Chimney Test (from Boissier et al. 1960)
The chimney is constituted of a vertical glass tube (length 30 cm, diameter: 26 or 28 cm depending on the weight of mice). Mice were put in the tube, the head upside down. The test consisted of determining the time taken by mice to climb back, upside down, up to 25 cm of height. A positive response was scored if mice passed the delineation corresponding to 25 cm in less than 30 sec. Mice were tested once. Results were expressed as percentage of success. Forty-eight 129sv/C57BL/6 mice (20 +/+, 28 -/-) were studied.
