THE

Inbr. F32 (Tsukuba, 1984).

Characteristics

Ambulaton score under these conditions is very low, with the rats remaining essentially passive (Fujita 1984). Shorter latency, more digging activity and longer length burrows, with most rats escaping into burrows following a loud crashing sound than F344 or TLE (Kitaoka et al, 1994).
