Diversity of neural-hemodynamic relationships associated with differences in cortical processing during bilateral somatosensory activation in rats

► Neural-hemodynamic relationships during unilateral/bilateral rat hindpaw stimulation. ► Ipsilateral CBV-related responses showed mediocaudal shifts relative to contralateral ones. ► LFP-CBV relationships differ between contra- and ipsilateral responses to unilateral stimulation. ► LFP-CBV relationships showed nonlinearity in terms of overall responses to bilateral stimulation. ► γ-Band LFP-MUA-CBV relationships, however, showed linear patterns across unilateral/bilateral stimulation.
