Figure 4From: Effect of maternal excessive iodine intake on neurodevelopment and cognitive function in rat offspringSchematic of experimental timeline. The rats were fed with the low iodine diet and administered with different drinking water from pre-pregnancy (12 weeks) until their pups reached PN21. LI (1.2 μg/d); NI (5–6 μg/d); 3HI (15–16 μg/d). The pups from the rat mothers of each treatment group (LI, NI, and 3HI) were permitted free access to normal food and water from PN21 until PN45. G, gestational day; PN, postnatal day; MWM, Morris water maze.Back to article page
