Planning is an important component of cognition that contributes, for example, to efficient movement through space. In the current study we presented novel two-dimensional alley mazes to four chimpanzees and three capuchin monkeys to identify the nature and efficiency of planning in relation to varying task parameters. All the subjects solved more mazes(More)
MOTIVATION Data on protein-protein interactions (PPIs) are increasing exponentially. To date, large-scale protein interaction networks are available for human and most model species. The arising challenge is to organize these networks into models of cellular machinery. As in other biological domains, a comparative approach provides a powerful basis for(More)
The authors investigated strategies used to combine seriated cups by apes (Pan troglodytes and P. paniscus) and monkeys (Cebus apella) using a protocol reported in P. M. Greenfield, K. Nelson, and E. Saltzman's (1972) study with children. It was hypothesized that apes would exhibit more hierarchical combinations of cups than monkeys, given apes' language(More)
The pathogenesis of myocardial necrosis produced in the albino rat by a single large dose of the potent alpha and beta adrenergic agonist epinephrine was investigated. In confirmation and extension of earlier observations with the alpha adrenergic antagonist tolazoline, it was found that alpha adrenergic blockade with phenoxybenzamine or beta adrenergic(More)
1 3.1 Low level analysis of microarrays 3.1.1 Introduction This course deals with High level analysis of data gathered by microarrays. Different types of High level analysis include: • (Bi-)Clustering • Reconstruction of transcriptional networks • Induction of classification rules All of these high level analysis methods are based on the same raw data-A(More)
As we studied in our first lecture, each cell contains a copy of the whole gene. But we have many tissues that are constructed of different cells, that are responsible for various tasks. Thus, each cell utilizes only a subset of its genes. Most genes are highly regulated their expression is limited to specific tissues, developmental stages, physiological(More)
