Dendritic structure and receptive-field organization of optic flow processing interneurons in the fly.
Theoretical considerations and quantitative analyses of the data show that VS neurons are highly specialized neural filters for optic flow processing and thus for the visual sensation of self-motions in the fly. Expand
The halteres of the blowfly Calliphora
We quantitatively analysed compensatory head reactions of flies to imposed body rotations in yaw, pitch and roll and characterized the haltere as a sense organ for maintaining equilibrium. DuringExpand
Estimation of self-motion by optic flow processing in single visual interneurons
This study shows how complex visual discrimination can be achieved by task-oriented preprocessing in single neurons by recording intracellularly from identified interneurons in the third visual neuropile of the blowfly. Expand
Binocular contributions to optic flow processing in the fly visual system.
The distributions of LPDs within the binocular response fields of each neuron show marked similarities to the optic flow fields created by particular types of self-movements of the fly. Expand
Gaze control in the blowfly Calliphora: a multisensory, two-stage integration process
Flies use several visual and mechanosensory cues to keep flight balance and to stabilize their eyes relative to the surroundings by compensatory head/eye movements. Expand
Common visual response properties of giant vertical cells in the lobula plate of the blowflyCalliphora
These results confirm earlier findings that giant vertical cells have many response properties in common, and are best suited to perceive widefield motion, which occurs when a fly performs rotatory and translatory movements in a resting environment. Expand
Optical properties of the ocelli of Calliphora erythrocephala and their role in the dorsal light response
The results show that, in Calliphora, the ocelli have little influence on head orientation during flight, and must be assumed to serve other functions. Expand
Mechanosensory control of compensatory head roll during flight in the blowflyCalliphora erythrocephala Meig.
Summary1.In the blowflyCalliphora flying stationarily in a wind tunnel, compensatory head movements were elicited by rolling the fly about its longitudinal axis (Fig. 1). Responses were recorded onExpand
Spike responses of ‘non-spiking’ visual interneurone
It is shown that at least eight individually identifiable movement-sensitive cells, which have the characteristic properties of non-spiking interneurones, will generate spikes with imposed hyperpolarisation in the fly visual nervous system. Expand
Compensatory head roll in the blowfly Calliphora during flight
Video records were made of the blowfly Calliphora erythrocephala L. mainly during tethered flight in a wind-tunnel, to study its movements about the longitudinal body axis (roll). During undisturbedExpand
