本文研究了未麻醉恒河猴顶叶Brodmann区5区单个神经元对生理躯体感觉刺激的反应。大多数神经元对皮肤和深层组织的光机械刺激和/或关节旋转敏感，这些神经元与初级躯体感觉区神经元的区别在于：多关节相互作用、同侧感受野、双侧相互作用、前肢和后肢或躯干之间的相互作用以及关节和皮肤刺激的兴奋性相互作用。有些是高度选择性的，因为它们只对涉及关节和皮肤的某些关键刺激模式做出反应。这一结果支持以下假设：5区是从丘脑系统接收到的躯体感觉信息的高级加工场所，并可能产生身体和触觉物体在三维空间中的位置和形状的神经编码。
The response of individual neurons within Brodmann's area 5 of the parietal lobe to physiological somesthetic stimuli was studied in unanesthetized rhesus monkeys. Most neurons were sensitive to light mechanical stimulation of the skin and deep tissue and/or joint rotation.These neurons were distinguishable from those of the primary somatosensory area by several characteristics: multiple joint interaction, ipsilateral receptive field, bilateral interaction, interaction between forelimb and hindlimb or trunk, and excitatory interaction of joint and skin stimuli. Some were highly selective, in that they responded only to certain critical patterns of stimuli involving both joint and skin. The results were viewed as supporting the hypothesis that area 5 is the site of higher order processing of somesthetic information received from the lemniscal system, and may give rise to the neural code of position and form of body and tactile objects in 3-dimensional space.
