Configural processing enables discrimination and categorization of face-like stimuli in honeybees
A Avargues-Weber, G Portelli… - Journal of …, 2010 - journals.biologists.com
We studied whether honeybees can distinguish face-like configurations by using standardized
stimuli commonly employed in primate and human visual research. Furthermore, we …

Honeybees change their height to restore their optic flow
To further elucidate the mechanisms underlying insects’ height and speed control, we trained
outdoor honeybees to fly along a high-roofed tunnel, part of which was equipped with a …

[HTML][HTML] Honeybees' speed depends on dorsal as well as lateral, ventral and frontal optic flows
Flying insects use the optic flow to navigate safely in unfamiliar environments, especially by
adjusting their speed and their clearance from surrounding objects. It has not yet been …

Rank order coding: a retinal information decoding strategy revealed by large-scale multielectrode array retinal recordings
How a population of retinal ganglion cells (RGCs) encodes the visual scene remains an open
question. Going beyond individual RGC coding strategies, results in salamander suggest …

Linguistic intergroup bias and implicit attributions
This experiment addresses the relation between the ‘Linguistic intergroup bias’ (that is, the
tendency to describe positive in‐group and negative out‐group behaviours in more abstract …

[HTML][HTML] PRANAS: a new platform for retinal analysis and simulation
The retina encodes visual scenes by trains of action potentials that are sent to the brain via
the optic nerve. In this paper, we describe a new free access user-end software allowing to …
