Temporal profiles of Δ[HbO 2 ], Δ[HbR], and Δ[HbT] in (a) ipsilateral side and (b) contralateral side during and after FPI experiment for 1.6 a.t.m. Δ[HbR], and Δ[HbT] dropped immediately upon impact in ipsilateral side. After the procedure of respiratory treatment, the rebreathing from apnea resulted in that all of Δ[HbO2], Δ[HbR] , and Δ[HbT] increased
