6.在同一矢状面上，穿过VB背腹侧的前后多排微电极与神经元相遇，这些神经元的感受野从身体近端逐渐移至远端。但不同的微电极往往会在相同的深度遇到相同的接受场。7.在VB中，前后延长的同位素注射标记的3a、3b、1或2区比内侧或背腹延长的注射要小得多。8.结果提示VB的一种基本组织结构，其中狭窄的、前后伸长的VB成分代表体表的一小部分，并不同地投射在第一躯体感觉区的细胞构筑区域上。
6. Anteroposterior rows of microelectrode penetrations traversing the dorsoventral extent of VB in the same parasagittal plane encounter sequences of neurons whose receptive fields gradually shift from proximal to distal body parts. But the same receptive fields tend to be encountered at the same depth by the different microelectrodes. 7. Anteroposteriorly elongated injections of isotope in VB label a far less extensive part of areas 3a, 3b, 1, or 2 than mediolaterally or dorsoventrally elongated injections. 8. The results suggest a fundamental organization of VB in which narrow, anteroposteriorly elongated components of VB represent small parts of the body surface and project differentially on the cytoarchitectonic fields of the first somatosensory area.
