- BPA during early development led to increases in neuron and glia number in the prefrontal cortex of male, but not female, rat offspring.
- An increase in both neurons and glia in this brain region is characteristic of many human children diagnosed with autism.
- This interesting finding is currently being followed up with more measures relevant to models of autism in the current study of early BPA exposure.
- BPA exposure during adolescence changed the number of glia in adults such that exposed males had glia numbers more like control females and exposed females had glia numbers more like control males.
