Interthalamic adhesion is an inconstant part of the human diencephalic neuroanatomy, which some histological studies have indicated it is a gray commissure and others a white commissure. Its presence has been associated with alterations in health status, including schizophrenia, psychotic states, and hydrocephalus. Thirty-one fresh human brains were evaluated randomly, to determine the presence of interthalamic adhesion and its histological composition, by way of lamina terminalis puncture of the third ventricle. Photographic records were taken and histological processes was performed by hematoxylin-eosin staining, in the case of the existence of the adhesion. It was found that 51.71% did present interthalamic adhesion, and on histological examination, no neuron bodies were found in the median part, which implies that does not correspond to a gray commissure, but interthalamic adhesion in humans is variable, with a predominance of glial cells. There is no gray commissure in human interthalamic adhesions.
丘脑间粘合是人类间脑神经解剖结构中一个不恒定的部分，一些组织学研究表明它是灰质连合，而另一些研究则表明它是白质连合。其存在与健康状况的改变有关，包括精神分裂症、精神状态和脑积水。随机评估了31个新鲜人脑，通过第三脑室终板穿刺来确定丘脑间粘合的存在及其组织学组成。进行了摄影记录，对于存在粘合的情况，通过苏木精-伊红染色进行组织学处理。结果发现，51.71%的人脑存在丘脑间粘合，组织学检查显示，中间部分未发现神经元体，这意味着它不对应于灰质连合，但人类的丘脑间粘合是可变的，以胶质细胞为主。人类丘脑间粘合中不存在灰质连合。
