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

<p>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).</p>
