  • visuospatial Attention Disturbance in duchenne muscular dystrophy
    Developmental Medicine & Child Neurology, 2010
    Co-Authors: Maria Clara Drummond Soares De Moura, Luiz Eduardo Ribeiro Do Valle, Maria Bernadete Dutra Resende, Umbertina Conti Reed, Katia Osternack Pinto
    Abstract:

    Aim  The cognitive deficits present in the Duchenne muscular dystrophy (DMD) are not yet well characterized. Attention, considered to be the brain mechanism responsible for the selection of sensory stimuli, could be disturbed in DMD, contributing, at least partially, to the observed global cognitive deficit. The aim of this study was to investigate Attentional function in individuals with DMD. Method  Twenty-five males (mean age 12y; SD 2y 2mo) with DMD and 25 healthy males (mean age 12y; SD 2y) were tested in a visuospatial task (Posner computerized test). They were instructed to respond as quickly as possible to a lateralized visual target stimulus with the ipsilateral hand. Their Attention was automatically orientated by a peripheral prime stimulus or, alternatively, voluntarily orientated by a central spatially informative cue. Results  The main result obtained was that the Attentional effect (sum of the benefit and the cost of Attention) did not differ between the two groups in the case of automatic Attention (p=0.846) but was much larger for individuals with DMD than for comparison individuals in the case of voluntary Attention (p<0.001). Interpretation  The large voluntary Attentional effect exhibited by the participants with DMD seems similar to that of younger children, suggesting that the disease is associated with delayed maturation of voluntary Attention mechanisms.

  • Landscape ecology: what is the state of the science?
    Annual Review of Ecology Evolution and Systematics, 2005
    Co-Authors: Monica G. Turner
    Abstract:

    ▪ Abstract Landscape ecology focuses on the reciprocal interactions between spatial pattern and ecological processes, and it is well integrated with ecology. The field has grown rapidly over the past 15 years. The persistent influence of land-use history and natural Disturbance on contemporary ecosystems has become apparent. Development of pattern metrics has largely stabilized, and they are widely used to relate landscape pattern to ecological responses. Analyses conducted at multiple scales have demonstrated the importance of landscape pattern for many taxa, and spatially mediated interspecific interactions are receiving increased Attention. Disturbance remains prominent in landscape studies, and current research is addressing Disturbance interactions. Integration of ecosystem and landscape ecology remains challenging but should enhance understanding of landscape function. Landscape ecology should continue to refine knowledge of when spatial heterogeneity is fundamentally important, rigorously test the ...
