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
