Ah, another "bad medical thing found! .... in mice".

It's almost as if research is done on mice on purpose. Of course you're going to see new discoveries, positive or negative, come out of studies involving the most widely used test subject on the planet.

Huh, I'd have said this idea was already well-established. I'm curious how this finding is different than the existing evidence that bodily sensations can influence emotions. I mean, I can't be the only one who feels anxious when I've had too many cups of coffee or ate something funny

And in a lot of cases, these headlines talk about some amazing discovery, only for it to not actually apply to humans.

It was already know that the peptide fragment CCK-4 reliably causes sever panic panic attack when administered in doses of 50 μg. And CCK4 is fragment of an hormone produced by the duodenum.

If the small intestine can trigger a panic attack, it's not that surprising that other organs can also create anxiety.

Does this generality apply to this specific situation? Do you even know?

Does the generic 'yah but it sez in mouse' really add anything to the conversation?

I'd love to hear from an expert on the subject, thats why I'm on HN.

People with anxiety could have told you this :)

Exactly. I have anxiety and panic attacks. When my heart beats faster for whatever reason, it triggers anxiety and in more extreme cases, panic attack. It's kind of obvious, really.
