Abstract We report a light‐ and electron‐microscopic examination of the inner plexiform layer of the central retina of young (c. 1 year) and old (3–4 year) goldfish. There were no new neurons added to this region during the growth period. Nonetheless, there were substantially more synapses (per cell, per mm 2 , or per degree 2 ) in the older retinas. This result is discussed in the contexts of retinal function and neural development.
