Studies have been made of the dependence of neuronal reactions in the olfactory bulb of the newt on the pattern of presentation of a test solution (glutamine 10(-5) M) into the nasal cavity. Responses to stimulation at a frequency 6/min (which corresponds to the minimal rhythm of normal buccal movements) varied in the intensity and sign. The peak of excitation was usually observed after the 2nd or the 3rd stimuli. The increase of stimulation frequency up to 12-24/min increased the number of the inhibitory reactions and the intensity of inhibition. Replacement of rhythmic flow by a constant one results in inhibition of 34% of neurones which reacted by activation to the rhythmic series of 6/min. The data obtained are discussed in relation to the pattern of olfactory perception in newts under natural conditions.
针对蝾螈嗅球中神经元反应对测试溶液(10(-5) M谷氨酰胺)注入鼻腔模式的依赖性进行了研究。以6次/分钟的频率(对应正常颊部运动的最小节律)进行刺激时,反应的强度和特征各不相同。通常在第2次或第3次刺激后观察到兴奋峰值。将刺激频率提高到12 - 24次/分钟会增加抑制性反应的数量和抑制强度。用持续流动代替节律性流动会导致34%对6次/分钟节律性系列刺激产生激活反应的神经元受到抑制。结合蝾螈在自然条件下的嗅觉感知模式对所得数据进行了讨论。
