Strategy analysis on the 4/8 radial arm maze. (a) Dcdc2^del2/del2 mice showed a greater preference for making 45° (adjacent) arm entries in comparison to WT. Further within subject analysis of Dcdc2^del2/del2 turn angles also revealed that subjects made significantly more 45° turns, overall, than turns 90° or more. (b) However, examination of average turn angle indicate that both Dcdc2^del2/del2 and WT mice had comparable mean turn angles, suggesting that Dcdc2^del2/del2 also had to make a number of larger turn angles greater than 90° together with the increased incidence of 45° turn angles. *P<0.05; **P<0.01
