Computation of Object Approach by a Wide-Field, Motion-Sensitive Neuron
The lobula giant motion detector (LGMD) in the locust visual system is a wide-field, motion-sensitive neuron that responds vigorously to objects approaching the animal on a collision course. WeExpand

Dendritic structure and receptive-field organization of optic flow processing interneurons in the fly.
The third visual neuropil (lobula plate) of the blowfly Calliphora erythrocephala is a center for processing motion information. Expand

Multiplicative computation in a visual neuron sensitive to looming
Multiplicative operations are important in sensory processing, but their biophysical implementation remains largely unknown. We investigated an identified neuron (the lobula giant movement detector,Expand

Estimation of self-motion by optic flow processing in single visual interneurons
We recorded intracellularly from identified interneurons in the third visual neuropile of the blowfly. Expand

Sensory Systems and Flight Stability: What do Insects Measure and Why?
Abstract In the absence of much passive stability, flying insects rely upon active stabilisation, necessitating the provision of rich sensory feedback across a range of modalities. Here we considerExpand

Binocular contributions to optic flow processing in the fly visual system.
Integrating binocular motion information tunes wide-field direction-selective neurons in the fly optic lobe to respond preferentially to specific optic flow fields. This is shown by measuring theExpand

Nonlinear Integration of Visual and Haltere Inputs in Fly Neck Motor Neurons
We study how fly neck motor neurons integrate information from two well characterized sensory systems: visual information from the compound eye and gyroscopic information from mechanosensory halteres. Expand

Visuomotor Transformation in the Fly Gaze Stabilization System
For sensory signals to control an animal's behavior, they must first be transformed into a format appropriate for use by its motor systems. This fundamental problem is faced by all animals, includingExpand

Plasticity in the visual system is correlated with a change in lifestyle of solitarious and gregarious locusts.
We demonstrate pronounced differences in the visual system of a polyphenic locust species that can change reversibly between two forms (phases), which vary in morphology and behavior. At lowExpand

Multiplication and stimulus invariance in a looming-sensitive neuron
Multiplicative operations and invariance of neuronal responses in vivo, either at the single cell or at the network level, remain to a large extent unknown. Expand
