In experiments on awake relatively unrestrained pigeons, studies have been made on the reactions of the cerebrovascular bed to fixed functional loads of physical (orthostasis) and chemical (inhalation of hypoxic and hypercapnic gas mixtures) nature. Using hydrogen clearance method, the increase in the intensity of local cerebral blood flow in different structures of the telencephalon during inhalation of the mentioned gas mixtures was demonstrated. Bilateral vagotomy resulted in inversed reactions. Influence of functional loads was accompanied by changes in rheoencephalographic parameters. The data obtained suggest the existence of an evident reactivity of cerebral vessels in birds which is controlled by neurogenic mechanism of regulation of vascular tone.
在对清醒且相对不受约束的鸽子进行的实验中，研究了脑血管床对物理性（直立位）和化学性（吸入低氧和高碳酸气体混合物）固定功能负荷的反应。采用氢清除法，证实了在吸入上述气体混合物期间端脑不同结构中局部脑血流强度的增加。双侧迷走神经切断术导致反应相反。功能负荷的影响伴随着脑电阻图参数的变化。所获得的数据表明鸟类脑血管存在明显的反应性，这种反应性受血管张力调节的神经源性机制控制。
