Exploration of Cortical Dynamics in the Center-Out with Stylus Paradigm

This study aims to identify correlations between the directions of the hand movements and the brain signals recorded from the brain surface using electrocorticography (ECoG). We suppose that the coding of the hand movement direction occurs in the motor cortex and could be detected with ECoG. Using representational similarity analysis (RSA) and the cosine tuning assumption we confirmed that indeed, there is a significant concordance between the brain signals and the hand movement directions. And the main areas of the brain responsible for this have been identified.
