Summary: Researchers have identified a unique mitochondrial process in CA2 neurons that supports learning, memory, and social recognition. Mitochondria in different parts of these neurons vary in structure and function, with those at the outermost synapses relying on the mitochondrial calcium uniporter (MCU) for plasticity.Deleting the MCU gene disrupted this...

Summary: Scientists have discovered that neural stem cells (NSCs) receive constant feedback from their daughter cells, influencing whether they remain dormant or activate to form new neurons and glia. This parent-child relationship helps regulate brain regeneration and repair.The study also reveals that calcium signaling plays a key role in how...
