Perhaps more importantly, Krechevsky's interpretation of the impact of task complexity on the emergence of gestalt percepts anticipated the conclusions reached by the most recent studies of rat object recognition about the crucial role of task demands/constraints in determining the complexity of rat recognition strategy [118,120].
While the former approach was applied in the most recent studies of rat invariant recognition [118 120], the latter was followed by Simpson and Gaffan in their very thorough investigation of visual scene and object processing in rats [147].
Among the four peer-reviewed studies of the compounds by a group of French and German scientists that were considered by European officials, the most recent looked at rats that were injected with a substance that produces colon cancer.
Crops destroyed Having devoured much of the bamboo flowers and fruit in the Chittagong Hill Tracts, the most recent plague of rats began eating their way through paddy and vegetable crops late last year.
Three of the four species of Crateromys were first described by scientists during the 1980s and '90s, the most recent being the Panay Island cloud rat (C. heaneyi) in 1996.
These 30-mers were compared to the most recent (November 2004) assembly of the rat genome using the BLAST-like alignment tool (BLAT) available from the UCSC website [ 20].
The ancestral Murinae branch defines the most recent common ancestor of mouse and rat.
The ancestral Muridae branch marks the most recent common ancestor of modern mouse, rat and guinea pig species and is depicted in Figure 1.
This result was confirmed with synthetic peptides, and the most recent study demonstrated that pups born from rats immunized with the Ro52 peptide 200 239 developed atrioventricular block [ 24].
