MeHg altered the developmental form of short-term synaptic plasticity (STP) in the visual cortex of rat in a MeHg exposure time-dependent manner. Representative recordings of paired-pulse responses in slices prepared from rats treated with 0.9% NaCl (Top), 0.75 (Middle) and 1.5 mg/kg/day MeHg (Bottom), respectively, for 15 or 30 days or 30 days injections plus extra 30 days of “clearance”(total 60 days). Each trace is a representative example of 6 - 8 individual experiments.
