Patterns of deoxyglucose and glucose labeling in the optic tectum of monocularly stimulated bass.

Uniformly labeled deoxyglucose and glucose were used to examine patterns of altered metabolic activity in the optic tectum of largemouth bass. Autoradiographs from fish which viewed moving vertical stripes with one eye show that the metabolites of the two sugars procedure similar patterns of activity-related labeling in the tectum: tangentially arranged bands of increased optical density through the SFGS and the SGC. In addition, aldehyde fixation was found to improve the histological quality of the sections without altering the patterns of labeling.
