Ultrastructural studies, using all forms of electron microscopy, delineate the synaptic associations and pathways of visual system neuropils of larval and adult insects.

This organ had, heretofore, never been fully comprehended ultrastructurally nor known relative to its blood-nerve barrier. Three or four publications on this facet of our mission will come out in 1997.
