The visually driven instrumental conditioning of a single monkey (Macaca mulatta) was conducted after single-dose cranial irradiation with high-energy protons. The monkey executed saccades toward the visual stimuli and then responded by manually pressing right or left lever for stimuli in right or left half-field, respectively. The percentage of correct responses with dominant right hand exceeded the percentage of such responses with left hand and temporarily decreased two months after irradiation. A month later, the percentage of correct right-hand responses returned to the level before irradiation. No significant dynamic was found for changes in percentage of correct left-hand responses. The proton irradiation effect on right-hand responses suggests possible short-term disturbances in the eye-hand coordination for right handedness while the visual perception remains unaffected.

颅内高能质子辐照对猴子黏膜运动行为的影响。

在用高能质子进行单剂量颅骨照射后，对单只猴子（猕猴）进行视觉驱动的仪器调节。猴子朝着视觉刺激进行扫视，然后通过分别在右或左半场中手动按压右或左杠杆进行刺激来做出响应。占优势的右手正确反应的百分比超过了左手此类反应的百分比，并且在照射后两个月暂时下降。一个月后，正确的右手反应的百分比恢复到辐照前的水平。没有发现正确的左手反应百分比变化的显着动态。
