Assessment of the Central Effects of Natural Uranium via Behavioural Performances and the Cerebrospinal Fluid Metabolome

Figure 4

Locomotor activity and anxiety-like behaviour of male rats exposed to 1.5, 10, or 40 mg⋅L⁻¹ NU from birth for 9 months. (a) shows the number of visits to the closed arms of the elevated plus maze and reflects locomotor activity. (b) shows the time spent, expressed in seconds (s), in the closed arms of the elevated plus maze and reflects anxiety level. The data are presented as mean ± SEM; for each group; NU: natural uranium; , significant difference from control.
