a model system.
-Older women who live in locations with higher levels of air pollution may have more brain shrinkage, the kind seen in Alzheimer's disease, than women who live in locations with lower levels, according to a new study. The study looked at fine particle pollution and found that breathing in high levels of this kind of air pollution was linked to shrinkage in the areas of the brain vulnerable to Alzheimer's disease.
