摘　　要：为了研究头—盆向超重对大脑功能状态的影响,本实验观察分析了在不同G 值的头—盆向超重作用下,清醒家兔听觉诱发电位的中晚期成分。结果表明,超重作用对脑中枢不同层次有着不同程度的影响,较高G 值作用对皮层慢电位影响最明显,有可能反映超重作用对脑的高级整合功能的影响最为严重。In order to investigate the effects of +Gz stress on brain funtion,the medium- and long-latency auditory evoked responses in consciousrabbits during different levels of +Gz stress were analysed.Theresults showed that the effects varied in different levels of the spe-cific auditory system,and that higher G stresses had serious influen-ces upon SCR.It reflected that there might be detrimental effectson the integrative function of brain.
