 Abstract: The BOLD effect in response to activation is sensitive to the concentration change of deoxy-Hb, which in turn is dependent on CBF, CBV and CMRO2. To relate these quantities, Buxton et al. proposed a balloon model based on the distensibility of the venous vessels. Here, we develop an extension to the current model in modelling the dynamics of deoxy-Hb and CBV not only in the venous part but in all vascular compartments and their individual intra- and extravascular contributions to the BOLD effect. Thus, the new model can predict outcomes of high-resolution imaging and solve apparent contradictions in experimental data.
