== Utterly confused == 

 I came to this page to learn about the limbic system - what it comprises and its function.  There's a handy list of what it includes, then immediately afterwards a section entitled 'Function' which opens with a structure (the hypothalamus) which wasn't listed before and mentions the basal ganglia, also not on the list.  Why are they not on the list? Is it debatable that they are included?  If so, say so.  If not, include them in the list!
