Effects of gestational and postnatal exposure to methylmercury on spontaneous locomotor activity of the Wistar offspring rats (n = 20) in the open field test. In A, representative heat map of control and MeHg-exposed groups performances in open field. Results are expressed as mean ± SEM of B: total distance traveled (m); C: total distance traveled in the central area (s); and D: peripheral distance, both in meters (m). *Student’s t-test, p < 0.05.
