Organizing dimensions in naturalistic action perception
[link], paper in prep.
We use a data-driven method to recover interpretable dimensions from behavioural action similarity judgments across two different experiments.
Action representations in brain and behaviour
We evaluate the contribution of visual, social, and action features to behavioural and neural (EEG) naturalistic action representations.
MEG hypoconnectivity linked to rare copy number variants
We find decreased MEG resting-state connectivity in adults with rare high-risk copy number variants (CNVs), suggesting a potential common mechanism across genotypes.
Feature extraction in rapid face perception
Using cross-identity decoding, RSA, and variance partitioning, we find a link between facial configuration, ventral stream MEG patterns, and behavioural responses during an expression discrimination task.
Scene representations, from features to categories
Cross-decoding and source-space RSA show that a categorical response to scenes emerges in visual cortex within 200 ms, potentially supported by low spatial frequency features, even in the absence of a categorization task.
Spatiotemporal dynamics of expression processing
Sensor and source-space MVPA of whole-brain MEG data shows that the extraction of expression-related features from faces begins within 100 ms in visual cortex in the absence of an expression-related task.
