已往认为嗅球与前嗅核、梨状前区皮质及皮质杏仁核有联系。认定嗅球脑干之间有广泛往返联系的文章还没有见到。我们继1984年在全国解剖学年会上宣读了嗅球向脑干的广泛投射之后,近年来又进一步用荧光标记法研究了脑干向嗅球的投射。意外发现,脑干 In the past that the olfactory bulb and the former olfactory nucleus, pear-like cortex and cortical amygdala associated. The article that found extensive reciprocation between the olfactory bulb brainstem has not been seen. Following the extensive projection of the olfactory bulb to the brainstem at the annual meeting of the National Anatomy in 1984, we further investigated the projection of the brainstem into the olfactory bulb by fluorescent labeling in recent years. Accidental discovery, brain stem
