ABSTRACT
Electrophysiological recordings from single cells support the neuroanatomical data. The majority of these cells respond to more than one modality. Therefore, an electrophysiological analysis of central neurons in the bee brain can only be successful when it examines first the general response properties of single neurons and then, in a second step, tests stimulus combinations which are relevant for behavior. Neurons of the antenno-glomerular-tract were analysed and identified with electrophysiological techniques by O. Homberg. The neuroanatomical and electrophysiological results concerning the input of the mushroom bodies are in good agreement. Bees show various behavioral responses in the laboratory situation; many of these reactions have the properties of reflexes. Two behavioral modifications were analysed on the neuronal level: sensitization of the antennal reflex and associative olfactory learning. The changes on the neuronal level compare directly with the changes observed in behavior.
