Neurons of the prefrontal-premotor cortex, which had been studied electorophysiologically during a modified reaction time task, were identified by intracellular pressure micro-injection of horseradish peroxidase (HRP). The cells were classified into those showing a sustained vs. transient change in activity during performance of the task. Cells showing a sustained response were found to have their somata in layers III and VI and cells showing transient responses were found to have their somata in layers II and III. All cells were pyramidal cells with spiny dendrites.
在一项改良的反应时间任务中进行了电生理研究的前额叶-运动前区皮质神经元，通过辣根过氧化物酶（HRP）的细胞内压力微量注射进行鉴定。这些细胞被分为在任务执行过程中活动呈现持续变化与短暂变化的两类。发现表现出持续反应的细胞其胞体位于第III层和第VI层，而表现出短暂反应的细胞其胞体位于第II层和第III层。所有细胞均为具有棘状树突的锥体细胞。
