“The Survival of the Maze Habit After Cerebellar Injuries”, 1926 (; backlinks):
Practice was given 7 rats in the running of a maze until 10 errorless runs occurred in sequence, whereupon a rest of 10 days was introduced followed by a retention-of-the-habit test, then followed more practice until 10 errorless runs occurred in sequence again. Then systematic destruction of various areas of the animals’ cerebellums was effected through cautery.
After a period indicating complete recovery from the operation, the animals were tested for retention, and were then put through relearning trials.
Since the time records, error scores, and re-trials necessary for 10 errorless runs, after the operation, did not vary greatly from those obtained in the preliminary retention and relearning tests, before the operation, in both seeing and blind rats, Lashley concludes that the cerebellum plays no necessary part in the performance of the maze-running habit.
Includes: 3 figures of the normal anatomy of the rat’s cerebellum, 15 figures of the destroyed cerebellar areas, protocols of the behavior of the 7 rats, 2 tables, and 4 references are given.
