Effect of constant light exposure on anxiety and fear-related behavior. To elaborate the effect of constant light exposure on locomotor activity and fear-related activity, the open-field test, balance beam test and tonic immobility test were performed. A The times of first step; B-F The counts of grid number, defecation, steps, escape and vocalizations in the open field test; G Times stayed in balance beam test; H The distance moved in balance beam test; I The immobility time in tonic immobility test. Values are mean ± SEM (LD, n = 39, LL, n = 40); **P < 0.01, compared with LD. The data were analyzed using U-Test with SPSS 20.0
