Bilaterally asymmetrical uptake of [14C]2-deoxyglucose by the octavo-lateralis complexes in flatfish.

[14C]2-deoxyglucose uptake by neurons located in the octavolateralis complex of adult flatfish is asymmetrical on the two sides of the brain. It appears that the neuronal activity on the side oriented upward is higher than that on the side of the brain facing downward. This finding may be significant with respect to the mechanisms of metamorphosis of flatfish and may account for the peculiar fact that these animals swim on one body side during adult live.
