The application of two kinds of ventilatory interoceptive influences with opposite effects on the acid-base balance (hyperventilation and breath holding) results in appearance of late nonspecific after-effects in human EEG, which do not disappear until the 30th min after the stimulation. They consist in local and spatial synchronizing processes in the alpha and beta EEG spectrum, being most pronounced in the beta-2 range (23-36 Hz). These changes are considered as a sign of a development of readjustment in the functional state of the central nervous system in the direction of its improvement. The triggering of this readjustment is largely determined by the considerable changes in the internal medium, leading to intensified interoceptive signalization (mechanical, chemical and proprioceptive), as well as to the development of a brief cerebral hypoxy, followed by improved brain blood flow.
两种对酸碱平衡具有相反作用的通气性内感受影响（过度通气和屏气）的应用，会导致人类脑电图中出现晚期非特异性后效应，这种效应在刺激后30分钟才会消失。它们表现为脑电图α和β频段的局部和空间同步过程，在β-2范围（23-36赫兹）最为明显。这些变化被认为是中枢神经系统功能状态朝着改善方向进行重新调整的一个标志。这种重新调整的触发很大程度上取决于内部环境的显著变化，这会导致内感受信号增强（机械性、化学性和本体感受性），以及短暂性脑缺氧的发展，随后脑血流量增加。
