Central mitotic spindles in Diatoma vulgare have been investigated using serial sections and electron microscopy. Spindles at both early stages (before metaphase) and later stages of mitosis (metaphase to telophase) have been analyzed. We have used computer graphics technology to facilitate the analysis and to produce stereo images of the central spindle(More)
OBJECTIVES To determine if the activity-dependent trafficking of γ2 subunit-containing γ-aminobutyric acid type A receptors (GABAA Rs) that has been observed in older animals and posited to contribute to benzodiazepine pharmacoresistance during status epilepticus (SE) is age-dependent, and to evaluate whether blockade of protein phosphatases can inhibit or(More)
BACKGROUND The Slitrk family of leucine-rich repeat (LRR) transmembrane proteins bears structural similarity to the Slits and the Trk receptor families, which exert well-established roles in directing nervous system development. Slitrks are less well understood, although they are highly expressed in the developing vertebrate nervous system. Moreover, slitrk(More)
In a series of six experiments deaf and hearing adolescents were compared on attainment of formal operations in Piaget's theory as represented by performance on probability problems. Performance of deaf subjects provided a desirable control comparison, since their knowledge of probability concepts was most likely acquired outside school classrooms. The(More)
Six-, 8-, 10-, and 12-year-old children (10 boys and 10 girls) reconstructed two visual patterns from immediate memory, while other 5- and 6-year-old children (10 boys and 10 girls) reconstructed the identical patterns by direct copying. Patterns were simple and composed entirely of circles or squares as component items. Four results were emphasized: (a)(More)
It was hypothesized that both aggression and incongruity are variables that will positively influence preschool children's judgments of humorous incidents. Past research has shown the influence of incongruity on humor only for school-age children, and--with the exception of studies of children's television viewing--the allegedly "antisocial" variable of(More)
