Together, this research indicates that we represent observed actions through motor simulation in shared neural circuits (Keysers and Gazzola 2006) .  ...  The intersection of these two activation maps was used to localize sVx activation, which served as a proxy for the human mirror neuron system (Gazzola and Keysers 2009 ).  ...

Measuring shared responses across subjects using intersubject correlation [article]

Samuel A. Nastase, Valeria Gazzola, Uri Hasson, Christian Keysers
2019 bioRxiv   pre-print
Our capacity to jointly represent information about the world underpins our social experience. By leveraging one individual's brain activity to model another's, we can measure shared information across brains—even in dynamic, naturalistic scenarios where an explicit response model may be unobtainable. Introducing experimental manipulations allows us to measure, for example, shared responses between speakers and listeners, or between perception and recall. In this tutorial, we develop the logic

We also extend this logic to spatially distributed response patterns and functional network estimation. We provide a thorough and accessible treatment of methodological considerations specific to ISC analysis, and outline best practices.

Social Neuroscience: Mirror Neurons Recorded in Humans

Christian Keysers, Valeria Gazzola
2010 Current Biology  
New single-cell recordings show that humans do have mirror neurons, and in more brain regions than previously suspected. Some action-execution neurons were seen to be inhibited during observation, possibly preventing imitation and helping self/other discrimination.

Significance tests for Leave-One-Out Inter-Subject Correlations in fMRI [article]

Lorenzo De Angelis, Valeria Gazzola, Christian Keysers
2020 bioRxiv   pre-print
The inter-subject correlation of fMRI data of different subjects performing the same fMRI task (ISC) is in principle a powerful way to localize and differentiate neural processes caused by a presented stimulus from those that spontaneously or idiosyncratically take place in each subject. The wider adoption of this method has however been impeded by the lack of widely available tools to assess the significance of the observed correlations. Several non-parametric approaches have been proposed,
more » ... these approaches are computationally intensive, challenging to implement, and sensitive methods to correct for multiple comparison across voxels in these approaches are not yet well established. More widely available, and computationally simple, parametric methods have been criticized on the basis that dependencies in the data could inflate false positives. Here, using three independent resting state fMRI datasets, we demonstrate that conventional parametric tests actually do provide appropriate control for false positives for inter-subject correlation analyses. This finding paves the way to a wider adoption of ISC, and empowers a wider range of neuroimagers to use ISC to tackle the challenges of naturalistic neuroscience.

Classification of Medical Images Using Non-linear Distortion Models [chapter]

Daniel Keysers, Christian Gollan, Hermann Ney
2004 Informatik aktuell  
We propose the application of two-dimensional distortion models for comparisons of medical images in a distance-based classifier. We extend a simple zero-order distortion model by using local context within the compared image parts. Vertical and horizontal image gradients as well as small sub images are used as local context. Taking into account dependencies within the displacement field of the distortion by using a pseudo two-dimensional hidden Markov model with additional distortion
