The pigeon as particle filter
Although theorists have interpreted classical conditioning as a laboratory model of Bayesian belief updating, a recent reanalysis showed that the key features that theoretical models capture about learning are artifacts of averaging over subjects. Rather than learning smoothly to asymptote (reflecting, according to Bayesian models, the gradual tradeoff from prior to posterior as data accumulate...

متن کاملFlies as models of disease
By all appearances flies and humans are quite different. Nevertheless, their genetics and underlying DNA sequences are remarkably similar. Many human disease genes have sequences common with those in Drosophila (Bier, 2005). This genetic similarity supports the notion that basic research in Drosophila will accelerate translational research for a wide range of diseases. Disease-orientated Drosop...
متن کاملBacterial endosymbiont of the slender pigeon louse, Columbicola columbae, allied to endosymbionts of grain weevils and tsetse flies.
The current study focuses on a symbiotic bacterium found in the slender pigeon louse, Columbicola columbae (Insecta: Phthiraptera). Molecular phylogenetic analyses indicated that the symbiont belongs to the gamma subdivision of the class Proteobacteria and is allied to Sodalis glossinidius, the secondary symbiont of tsetse flies (Glossina spp.) and also to the primary symbiont of grain weevils ...
