The effects of damage to the dorsal and medial cortex of turtles were investigated in two experiments. In the first, damage to the dorsal cortex disrupted acquisition and reversal of a go-no-go discrimination but had no effect on retention of the discrimination if it had been learned preoperatively. Medial cortex damage had no effect. In the second experiment, dorsal cortex damage impaired acquisition, but not extinction or reacquisition, of a discrete-trial keypress. Again, medial cortex damage had no effect. The results suggest that the dorsal cortex is involved in learning in turtles.
在两项实验中研究了对龟背侧和内侧皮质损伤的影响。在第一个实验中，背侧皮质损伤破坏了“去-不去”辨别任务的习得和反转，但如果该辨别任务是术前习得的，则对其保持没有影响。内侧皮质损伤没有影响。在第二个实验中，背侧皮质损伤损害了离散试次按键任务的习得，但不影响消退或重新习得。同样，内侧皮质损伤没有影响。结果表明，背侧皮质参与龟的学习过程。
