Motor responses (MRs) of single vibrissae and facial muscles in alert rabbits to intracortical microstimulation (ICMS) were observed visually and recorded by means of photodiodes. Moderate ICMS evoked only contralateral MRs of long caudal vibrissae; however motor responses of short rostral vibrissae, rostral part of the upper lip and lower jaw were often bilateral. Two levels of low-threshold ICMS were revealed in the cortical layers: at the depth of 0,6-1,0 mm and of 1,4-1,8 mm. Motor representation of vibrissae occupies a large territory within the frontal cortex, 1,5-3,5 mm laterally from the sagittal suture and 0-10 mm rostrally from bregma. Lip and jaw representations are located laterally from the vibrissal field, with some overlapping.
通过视觉观察并利用光电二极管记录了警觉家兔单根触须和面部肌肉对皮质内微刺激（ICMS）的运动反应（MRs）。适度的ICMS仅诱发长尾部触须的对侧MRs；然而，短吻部触须、上唇和下颌吻部的运动反应通常是双侧的。在皮质层中发现了两个低阈值ICMS水平：深度为0.6 - 1.0毫米和1.4 - 1.8毫米处。触须的运动代表区在额叶皮质内占据较大区域，从矢状缝向外1.5 - 3.5毫米，从前囟向前0 - 10毫米。唇部和下颌的代表区位于触须场的外侧，有一些重叠。
