Abstract
It is possible that neuronal activity may produce synaptic changes, although there has so far been no direct evidence for this. Experiments with rats suggest, however, that changes in chemistry and the structure of the synapses in the visual cortex are among the consequences of the exposure of eyes to light for the first time.
