Real-time experiment-Visualisation of spontaneous background activity. Spontaneous background activity of glomeruli in the honeybee AL, visualised by low-rank approximation. Top: Fluorescence images recorded at 5 Hz. Each image is the ratio of consecutive images recorded with 340 nm and with 380 nm excitation light (see Methods). Bottom: The same images after processing with the real-time software.
