Abstract

The influence of norepinephrine on cortical synaptogenesis was examined in the visual cortex of rats whose noradrenergic afferents were selectively eliminated with 6-hydroxydopamine. Extensive synapse counts showed a significantly higher synaptic density in the cortex of the 6-hydroxydopamine-treated rats compared to control littermates. This increase was most pronounced during the first week of postnatal life. The results suggest an inhibitory role for norepinephrine in synaptogenesis.
