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

Many animals begin to escape by moving away from a threat the instant it is detected.
However, the escape jumps of locusts take several hundred milliseconds to produce and the …

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) …

Flying locusts perform a characteristic gliding dive in response to predator-sized stimuli
looming from one side. These visual looming stimuli trigger trains of spikes in the …

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 …

ABSTRACT A Silicon Graphics computer was used to challenge the locust d escending c
ontralateral m ovement d etector (DCMD) neurone with images of approaching objects. The …

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

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

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

We recorded the activity of the right and left descending contralateral movement detectors
responding to 10-cm (small) or 20-cm (large) computer-generated spheres approaching …
