In newly born rhesus monkeys, a delayd response task and its modified version, a hiding task, were trained with use of the hand. To perform the task in a freely moving experimental room, the monkey had to open a small bottle cap with either hand and to pick up a piece of apple with either hand and bring it to the mouth. The monkey learned the task with 3-5s delay period in 2-4 months after birth. During the course of the learning the hand movement and the task, a GABA agonist, Muscimol and a GABA antagonist, Bicuculline methiodide, were injected directly into the motor area, premotor association arca and prefrontal cortex and disrupted movement and performence were observed. It was found that the GABA had an important role to learn a visually guided hand movement in the motor area, premotor assocition area and prefrontal cortex and that in each area specific function develops, i.e.initiation of the movement in the motor area, visuo-movement association and skill in the premotor association area and spatial working memory in the prefrontal cortex.

在刚出生的恒河猴中，用手训练了延迟反应任务及其修改版本（隐藏任务）。为了在自由移动的实验室中执行任务，猴子必须用两只手打开一个小瓶盖，并用两只手拿起一块苹果并将其放入嘴里。猴子在出生后2-4个月内，经过3-5秒的延迟时间才学会了这项任务。在学习手部动作和任务的过程中，将 GABA 激动剂蝇蕈醇和 GABA 拮抗剂甲碘荷包牡丹碱直接注射到运动区、前运动关联弧和前额皮质，观察到运动和表现受到干扰。研究发现，GABA 在学习运动区、前运动关联区和前额叶皮层的视觉引导手部运动方面发挥着重要作用，并且在每个区域中，特定功能得到发展，即运动区的运动启动、前运动关联区的视觉运动关联和技能以及前额叶皮层的空间工作记忆。
