Cold beer produced strange thoughts here (8)
I believe the answer is:
cerebrum
'thoughts here' is the definition.
(part of the brain)
'cold beer produced strange' is the wordplay.
'cold' becomes 'c' (eg on taps).
'produced' indicates an anagram.
'strange' becomes 'rum' (I've seen this before).
'beer' with letters rearranged gives 'ereb'.
'c'+'ereb'+'rum'='CEREBRUM'
(Other definitions for cerebrum that I've seen before include "Principal part of brain in front of skull" , "Principle part of brain, in front of skull" , "One thinks" , "Main part of the brain" , "not a whole loaf?" .)
