It's great that this student has undertaken a science project of this type - it shows that she has ambition and could be a scientist one day.

Until that day, she should let her analysis of the data to the trained professionals.

All she did was show that snail neural cells, when placed in a foreign environment, are susceptable to the effects of an ionized substance. Odds are that salt would do the same as MSG in this study.
It is glutamate that is found in the blood serum - not Monosodium Glutamate. Perhaps the 17% sodium in the mix caused these issues??

All this turns out to be is another sensationalistic anti-MSG report that doesn't hold water.

Cheers!
