Yes, and for us, those pathways are also affected by excitotoxins (the worst for us was MSG) -- have a quick gander at some of the obvious foods you might eat, like noodles, chicken-flavoured potato chips, soups (anything beef/chicken/veggie flavour) it literally has like 50+ alternative names to hide it:
Flavour enhancer 621,
monosodium salt,
monohydrate,
monosodium glutamate,
monosodium glutamate monohydrate,
monosodium L-glutamate monohydrate,
MSG monohydrate,
sodium glutamate monohydrate,
UNII-W81N5U6R6U,
L-Glutamic acid,
glutamic acid,
monosodium salt, and
monohydrate.
and if you think it could be a cause, check out the actual only scientific article that comes up on Google (after the 20:1 saying MSG is 'totally fine and safe').
