Anatomical physiology of spatial extinction.
Neurologically intact volunteers participated in a functional magnetic resonance imaging experiment that simulated the unilateral (focal) and bilateral (global) stimulations used to elicit extinction in patients with hemispatial neglect. In peristriate areas, attentional modulations were selectively sensitive to contralaterally directed attention. A higher level of mapping was observed in the i...
متن کاملExtinction and the spatial dynamics of biodiversity
The fossil record amply shows that the spatial fabric of extinction has profoundly shaped the biosphere; this spatial dimension provides a powerful context for integration of paleontological and neontological approaches. Mass extinctions evidently alter extinction selectivity, with many factors losing effectiveness except for a positive relation between survivorship and geographic range at the ...
متن کاملExtinction rates of established spatial populations.
This paper deals with extinction of an isolated population caused by intrinsic noise. We model the population dynamics in a "refuge" as a Markov process which involves births and deaths on discrete lattice sites and random migrations between neighboring sites. In extinction scenario I, the zero population size is a repelling fixed point of the on-site deterministic dynamics. In extinction scena...
متن کاملThe challenges of representing anatomical spatial relations.
Puget, Mejino, Detwiler, Franklin and Brinkley introduce their article “Spatialsymbolic Query Engine in Anatomy” [1] by posing a seemingly straightforward anatomy question: “what vital organs would potentially be impacted by a bullet wound to the abdomen?” More than 50 years ago, such a question may well have been included at the end of a yearlong anatomy course in an essay exam. Such an openen...
متن کاملSpatial and temporal influences on extinction.
This study investigated the spatial and temporal characteristics of the attentional deficit in patients exhibiting extinction to determine the extent to which these characteristics can be explained by a theory of an underlying gradient resulting from the differential contribution of interacting cell populations. The paradigm required the identification of two letters whose spatial location was ...
