Bumblebees Learn Polarization Patterns
Foraging insect pollinators such as bees must find and identify flowers in a complex visual environment. Bees use skylight polarization patterns for navigation, a capacity mediated by the polarization-sensitive dorsal rim area (DRA) of their eye. While other insects use polarization sensitivity to identify appropriate habitats, oviposition sites, and food sources, to date no nonnavigational fun...
متن کاملThe binding of visual patterns in bumblebees
Bees navigating between their nests and foraging sites rely on their ability to learn and to recall many complex visual patterns [1-4]. How are the elements that make up one of these patterns bound together so that the whole pattern can be recalled when it is required? Consider the sentence: 'Dons nod off.' The words in it can be distinguished by the pattern of elements or letters that they con...
متن کاملPolarization patterns in Kerr Media
We study spatiotemporal pattern formation associated with the polarization degree of freedom of the electric eld amplitude in a mean eld model describing a Kerr medium in a cavity with at mirrors and driven by a coherent plane-wave eld. We consider linearly as well as elliptically polarized driving eld and situations of self-focusing and self-defocusing. For the case of self-defocusing and line...
متن کاملNeuronal Polarization: Old Cells Can Learn New Tricks
Regeneration was once thought to be exclusive to young neurons. Now, a new study shows that functional and interconnected hippocampal neurons have the potential to quickly recover from losing an axon. They do so by signaling a dendrite to change its specification and replace the missing axon by rearranging the microtubule cytoskeleton.
متن کاملSocial Learning in Bumblebees (Bombus impatiens): Worker Bumblebees Learn to Manipulate and Forage at Artificial Flowers by Observation and Communication within the Colony
Social learning occurs when one individual learns from another, mainly conspecific, often by observation, imitation, or communication.Using artificial flowers, we studied social learning by allowing test bumblebees to (a) see dead bumblebees arranged in foraging positions or (b) watch live bumblebees actually foraging or (c) communicate with nestmates within their colony without having seen for...
