Astrocytes have long been considered as mere support cells for neurons. In recent years, the study of astrocytes has grown, gradually revealing their importance in brain function. Researchers from Inserm, CNRS and Collège de France at the Center for Interdisciplinary Research in Biology have now uncovered their crucial role in closing the period of brain […]
Astrocytes eat connections to maintain plasticity in adult brains
Developing brains constantly sprout new neuronal connections called synapses as they learn and remember. Important connections—the ones that are repeatedly introduced, such as how to avoid danger—are nurtured and reinforced, while connections deemed unnecessary are pruned away. Adult brains undergo similar pruning, but it was unclear how or why synapses in the adult brain get […]
