@ws1022 you are correct. Please see the reasoning in this discussion (Warning its pretty long):
Basics of it are: Kaplan lists thalamus and hypothalamus separately from the limbic system as in the card currently. Thalamus (for example) has a more extensive role beyond its limbic contributions and only certain components of the thalamus are involved in the “classical” limbic system. The concern was by saying the forebrain contains the limbic system (without separately mentioning the thalamus and hypothalamus) are we potentially suggesting that the forebrain only contains the elements of the anatomical structures and their related functions specifically associated with the limbic system rather than what we intend: the entire hypothalamus, thalamus and their functions. Ultimately decided it was safest to side with how Kaplan lists them.
Lmk what your thoughts are.
