focus area up to 2000x1088 pixels, Basler, Ahrensburg, Germany) and a video recording software (Hiris, R&D vision, France). Four circular swim arenas (with a 2.2 cm inner diameter, 2 mL system water filled with an estimated height of 525 µm) with one larva in each were placed above a plexiglass plate on which 2 speakers (Monacor, 10W) were attached. A flat LED plate (R&D vision, France) with a polarized optical filter was placed below the transparent plexiglass to provide homogeneous field illumination. Fish were allowed to acclimate for 10 min. The exploratory locomotion was recorded for 5 min at 160 fps. The video software was then switched to record the acoustic stimulus evoked escape behaviors at 650 fps for one second. To trigger escape behaviors, a 500 Hz, 5ms sine wave stimulus was delivered through a class D amplifier (Adafruit, MAX9744) over the two speakers at maximum volume 200 ms after the onset of recording. Each larva was subjected to ten stimuli, with 3 min inter-trial interval.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
