activity in an open-field, exploration of a hole-board, motor coordination in the coat-hanger
test, and spatial learning in the Morris water maze. B6 mice displayed a higher number of
segment crossings in the open-field and of hole-poking responses than A/J mice. The
performance of B6 mice was superior to that of A/J mice not only in the submerged but also
in the visible platform version of the Morris water maze. By contrast to their hypoactivity, the …
