Neuroscience: The brain's garbage men
Helmut Kettenmann1
Abstract
Microglial cells, the immune elements of the brain, are activated in disease or following injury. New findings indicate how these cells are switched on to remove damaged cells and cellular debris.
Brain function is generally considered as the activity of the neuronal network. So brain dysfunction or damage is thought to be caused by a disturbance to this network through the loss or malfunction of neurons.
