Abstract Honey bees exhibit remarkable visual learning capacities, which can be studied using virtual reality (VR) landscapes in laboratory conditions. Existing VR environments for are imperfect as they provide either open-loop conditions or 2D displays. Here we achieved a true 3D environment walking learned to discriminate rewarded from punished stimulus based on color differences. We included ventral frontal background cues, were also subjected updating the bee movements. thus if and how...
Social behavior of honeybees (Apis mellifera) has been extensively investigated, but little is known about its neuronal correlates. We developed a method that allowed us to record extracellularly from mushroom body extrinsic neurons (MB ENs) in freely moving bee within small functioning mini colony approximately 1000 bees. The aim this study was correlate activity multimodal high-order MB ENs with social close natural setting. all bees the video recorded. recorded animal compared other hive...
Navigating animals combine multiple perceptual faculties, learn during exploration, retrieve multi-facetted memory contents, and exhibit goal-directedness as an expression of their current needs motivations. Navigation in insects has been linked to a variety underlying strategies such path integration, view familiarity, visual beaconing, goal-directed orientation with respect previously learned ground structures. Most works, however, study navigation either from field perspective, analyzing...
Central place foraging insects like honeybees and bumblebees learn to navigate efficiently between nest feeding site. Essential components of this behavior can be moved the laboratory. A major component navigational learning is active exploration test arena. These conditions have been used here search for neural correlates exploratory walking in central arena (ground), thigmotactic periphery (slope). We chose mushroom body extrinsic neurons (MBENs) because their learning-related plasticity...
Recent developments allowed establishing virtual-reality (VR) setups to study multiple aspects of visual learning in honey bees under controlled experimental conditions. Here, we adopted a VR environment investigate the buff-tailed bumble bee Bombus terrestris. Based on responses appetitive and aversive reinforcements used for conditioning, show that had proper motivation engage experiments they learned efficiently elemental color discriminations. In doing so, reduced latency make choice,...
As a canary in coalmine warns of dwindling breathable air, the honeybee can indicate health an ecosystem. Honeybees are most important pollinators fruit-bearing flowers, and share similar ecological niches with many other pollinators; therefore, colony reflect conditions whole The may be mirrored social signals that bees exchange during their sophisticated body movements such as waggle dance. To observe these changes, we developed automatic system records quantifies under normal beekeeping...
Color vision in honeybees is a well-documented perceptual phenomenon including multiple behavioral tests of trichromaticity and color opponency. Data on the combined color/space properties high order visual neurons bee brain however limited. Here we fill this gap by analyzing activity anterior optic tract (AOT), region suggested to be involved chromatic processing. The spectral response 72 units were measured using UV, blue green light stimuli presented 266 positions field. majority these...
The promise of open hardware as a branch science is sustainable change research instrumentation towards more openly documented and licensed designs. Methods, code, data are already valued by journal editors peer-reviews to judge if study's result can be replicated with the information provided in manuscript. movement seeks include laboratory tools into same category. Availability access equipment set democratize professional lab work field studies well enhance transferability methods civic...
This paper aims to describe the need for a course that teaches open source principles, 3D printing, and programming researchers in Africa. It also describes implementation of detail so others may conduct similar programs. The primary goal “Open Labware: Printing Your Own Lab Equipment” workshop organised by TReND Africa (Teaching Research Natural Sciences Development Africa) is help development local expertise capabilities teaching faculty area Open Labware, capacitating participants create...
