Calcium-45 influx was measured in squid axons during excitation. Different stimulation frequencies changed this influx and general concentration of calcium ions in squid axons. The maximum influx was recorded at the frequency 10 imp/s and 30 imp/s. Calcium influx and general content of calcium ions in axoplasma during excitation was independent of the number of excitation impulses. The role of sodium and calcium channels during excitation is discussed.
在兴奋过程中测量了枪乌贼轴突中的钙-45内流。不同的刺激频率改变了这种内流以及枪乌贼轴突中钙离子的总体浓度。在10次冲动/秒和30次冲动/秒的频率下记录到最大内流。兴奋过程中轴浆内的钙内流和钙离子总体含量与兴奋冲动的数量无关。文中讨论了钠通道和钙通道在兴奋过程中的作用。
