Electrophysiological studies on the insect compound eye

Using electrophysiological studies of the insect compound eye as an example, this paper describes how to set-up the experimental equipment, how to prepare and use recording electrodes, how to make a preparation, and how to locate the electrode in the tissue after the recording. The basic anatomy of the compound eye is explained and functional parameters such as absolute sensitivity versus activity, colour and polarisation sensitivity, flicker fusion frequency, and information transfer are mentioned.
