Abstract
Neurones in the optic ganglia of free-moving and fixed CalHphora wereelectrically stimulated with extracellular microelectrodes. The maximumdiameter of the stimulating focus was 20 /im in the antero-posterior axis.Course control and landing manoeuvres could be elicited by stimulating inthe lobula plate but not in the lobula or medulla. With stimulation in thevicinity of the H neurones, yaw responses were evoked. Direction of theresponse was dependent on stimulation polarity. This supports thehypothesis that H neurones mediate optomotor responses. Stimulation inthe posterior part of the lobula plate, close to the V neurones, elicited pitch, lift and thrust responses as well as landing reactions.
