Comparison between presence (green bar) and absence (red bar) of visual stimulation for the mean \(a_{ij}\) coefficient representing the causal influence of MT on V1 in the four different datasets. Bars indicate the mean values and the standard deviation of the mean. Higher values of the coefficients are obtained in data sets with better quality parameter Q, as shown by blue crosses
