Mammal responses to human footprint vary with spatial extent but not with spatial grain

Spatial responses to predators vary with prey escape mode

Objects with Fuzzy Spatial Extent

Abstmct The determination of the spatia) extent of geo-obiects is generally approached through their boundaries or, more precisely, thrcugh the positions of their boundary points. The analysis of the geometric uncertainty of the objects is therefore often based on accuracy models for the coordinates of these points. In many survey disciplines objects are mapped, however, that are not crisp wel)...

Inflammatory nociception responses do not vary with age, but diminish with the pain history

Some of the relevant factors that must be considered when dealing with old age include its growing numbers in the general population and pain contention in this age group. In this sense, it is important to study whether antinociceptive responses change with age. To elucidate this point, persistent pain in animals is the preferred model. In addition, the response to inflammatory pain in the same...

BOLD human responses to chromatic spatial features.

Animal physiological and human psychophysical studies suggest that an early step in visual processing involves the detection and identification of features such as lines and edges, by neural mechanisms with even- and odd-symmetric receptive fields. Functional imaging studies also demonstrate mechanisms with even- and odd-receptive fields in early visual areas, in response to luminance-modulated...

Pupillary responses during lexical decisions vary with word frequency but not emotional valence.

Pupillary responses were examined during a lexical decision task (LDT). Word frequency (high and low frequency words) and emotional valence (positive, neutral and negative words) were varied as experimental factors incidental to the subjects. Both variables significantly affected lexical decision performance and an interaction effect was observed. The behavioral results suggest that manipulatin...
