August 13, 2024 by Impact Journals, LLC Credit: Pixabay/CC0 Public DomainA new research perspective titled Lipid accumulation drives cellular senescence in dopaminergic neurons has been published in Aging. As highlighted in the Abstract of this perspective, Parkinson’s disease (PD) is an age-related movement disorder caused by the loss of dopaminergic (DA) neurons in the substantia...

August 12, 2024 by CUNY Advanced Science Research Center The stem-like cells called oligodendrocyte progenitors (red) in the adult brain are characterized by abundant histone H4 acetylation tags (green text) that regulate their proliferation and affect the size of the progenitor pool available for myelin repair. When acetylation is blocked (red text), fewer cells are...
August 12, 2024 by University of California – San Diego The lines on this diagram of the brain represent connections between various areas of the cerebral cortex involved in language processing. When we read, the neurons in these areas fire in precise synchronicity, a phenomenon known as “co-rippling.” Credit: UC San Diego Health SciencesFor decades,...

August 2, 2024 by Anke Maes, Ruhr-Universitaet-Bochum In the brain, memories are stored like books in a well-organized library, this study concludes. Credit: RUB, MarquardThe brain is constantly storing new experiences that it has to integrate into the jumble of existing memories. Surprisingly, it does not overwrite previous memory traces in the process. The first...
JULY 23, 2024 by Mass General Brigham Credit: Human Brain ProjectLate-life depression, typically defined as depression with onset in individuals over 60 years of age, can affect up to a third or more of people older than 60 and can be debilitating. But, like other neurological conditions, an individual’s risk may be influenced by lifestyle...
