Horseradish peroxidase histochemistry was used to determine the course and extent of neuronal projections from the pontine taste area (PTA) to the gustatory neocortex (GN) in rat. Two distinct findings were encountered: (1) thalamocortical projections from posterior ventromedial thalamus to GN were confirmed, and (2) direct projections from cells located in the PTA to the GN were described. This novel anatomical finding supports previous suggestions that some gustatory information may be relayed to forebrain areas without making synaptic connection in the diencephalon.
用辣根过氧化物酶组织化学方法来确定大鼠脑桥味觉区（PTA）到味觉新皮质（GN）的神经投射路径和范围。得到了两个不同的发现：（1）证实了从丘脑后内侧核到GN的丘脑皮质投射，以及（2）描述了位于PTA的细胞到GN的直接投射。这一新的解剖学发现支持了之前的推测，即一些味觉信息可能在没有在间脑形成突触连接的情况下就被传递到前脑区域。
