In white anesthetized rats electric stimulation of n. anterodorsalis and light stimulation evoked potentials in the retrosplenial cortex, field 29. The EPs were surface-negative, multicomponent, their latency at the n. anterodorsalis stimulation being 5.1 +/- 0.6 (with a range of 2-7) msec, at the light stimulation -- 21 +/- 1.7 (with range of 15-30) msec. The EPs in the field 29 at low-frequency rhythmic light stimulation and at n. anterodorsalis stimulation (1-5/sec) revealed the phenomenon of habituation and driving. The layer analysis of the light EPs showed reversal of polarity in the upper part of layer V of the cortex, while after n. anterodorsalis stimulation the reversal of polarity occurred beneath the layer VI. The possibility of existence of several thalamis visual inputs in the field 29, is discussed.
在白色麻醉大鼠中，电刺激背前神经和光刺激可在29区脾后皮质诱发电位。这些诱发电位为表面阴性、多成分，电刺激背前神经时其潜伏期为5.1±0.6（范围为2 - 7）毫秒，光刺激时为21±1.7（范围为15 - 30）毫秒。在低频节律性光刺激和电刺激背前神经（1 - 5次/秒）时，29区的诱发电位表现出习惯化和驱动现象。对光诱发电位的分层分析显示，皮质V层上部出现极性反转，而电刺激背前神经后，极性反转发生在VI层下方。文中讨论了29区存在多个丘脑视觉输入的可能性。
