Table 1 The definitions of behavioural parameters in the novel tank

From: Reversal of reserpine-induced depression and cognitive disorder in zebrafish by sertraline and Traditional Chinese Medicine (TCM)

Behavioural parameters Definition
Total distance travelled (m) The total distance in the novel tank
Average velocity (cm/s) The direction and magnitude of zebrafish speed in the novel tank
Turn angle (°) The total turning angle of zebrafish in the novel tank
Angular velocity (°/s) The direction and magnitude of zebrafish angular speed in the novel tank
Meandering (°/s) The degree of turning vs. travel distance
Average entry duration in the top (s) The amount of time spent at the top of the novel tank during each crossing
Distance travelled in the top (m) The total distance moved in the defined top part in the novel tank
Time spent in the top (s) The total time spent in the top part of the novel tank
Latency to enter the top (s) The amount of time to first cross from the bottom part to the top of the novel tank
Number of entries to the top The number of crosses from the bottom part to the top of the novel tank
Time spent ratio of top: bottom The ratio of the time spent on top over bottom
Distance travelled ratio of top: bottom The ratio of the total distance moved in the top part vs. the bottom
Entries ratio of top: bottom The number of crosses from the bottom part to the top of the novel tank
Freezing bouts (frequency) The total number of instances of immobility (> 1 s) during the 5 min test in the novel tank
Freezing duration (s) The duration of all freezing bouts in the novel tank
