Computation of Object Approach by a Wide-Field, Motion-Sensitive Neuron
TLDR
The lobula giant motion detector in the locust visual system is a wide-field, motion-sensitive neuron that responds vigorously to objects approaching the animal on a collision course and might be an ideal model to investigate the biophysical implementation of a multiplication operation by single neurons.
Dendritic structure and receptive-field organization of optic flow processing interneurons in the fly.
TLDR
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.
Multiplicative computation in a visual neuron sensitive to looming
TLDR
It is shown that postsynaptic inhibition has a predominant role, suggesting that multiplication is implemented within the neuron itself, consistent with an implementation of multiplication based on dendritic subtraction of two converging inputs encoded logarithmically, followed by exponentiation through active membrane conductances.
Estimation of self-motion by optic flow processing in single visual interneurons
TLDR
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.
Binocular contributions to optic flow processing in the fly visual system.
TLDR
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.
Nonlinear Integration of Visual and Haltere Inputs in Fly Neck Motor Neurons
TLDR
This work studies how fly neck motor neurons integrate information from two well characterized sensory systems: visual information from the compound eye and gyroscopicInformation from the mechanosensory halteres to produce nonlinear gating-like behavior.
Plasticity in the visual system is correlated with a change in lifestyle of solitarious and gregarious locusts.
TLDR
This work analyzed in both phases the responses of an identified visual interneuron, the descending contralateral movement detector (DCMD), which responds to approaching objects, and demonstrated that habituation of DCMD is fivefold stronger in solitarious locusts.
Visuomotor Transformation in the Fly Gaze Stabilization System
TLDR
The results suggest that—like the tangential cells—NMNs are tuned to panoramic retinal image shifts, or optic flow fields, which occur when the fly rotates about particular body axes, which results in the NMNs being more selective for rotation than the LPTCs.
