We demonstrate experimentally that noise can enhance the homeostatic function in the human blood pressure regulatory system. The results show that the compensatory heart rate response to the weak periodic signal introduced at the venous blood pressure receptor is optimized by adding noise to the arterial blood pressure receptor. We conclude that this functional stochastic resonance most likely results from the interaction of noise with signal in the brain stem, where the neuronal inputs from these two different receptors first join together.
我们通过实验证明，噪声可增强人体血压调节系统中的稳态功能。结果表明，通过向动脉血压感受器添加噪声，可优化对静脉血压感受器引入的微弱周期性信号的代偿性心率反应。我们得出结论，这种功能性随机共振很可能是由于噪声与脑干中的信号相互作用所致，来自这两种不同感受器的神经元输入首先在脑干中汇聚。
