This image, captured by researchers from the Montreal Neurological Institute andHospital, McGill University, and the University of California, shows proteins being created at the brain synapses as a memory is created. These proteins increases the strength of the synaptic connection—the connection between nerve cells—so that the memory is reinforced and easy to access. Never before has this process—essentially "making" a memory in the brain—been captured visually. The full study in which this image appeared was published the June 28 issue of Science.
