Hi Kora , it seems confusing to me too , do you mean to check first what symptoms could the liver show if the problem was (let’s say ) an old brain theme , then we’ll  check first how the stress phase looks like according to the symptoms compass:

Example :
Liver Parenchyma/BS

If there was a functional change / it’ll be enhancement ( here we’ll ask ourselves how an enhancement of function will look like ? 

We go on on all symptoms and then 
We check if we can find the liver in other brain layers and so on ? 

Is it this what’s needed in the task ? Plz help Kora :)
