The temporal trajectory of absolute angular velocity measured during a one hour long recording session is dependent upon the concentration of ethanol administered acutely during the session and on whether the fish were chronically pre-exposed to ethanol before. Mean ± S.E.M. are shown for 1-minute intervals of the recording session. The treatment conditions (group designations) are shown above the graphs. The values following the letter ‘C’ represent the concentration of ethanol (expressed as ethanol/water vol/vol %) employed during the chronic pre-treatment period (0.00 representing control and 0.50 the chronic ethanol exposed fish). The values following the letter ‘A’ represent the concentration of ethanol employed during the acute exposure, i.e. the behavioural recording, session (0.00 representing control, and 0.50 and 1.00 the corresponding acute ethanol exposed fish). Sample sizes (n) were as follows: C0.00A0.00 = 14; C0.00A0.50 = 13; C0.00A1.00 = 18; C0.50A0.00 = 13; C0.50A0.50 = 16; C0.50A1.00 = 10. Note the apparent reduction of S.E.M in the highest acute concentration groups (C0.00A1.00 and C0.50A1.00) compared to the other groups. Also note the increased S.E.M and also the increased mean of absolute angular velocity in the ethanol withdrawal group (C0.50A0.00).
