Visually guided collision avoidance is critical for the survival of many animals. The execution
of successful collision-avoidance behaviors requires accurate processing of approaching …

1. In response to a rapidly approaching object, intracellular recordings show that excitation
in the locust lobula giant movement detecting (LGMD) neuron builds up exponentially …

Locusts have two large collision-detecting neurons, the descending contralateral movement
detectors (DCMDs) that signal object approach and trigger evasive glides during flight. We …

The firing patterns of visual neurons tracking approaching objects need to be translated into
appropriate motor activation sequences to generate escape behaviors. Locusts possess an …

1. We describe a four-layered neural network (Fig. 1), based on the input organization of a
collision signaling neuron in the visual system of the locust, the lobula giant movement …

Locusts possess an identified neuron, the descending contralateral movement detector
(DCMD), conveying visual information about impending collision from the brain to thoracic …

Neurons in the locust visual system encode approaches of looming stimuli and are
implicated in production of escape behaviours. The lobula giant movement detector (LGMD) …

Many animals must contend with visual cues that provide information about the
spatiotemporal dynamics of multiple objects in their environment. Much research has been …

How higher-order sensory neurons generate complex selectivity from their simpler inputs is
a fundamental question in neuroscience. The lobula giant movement detector (LGMD) is …

The lobula giant movement detector (LGMD) of locusts is a visual interneuron that responds
with an increasing spike frequency to an object approaching on a direct collision course …
