Spontaneous alternation and habituation in a t-maze in nervous mutant mice

Nervous mutant mice have a selective degeneration of Purkinje cells and deep cerebellar nuclei. In comparison with littermate controls, nervous mutant mice did not alternate spontaneously in a successive trial procedure (six consecutive trials per day) and did not habituate in a restricted part of a t-maze in a 4-min session. These data indicate that the cerebellum may have a role in spatial learning.
