2.   Because mercury is toxic to developing brains, she said, children are most vulnerable.

3.   But such studies do little to quiet concerns about long-term effects on developing brains.

4.   Even the incidence of so-called silent lead poisoning -- the low levels that have hidden effects on the developing brain -- has dropped precipitously.

5.   Much of the discussion about environmental health focuses on fetuses and infants, whose developing brains and bodies are highly vulnerable to toxins.

6.   Neuroscientists who study the developing brain have long sought to understand just how that extraordinary neuronal circuitry gets wired up in the first place.

7.   Our bodies need iodine to make the thyroid hormone thyroxine, which is vital for developing brains.

8.   The clear message is that glia are a major source of neurons in the developing brain.

9.   The new gene is of particular interest because its role is to switch on a cascade of other genes in the developing brain of the fetus.

10.   The new studies also evoke the image of the developing brain as a kind of Parisian parfumerie, where chemistry reigns and entices.
