a trend towards significanceP = 0.094
The interaction treatment × stimulation was significant in the bdnf +/+ line (F 1,2811 = 4.206, P = 0.040, partial η 2 = 0.00) and showed a trend towards significance in the bdnf -/- zebrafish (F 1,2637 = 2.809, P = 0.094, partial η 2 = 0.00), suggesting subtle differences in the response to repeated stimulations in the two lines.
