本文还讨论了嗅球神经细胞的内在活动对嗅觉信息传导的影响。兔子的灯泡显示2个潜在的节奏，大波在50/秒。由强烈的嗅觉刺激和由于二尖瓣细胞的同步活动引起，以及高达100/秒的较小波。这是由于不在直接途径上的细胞的内在活性。这种活动暂时受到嗅觉信号的抑制，但稍后会恢复并干扰信号的传输。嗅觉适应可能是由于这一点，因为在重复吸入气味后嗅觉器官中没有适应。
The effects of the intrinsic activity of nerve cells in the bulb on the conduction of olfactory messages are discussed. The rabbit''s bulb shows 2 potential rhythms, large waves at 50/sec. caused by strong olfactory stimuli and due to synchronous activity of mitral cells, and smaller waves up to 100/sec. due to intrinsic activity of cells not on the direct pathway. This activity is temporarily suppressed by olfactory signals, but returns later and interferes with the transmission of signals. Olfactory adaptation may be due to this, as there is no adaptation in the olfactory organ after repeated inspiration of a smell.
