synaptic pruning

Learning is physical. Learning means the modification, growth, and pruning of our neurons, connections-called synapses- and neuronal networks, through experience…we are cultivating our own neuronal networks.

A genetic breakthrough could help treat schizophrenia 

Experts have long struggled to pinpoint schizophrenia biological roots — until now. After a widespread genetic analysis of 65,000 people, researchers from the Broad Institute’s Stanley Center for Psychiatric Research, Harvard Medical School, Boston Children’s Hospital and Massachusetts General Hospital found an increased risk of schizophrenia among people with a particular variant of a gene called “complement component 4,” or C4. C4 plays a role in a biological process called “synaptic pruning.”
