Associative Learning Beyond the Medial Temporal Lobe: Many Actors on the Memory Stage

Giulio Pergola, Boris Suchan
2013 Frontiers in Behavioral Neuroscience  
Notice that sensory information is only partly integrated at the level of the perirhinal, parahippocampal, and entorhinal cortices.  ...  We propose that these networks contribute differently to recognition memory and recall, and also that the memory stage of their contribution shows specificity to encoding or retrieval in recall tasks.  ...  Notice the triangular connections involving the medial temporal lobe, the midline thalamus and the orbitofrontal, and ventromedial cortex.  ...
