眶回

用猫以Fink&Heimer银浸法研究眶回后部的传出纤维投射，出现终末及终末前溃变的部位如下：双侧皮层的冠状回、乙状后回、S（？）

The efferent projections of the posterior part of the orbital gyrus were studied with the method of Fink-Heimer in eight cats .

眶回的前部，乙状前回外侧部的前部也有大量标记细胞。

There were also numerous labelled cells in the anterior parts of orbital gyrus and of the lateral zone of anterior sigmoid gyrus .

水牛副嗅球是嗅球内表面不明显的长条状隆起，长约12毫米，宽约4毫米，与额叶眶回内侧部相邻。

The accessory olfactory bulb is an inconspicuous elongated tubercle , lying on the medial surface of the olfactory bulb . The size of the tubercle is about 12 × 4 mm , adjacent to the medial part of protean gyrus in frontal lobe .

但两种任务中在左内侧眶额回、右侧杏仁体、双侧海马和前扣带回区域的激活有差异（P＜0.01）。

But activation at left medial orbitofrontal lobe , right amygdala , bilateral hippocampi and anterior cingulate gyri was different in the 2 tasks ( P0.01 ) .

结果：愉快及不愉快气体刺激均激活嗅觉中枢及相关的重要通路：海马回钩（BA28）、丘脑内侧背核、眶额回皮质（BA11，BA47）均出现明显激活。

Results : Activation was present in the olfactory centre and important tract during administration of pleasant and unpleasant odors . , such as uncus of hippocampus ( BA 28 ), lateral medial nucleus of thalamus and orbitofrontal gyrus ( BA11 , BA47 ) .

晚发抑郁症患者眶额回体积改变的磁共振成像研究

Orbital frontal cortex volumes changes in late-onset depression

结论：1.本研究进一步验证了海马回钩、丘脑内侧背核、眶额回为嗅觉中枢及其重要通路。

Conclusions : The uncus of hippocampus , lateral medial nucleus of thalamus and orbitofrontal gyrus are the olfactory centre and important tract .

结论降低梭状回，眶额回，杏仁核，下丘脑及腹侧纹状体的兴奋水平可能抑制食欲。

Conclusions : To reduce neurofunctional activation in posterior fusiform gyrus , OFC , amygdale , hypothalamus and ventral striatum might suppress the desire for food .

本研究进一步验证了海马回钩、丘脑内侧背核和眶额回为嗅觉中枢及其重要通路，并且右侧大脑半球为嗅觉优势半球；

The uncus of hippocampus , lateral medial nucleus of thalamus and orbitofrontal gyrus are further proved the olfactory centers and important pathways , and presented dominant in the right hemisphere .
