Superimposed transmission and fluorescence projections of a locust midbrain (exclusive optic lobes) 14 days after crush of the right antenna.

Antennal lobes are labeled with Neurobiotin. Asterisks indicate treated side. No obvious differences in antennal lobe size are visible. A. Raw data of superimposed transmission-and emission projections. B–D. Reconstructed optical sections of antennal lobes. B. Transmission. C. Emission. D. Merged. Note that Neurobiotin labels distinct glomeruli in the left (control side; arrows in C,D) but not the right (treated side) antennal lobe. AL, antennal lobe. Scale bars  = 200 µm (scale bar in D applies to B–D).
