•A bimodal IOI—calcium imaging system was used to record resting state activity.•Neuronal and glial parts of fluorescence signal were retrieved with frequency filters.•Hemodynamic response and fluorescence signals correlation was computed.•Differences in correlation patterns were found between high...
