New Research Reveals Hidden Window of Vulnerability in Baby Brains. Scientists have made a groundbreaking discovery by analyzing the layers of baby teeth, which has led to a surprising finding about the impact of toxic metals on developing brains. According to their research, there is a critical period in early childhood when baby brains are most susceptible to the damaging effects of toxic metals, such as lead and mercury. This newfound understanding could have significant implications for the prevention of behavior problems later in life, as exposure to these toxins during this vulnerable window may be linked to an increased risk of developmental and behavioral issues.
By analyzing layers in these teeth, scientists have pinpointed a critical window when baby brains are most vulnerable to toxic metals — and linked that to behavior problems later in life.
