The brain clearing out dead neurons captured in video first
Interestingly, in aged brains the glial cells seemed to work much slower, taking up to twice as long to remove the dead neuron. This, the team says, could implicate the process in neurodegenerative diseases that come with age.
“Presumably, if cells are dying and there is inefficient removal of them, the debris could be causing further damage and inflammation,” says Jaime Grutzendler, lead researcher on the study. “ And if we can remove dying cells efficiently, can we prevent age-related neurodegeneration?”
