An interplay of fusiform gyrus and hippocampus enables prototype- and exemplar-based category learning.

摘要: The aim of the present study was to examine contributions different brain structures prototype- and exemplar-based category learning using functional magnetic resonance imaging (fMRI). Twenty-eight subjects performed a categorization task in which they had assign prototypes exceptions two families. This test procedure usually produces curves for prototype exception stimuli. Our behavioral data replicated these previous findings by showing an initially superior performance typical stimuli switch from prototype-based later phases. Since varied, we divided participants into learners non-learners. Analysis revealed that interaction group (learners vs. non-learners) block (Block 5 Block 1) yielded activation left fusiform gyrus processing prototypes, right hippocampus after categories. Thus, successful is associated with activations complementary neural substrates constitute object-based processes ventral visual stream their unique-cue representations, possibly based on sparse coding within hippocampus.
