Pruning is a process that is more important than was once believed. Experiences during infancy and childhood form the connections that shape the development of the brain. Pruning is a key part of brain development because it eliminates the connections that are not used often enough.
A newly published brain-tissue study suggests that children affected by autism have a surplus of synapses, or connections between brain cells. The excess is due to a slowdown in the normal pruning process that occurs during brain development, the researchers say. The study team also found that the medication rapamycin both restores normal synaptic pruning and reduces autism-like behaviors in a mouse model of autism.
