But modern automobiles are filled with electronic weasel works and the mice mazes of computerhood.
Frequently pictured posing by the famous Number 10 front door, Humphrey's primary duties involved catching mice and rats in the maze of Downing Street buildings.
At the bottom, the men boarded trains that clanked and jerked along wooden tracks through a maze of silent tunnels, empty except for the occasional mouse scurrying.
Visuo-spatial learning and memory were assessed in male and female mice of 13 inbred strains on a small diameter mouse version of the Barnes maze surrounded by a wall and intra-maze visual cues.
In the cross-maze, mice of both genotypes showed a comparable number of different arm choices within every set of 4 arm entries (WT: 3.28±0.04; KO: 3.19±0.06; p>0.3) and their performance was not affected by stereotyped response patterns (% chaining: WT: 19.99±3.65; KO: 24.37±5.05, p>0.4), suggesting that spontaneous alternation is not impaired in KO mice.
Urine donor mice and sensor mice trained in the Y maze were of the inbred strains C57BL/6J (B6: MHC type H2b) and its congenic partner strain C57BL/6J-H2k C57BL/6J-H2k type H2k).
We confirmed the beneficial effects of tau ablation on Barnes maze performance of Scn1aRX/+ mice in 2 additional cohorts (cohorts 3 and 7; n = 17 23 mice per genotype; 5 months of age; see Supplementary Tables S1 and S2, and data not shown).
Animal testing, also known as animal experimentation, animal research, and in vivo testing, is the use of non-human animals in experiments (although some research about animals involves only natural behaviors or pure observation, such as a mouse running a maze or field studies of chimp troops).
In another study in mice spatial water maze training evoked expression of c-fos in DGCs that were 6 weeks old, but not in 1 week-old BrdU-labeled cells [31], [33], [51].
WT and P2X7R−/− mice of the Y-maze groups were subjected to a 5-min test in the Y-maze with 30-min ITI.
