The part of the brain that performs that function is the hypothalamus.
Honestly, this is supposed to be your opinion, but I will give you mine. I think there should by far be a quality standard, that they should always provide good quality things. It all just depends on what kind of standard they are talking about or what the question is referring to. If there are experiments going on, there should definitely be a certain standard of safety and ensure that the person would come out alive. I hope that this could help a bit, and I apologize if this was not the type of standard in which you were looking for. If you need further help, you can send a DM my way and I will respond when I get the chance. Have an amazing day!
