Abstract
The effect of deafferentation of the rat olfactory bulb on bulbar TRH concentration was studied. TRH concentrations in the lesioned bulbs did not decline when compared to concentrations in sham-lesioned bulbs for the post-lesion intervals of 1 h through 14 days. Since TRH concentrations did not decline following deafferentation, TRH in the olfactory bulb does not derive from centrifugal neurons.
摘要
研究了大鼠嗅球去传入对球内促甲状腺激素释放激素（TRH）浓度的影响。在损伤后1小时至14天的时间段内，与假手术损伤嗅球中的浓度相比，损伤嗅球中的TRH浓度并未下降。由于去传入后TRH浓度没有下降，因此嗅球中的TRH并非来自离心神经元。
