Experimental setup for honeybee brain imaging. Setup for the honeybee imaging experiments. After excitation with light at wavelengths 340 nm and 380 nm (light source not shown), fluorescence is recorded by a CCD camera mounted on top of a confocal microscope. Temperature is controlled by a heat lamp. The photograph shows the setup before the experiment, which is carried out in the dark. During the experiment, camera signals are processed in real time and results are displayed on the visualisation screen. Odour stimuli can be applied with a syringe (not shown), before being sucked out through the air exhaust.
