Widespread sensitivity to looming stimuli and small moving objects in the central complex of an insect brain.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
In many situations animals are confronted with approaching objects. Depending on whether the approach represents a potential threat or is intended during a goal-oriented approach, the adequate behavioral strategies differ. In all of these cases the visual system experiences an expanding or looming shape. The neuronal machinery mediating looming elicited behavioral responses has been studied most comprehensively in insects but is still far from being fully understood. It is particularly unknown how insects adjust their behavior to objects approaching from different directions. A brain structure that is thought to play an important role in spatial orientation in insects is the central complex (CC). We investigated whether CC neurons process information about approaching objects on a collision course. We recorded intracellularly from CC neurons in the locust Schistocerca gregaria during visual stimulation via lateral LCD screens. Many neurons in the locust CC, including columnar and tangential neurons, were sensitive to looming stimuli. Some of the neurons also responded to small moving targets. Several cell types showed binocular responses to looming objects, and some neurons were excited or inhibited depending on which eye was stimulated. These neurons may, therefore, detect the gross azimuthal direction of approaching objects and may mediate directional components of escape or steering movements.
