Over the past decade, researchers have increasingly utilized powerful analytical tools (e.g., multivoxel pattern analysis) to decode the information represented within distributed functional magnetic resonance ...
We emphasize that, in addition to characterizing the contents of memories, analyses of distributed patterns shed light on the processes that influence how information is encoded, maintained, or retrieved ...
ANALYSIS Multivoxel pattern analysis (MVPA) typically begins with the division of each participant's fMRI data into training and test patterns, where "patterns" refer to brain activity measures extracted ...

Using multivoxel pattern analysis of human functional imaging data, we demonstrate an adaptive change in the patterns of activation coding task-relevant stimulus distinctions. ...
Visual cortices showed the opposite result: a weaker representation of perceptual information in line with the physical change in the stimulus. ...
For low minus high, there was increased position coding in the visual cortices (peak: 10, Ϫ82, 10, BA 17), as seen in the ROI analysis, and no differences in rule or response coding. ...

To probe the neural basis for representations of trained words, searchlight multivoxel pattern analysis (MVPA) revealed that a subset of dogs had clusters of informative voxels that discriminated between ...
These results demonstrate that dogs' processing of human words utilizes basic processes like novelty detection, and for some dogs, may also include auditory and hedonic representations. ...
As an exploratory analysis, we used searchlight Multivoxel Pattern Analysis (MVPA) to identify regions potentially involved in the representation of words that were not captured in the univariate analysis ...
