Medical Xpress: Brain pathways of aversion identified

What happens in the brain when we feel discomfort? Researchers at Karolinska Institutet in Sweden are now one step closer to finding the answer. In a new study published in the journal Molecular Psychiatry, they identify which pathways in the mouse brain control behaviour associated with aversion.

Spectrum: Stabilizing head mold leads to sharper brain images

A customizable Styrofoam head mold minimizes movements during brain scans, enabling researchers to produce clearer images. During a typical functional magnetic resonance imaging (fMRI) scan, researchers take multiple pictures of a person’s brain and combine them. If the person’s head moves during the scan, the images may blur and taint the results. The problem is […]

Quartz: Research shows your brain physically ages faster when you’re depressed

New research out of Yale University shows depression can physically change a person’s brain, hastening an aging effect that might leave them more susceptible to illnesses associated with old age. Scientists have, in this past, found all sorts of evidence to show how depression impacts the brain and other parts of the body. (February 15, […]

Science Daily: ‘Lack of cleaning’ in brain cells is central to Alzheimer’s disease

An international research team has created a better understanding of Alzheimer’s. They have shown that the cleaning system of the brain cells, the so-called mitophagy, is very weakened in animals and humans with Alzheimer’s. And when they improve the cleaning system in the animals, the Alzheimer’s symptoms almost disappear. (February 14, 2019) Read the full […]

Science Daily: When good cells go bad: Regulating the MS-causing properties of Th17 cells

Multiple sclerosis (MS) and other inflammatory autoimmune diseases are characterized by localized inflammation in various tissues, including the brain. Using a mouse model of MS, a team has identified a major regulator of Th17 cell-associated pathogenic inflammatory processes. The protein, Satb1, enhances the expression of genes promoting inflammation and suppresses genes needed to prevent autoimmunity. […]

Medical News Today: Alzheimer’s: How do tau tangles grow?

New research in the Journal of Biological Chemistry breaks down the process through which tau tangles grow as long as they do. The findings may lead to new therapies that target the formation of tau aggregates in Alzheimer’s disease. One of the hallmarks of Alzheimer’s disease is the so-called tau tangles. Tau is a protein […]

News-Medical: Relapse dreams more common in people with severe alcohol, drug addiction history

Vivid dreams involving drinking and drug use are common among individuals in recovery. A study from the Massachusetts General Hospital (MGH) Recovery Research Institute, published in the January issue of the Journal of Substance Abuse Treatment after online release in October 2018, finds these relapse dreams are more common in those with more severe clinical […]

Futurism: New drug combo could repair the brains of Alzheimer’s patients

Neurons receive, process, and transmit all the impulses in our brains. Essentially, they’re the building blocks of the human nervous system, and once they’re damaged by Alzheimer’s disease or some other brain injury, they’re done for — they have no regenerative abilities.
