1 Background to psychobiology - Assets
... An important group of forebrain structures were defined in the 1930s and their key role was assumed to reflect motivational and emotional processing (Papez, 1937). MacLean (1949) provided further modifications to what was then called ‘Papez circuit’, and we now refer to it as the limbic (‘ringshaped’) ...
