RESUMO
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.
