Coding of Visual, Auditory, Rule, and Response Information in the Brain: 10 Years of Multivoxel Pattern Analysis

Alexandra Woolgar, Jade Jackson, John Duncan
2016 Journal of Cognitive Neuroscience  
Visual, auditory, and motor networks predominantly (but not exclusively) coded visual, auditory, and motor information, respectively.  ...  By contrast, the frontoparietal multiple-demand network was characterized by domain generality, coding visual, auditory, motor, and rule information.  ...  Analyses Our first analysis quantified the prevalence of visual, auditory, rule, and motor information coding in different brain networks.  ...

Adaptive Coding of Task-Relevant Information in Human Frontoparietal Cortex

A. Woolgar, A. Hampshire, R. Thompson, J. Duncan
2011 Journal of Neuroscience  
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.  ...

Integrated Intelligence from Distributed Brain Activity

John Duncan, Moataz Assem, Sneha Shashidhara
2020 Trends in Cognitive Sciences  
Recent analyses of fluid intelligence suggest a core process of cognitive focus and integration, organizing the components of a cognitive operation into the required computational structure.  ...  Though still only in broad outline, these data suggest how distributed brain activity can build complex, organized cognition.  ...  In human brain imaging, multivoxel pattern analysis confirms widespread MD encoding of different aspects of a current task, including discrimination of relevant stimuli, rules, responses, and more [59  ...
