The influence of the hour of the day on the performance of male rats in water multiple T-maze.
The performance of male SD rats in the water multiple T-maze was tested at 2 different times of the day: during the dark phase from 1900 to 2100, the elapsed time between the entry into water and the arrival at ramp was significantly shorter and the number of errors significantly less in comparison with the results of another group of male rats allowed to swim during the light phase from 0700 to 0900. However, only the acceptance of information was retarded, while the keeping of memory remained unaffected.
