Resumo
A kinetic model is presented that describes the pulse of the oxygen level increase in the excited nervous tissue of the human brain in response to an external signal. The model is based on biochemical data and describes experimental data on the hemodynamic impulse response. The model predicts the dynamic behavior of process participants preceding the oxygen pulse and determining the BOLD signal level.
