Action Intention Modulates the Activity Pattern in Early Visual Areas
The activity pattern in the early visual cortex (EVC) can be used to predict upcoming actions as it is functionally connected to higher-order motor areas. However, the mechanism by which the EVC enhances action-relevant features is unclear. We explored this using fMRI. Participants performed Align …

The influence of semantics on the visual processing of natural scenes
… Does semantics modulate visual processing. Using multi-voxel pattern analysis (MVPA) and fMRI decoding we examined the similarity of neural activity across pictures and words that describe natural scenes. A whole brain MVPA searchlight revealed multiple brain regions in the occipitotemporal, …

The Role of the DLPFC in Bilingual and Monolingual Switching: Evidence from MVPA and tDCS
… in this relationship. The first study used multi-voxel pattern analysis (MVPA) to determine whether the patterns of fMRI activity in the left and right DLPFC for language control were similar to the patterns of activity for non-linguistic control. In this study, the left DLPFC showed …

Univariate and Multivariate fMRI Investigations of Delay Discounting and Episodic Future Thinking in Alcohol Use Disorder
… been directly studied. To examine this, we used multi-voxel pattern analysis (MVPA) methods such as multivariate classification using Support Vector Machine (SVM) algorithms and trained accurate classifiers of high vs. low impulsivity with individual fMRI brain maps. Our results demonstrate that …

Neural Processes Underlying the Intrusion of Unwanted Memories
… of attention to invalidly cued items. Using multi-voxel pattern analysis (MVPA), I found a significant similarity in the activation patterns caused by mnemonic intrusions and visual reorienting. As such, an intruding memory may capture attention just like a goal-relevant visual stimulus does, …

Improving Data Quality for High Resolution Functional MRI in Cognitive Neuroscience Applications
… difference between the two methods, more complex analysis such as the Linear Discriminant Contrast (LDC) showed that the PMC data was indeed cleaner than the RMC data for higher resolution data. Next, I compared the sensitivity of two multi-voxel pattern analysis (MVPA) methods, Support Vector …
