Dynamical constraints on neural population activity

by Clinical Neuropsychologist | Friday, January 17, 2025 | Neuroscience

Nature Neuroscience, Published online: 17 January 2025; doi:10.1038/s41593-024-01845-7Oby, Degenhart, Grigsby and colleagues used a brain–computer interface to challenge monkeys to override their natural time courses of neural activity. They found the time courses to...

Propagation of neuronal micronuclei regulates microglial characteristics

by Clinical Neuropsychologist | Friday, January 17, 2025 | Neuroscience

Nature Neuroscience, Published online: 17 January 2025; doi:10.1038/s41593-024-01863-5Neuronal micronuclei are transferred to microglia during the early postnatal period, which leads to altered microglial morphology and transcriptomic signatures, suggesting that these...
