Convergence research project integrated neurobiology with data science techniques. Using experiments and a deep machine learning data analysis approach, scientists uncovered the fundamental workings of the hippocampus region of the brain as it organizes memories into time sequences. The work could help future research into cognitive disorders such as Alzheimer’s disease and other causes of dementia.

Combining electrophysiological recording techniques in rodents with a statistical machine learning analysis of huge troves of data, the UCI researchers uncovered evidence suggesting that the hippocampal network encodes and preserves progressions of experiences to aid in decision-making. The team’s work is the subject of a paper published recently in Nature Communications.

New insights into the mechanisms of neurodegenerative diseases. Findings by researchers from Germany support the view that hyperactive immune cells in the brain can have a protective effect in the course of neurodegenerative diseases. Experts from Deutsches Zentrum für Neurodegenerative Erkrankungen (DZNE), Ludwig-Maximilians-Universität München (LMU) and LMU Klinikum München report on this in the scientific magazine The EMBO Journal. The scientists are currently considering that modulating the activity of immune cells in the brain via a receptor called TREM2 may significantly impact neurodegenerative disease processes. Thus, they see activating TREM2 as a promising approach for drug research.

The immune cells of the brain — called “microglia” — act against pathogens, help to c...

An international team led by the Case Western Reserve University School of Medicine has discovered novel properties of the protein Gasdermin B that promotes repair of cells lining the gastrointestinal tract in people with chronic inflammatory disorders like Crohn’s disease and ulcerative colitis.

The new findings, recently published in the journal, Cell, are significant because the impact of Gasdermin B (GSDMB) on healing epithelium — a type of body tissue that lines the organs that have direct contact with the external environment — will play a key role in research on wound formation and designing novel therapeutics to enhance wound repair, said Theresa Pizarro, lead study author and the Louis Pillemer Professor of Experimental Pathology at the School of Medicine...

A revolutionary pacemaker that re-establishes the heart’s naturally irregular beat is set to be trialled in New Zealand heart patients this year, following successful animal trials. “Currently, all pacemakers pace the heart metronomically, which means a very steady, even pace. But when you record heart rate in a healthy individual, you see it is constantly on the move,” says Professor Julian Paton, a lead researcher and director of Manaaki Manawa, the Centre for Heart Research at the University of Auckland.

Manaaki Manawa has led the research and the results have just been published in leading journal Basic Resear...
