To analyse the olfactory bulb 55 counts/sec rhythm a frequency analyser with three narrow band filters was used, distortions introduced into recordings by these filters were corrected, the original 55 counts/sec rhythm was synthesised graphically by means of geometrical addition of the corrected frequency components, an electron device was designed for physical simulation of the above-mentioned rhythm and an example of a program for this rhythm synthesis, using this device, was given. After distortion corrections 'bursts' of 55 counts/sec rhythm frequency components are seen not as 'spindles', but as 'packets' of oscillations with the same amplitude (the oscillation amplitude varies only in different packets). These 'spindles of bursts' for 55 counts/sec rhythm are formed not due to the recruiting and then to the derecruiting of neurons (or of their elements), but to algebraic addition of activities of several neuron pools producing oscillation packets.
为了分析嗅球每秒55次的节律,使用了带有三个窄带滤波器的频率分析仪,对这些滤波器引入记录中的失真进行了校正,通过对校正后的频率成分进行几何相加,以图形方式合成了原始的每秒55次节律,设计了一种电子装置用于对上述节律进行物理模拟,并给出了一个使用该装置进行该节律合成的程序示例。经过失真校正后,每秒55次节律频率成分的“爆发”并非表现为“纺锤波”,而是表现为具有相同振幅的振荡“包”(振荡振幅仅在不同包中有所变化)。每秒55次节律的这些“爆发纺锤波”并非由于神经元(或其元件)的募集然后解募集而形成,而是由于几个产生振荡包的神经元池活动的代数相加而形成。
