Differential Involvement of Somatosensory and Interoceptive Cortices during the Observation of Affective Touch
■ Previous studies suggested that the observation of other individualsʼ somatosensory experiences also activates brain circuits processing oneʼs own somatosensory experiences....

Data-driven fMRI group classification using connected components and Gaussian process classifiers
Functional magnetic resonance imaging (fMRI) is a popular tool for studying brain activity due to its non-invasiveness. Conventionally an expected response needs to be available f...

Classification of fMRI Time Series in a Low-Dimensional Subspace With a Spatial Prior
We propose a new method for detecting activation in functional magnetic resonance imaging (fMRI) data. We project the fMRI time series on a low-dimensional subspace spanned by wave...
