I have previously described a test for glutamate hypofunction, which usually implies schizophrenia. (If you're following my case, it's because I have a plain deficiency, which is different.)

Now my serine supplement has run out for the night and I've slipped back into glutamate-negative mode, so I've filmed myself taking the test.

The test is: put your fingers on the tops of your cheekbones and find the zygomaticus minor muscles. Flex that muscle and everything above it in the face. Loosen everything beneath it, and let some soda into your mouth from a glass or a fingered straw. If you experience involuntary facial movements, this is because you have glutamate hypofunction, and likely schizophrenia.

Why does this work? It goes back to schizophrenic "reduced affect display". I'd take a moment to clarify that schizophrenic reduced affect display is actually "strict affect": the inability to move the top half and bottom half of the face at once. The facial exercise I describe forces facial expression into the top half of the face, which leaves the bottom half susceptible to "carbonation grimace".

Carbonation grimace "at rest", without facial exercises, is different. That would imply you have Florian syndrome.
