The laminar distribution of excitatory responses to iontophoretically applied acetylcholine (ACh) was studied in the first somatic sensory cortex (SI) of the Rat, using extracellular dye deposits for reconstruction of the electrode tracks. Most of the responses were recorded from neurons located in the lower half of the cortex, namely in layers V and VI. ACh sensitive neurons were found in two locations: one encompassing layer V and upper part of VI and the other at the border between cortex and white matter. The functional significance of this distribution is discussed.
使用细胞外染料沉积来重建电极轨迹，研究了离子电渗法施加乙酰胆碱（ACh）时大鼠第一体感皮层（SI）中兴奋性反应的层状分布。大多数反应记录自位于皮层下半部分的神经元，即V层和VI层。在两个位置发现了对ACh敏感的神经元：一个包括V层和VI层上部，另一个位于皮层与白质的边界。讨论了这种分布的功能意义。
