Strokes can leave lifelong lingering issues, as neurons are damaged and die. But now, researchers at the University of Pittsburgh Brain Institute have identified a new drug that could help prevent damage even after a stroke, with tests in mice showing promise.Continue ReadingCategory: Medical, ScienceTags: Strokes, Brain, Cells, University of Pittsburgh, Protein, Drug
New imaging research is offering detailed insights into the relationship between Alzheimer’s disease and abnormal accumulations of iron in the brain. The study confirms a distinct correlation between higher iron deposits in particular brain regions and rates of cognitive decline.Continue ReadingCategory: ScienceTags: Alzheimer's Disease, Dementia, Neuroscience, fMRI, Brain, Medical Imaging
New data chronicling the long-term effects of deep brain stimulation (DBS) on early-stage Parkinson’s disease patients has found the treatment significantly slows its progression. Researchers from Vanderbilt University Medical Center suggest, if the results are validated in a large Phase 3 trial currently underway, DBS will become the first therapy clinically proven to slow the progression of thi
The human brain reacts completely differently to a threat that invades your personal space compared to those that are further away, according to a new study that combined MRI scans with VR technology. Distant threats engage circuits in the brain linked to problem-solving, while closer dangers trigger parts the brain that deal with defensive, less reasoned animal instincts, and are more likely to
In the average human body, tens of billions of cells die everyday. It’s a natural process, important for keeping the body healthy. Now, for the first time, researchers at Yale School of Medicine have directly imaged the death of neurons in mice, as well as how the body clears them out afterwards.Continue ReadingCategory: Medical, ScienceTags: Brain, Neuroscience, Alzheimer's Disease, Dementi
Olympus announced on Wednesday that it would sell off its imaging division to Japan Industrial Partners, a private investment firm. You can catch the coverage on many sites. We got together a few of the photo folks from Madavor Media, including Imaging Resource founder Dave Etchells, Imaging Resource managing editor Dave Pardue, Imaging Resource senior editor William Brawley, Outdoor Photographer
Artificial synapses are an important step towards emulating the supercomputer that is the human brain. Now scientists have successfully bridged the gap between organic and artificial, with biohybrid synapses that let living cells communicate with electronic systems, not with electrical signals but with neurotransmitters like dopamine.Continue ReadingCategory: Computers, TechnologyTags: Computers,
When it comes to monitoring electrical activity in the brain, patients typically have to lie very still inside a large magnetoencephalography (MEG) machine. That could be about to change, though, as scientists have developed a new version of a wearable helmet that does the same job.Continue ReadingCategory: Medical, ScienceTags: University of Nottingham, University College London, Brain, Helmets
A milestone study published in the journal Nature Communications is offering the first demonstration of a direct causal relationship between the gut microbiome and a human neurovascular disease. Verifying prior animal studies, the research suggests a microbiome metabolite can travel through the bloodstream, reach blood vessels in the brain and expedite the development of lesions.Continue ReadingC
New research from scientists at Yale University is offering novel insights into how our brains generate acute subjective feelings of stress. The imaging study illustrates exactly which neural network seems to activate sensations of stress, raising the possibility of future therapeutic interventions that could moderate particular brain activity in subjects with mental health disorders.Continue Rea
