Behavioral profile of zebrafish larvae during a one-hour exposure to vehicle or PTZ.

<p>The average movement (y-axis) of vehicle- and 20 mM PTZ-treated larvae are denoted by closed triangles (grey) and closed circles (black) respectively. The mean movement ± SD of 12 larvae is depicted per minute (x-axis) of the tracking session. By 15 min, the frequency of convulsion-like episodes in all larvae reached a rate of one or more per minute, which is reflected in the decrease in SD after this time point.
