Beta electrocorticographic rhythms (40 Hz) develop during motionless focused attention in two distinct cortical foci in cats. A cytoarchitectonic study was performed to determine the precise location of these foci. Electrode tips recording beta rhythms were found: (i) in motor areas 4 gamma and 6a beta, in a band extending from the postcruciate cortex to the walls of the presylvian sulcus, crossing the frontal pole (anterior beta focus); (ii) in the posterior parietal associative area 5a, along the divisions of the ansate sulcus, extending to the mesial aspect of the hemispheres (posterior beta focus). The two foci are separated by areas 3, 2 and 1, where beta rhythms were never recorded. The fact that both these areas, containing giant pyramidal cells, develop a specific type of activity during immobility may have a functional meaning: area 5 may be involved in the cat as it is in the monkey in the control of motor behaviour.
β脑电图节律（40赫兹）在猫静止且注意力集中时，于两个不同的皮质区域产生。进行了细胞构筑学研究以确定这些区域的精确位置。发现记录β节律的电极尖端位于：（i）运动区4γ和6aβ，在从十字后皮质延伸至前薛氏沟壁、穿过额极的带状区域（前β焦点）；（ii）后顶叶联合区5a，沿着袢状沟的分支，延伸至半球的内侧（后β焦点）。这两个焦点被3区、2区和1区分开，在这些区域从未记录到β节律。这两个区域都含有巨大锥体细胞，且在静止时会产生特定类型的活动，这一事实可能具有功能意义：5区可能如在猴子中一样，在猫中参与运动行为的控制。
