Discrimination of features in natural scenes by a dragonfly neuron

SD Wiederman, DC O'Carroll - Journal of Neuroscience, 2011 - Soc Neuroscience
Flying insects engage in spectacular high-speed pursuit of targets, requiring visual
discrimination of moving objects against cluttered backgrounds. As a first step toward …

Spatial facilitation by a high-performance dragonfly target-detecting neuron

K Nordström, DM Bolzon, DC O'Carroll - Biology letters, 2011 - royalsocietypublishing.org
Many animals visualize and track small moving targets at long distances—be they prey,
approaching predators or conspecifics. Insects are an excellent model system for …

Dragonfly neurons selectively attend to targets within natural scenes

BJE Evans, DC O'Carroll, JM Fabian… - Frontiers in Cellular …, 2022 - frontiersin.org
Aerial predators, such as the dragonfly, determine the position and movement of their prey
even when both are moving through complex, natural scenes. This task is likely supported …

A model for the detection of moving targets in visual clutter inspired by insect physiology

SD Wiederman, PA Shoemaker, DC O'Carroll - PloS one, 2008 - journals.plos.org
