|WASHINGTON - Exposure to ultrasound can affect fetal brain development, a new study suggests. But researchers say the findings, in mice, should not discourage pregnant women from having ultrasound scans for medical reasons.|
When pregnant mice were exposed to ultrasound, a small number of nerve cells in the developing brains of their fetuses failed to extend correctly in the cerebral cortex.
"Our study in mice does not mean that use of ultrasound on human fetuses for appropriate diagnostic and medical purposes should be abandoned," said lead researcher Pasko Rakic, chairman of the neurobiology department at Yale University School of Medicine.
However, he added in a telephone interview, women should avoid unnecessary ultrasound scans until more research has been done.

|I wonder if the increased rates of autism could be linked to increased use of ultrasound. I know heavy metal toxicity is the favored hypothesis today but u/s use makes a lot of sense, the more that I think about it.|

But I really don't like the stores that offer the 4D u/s that's too weird and dangerous.
