Contributions of occipital, parietal and parahippocampal cortex to encoding of object-location associations

We established a novel associative object-location memory paradigm, together with a parametric assessment of subsequent memory performance for spatial location which allows: (i) to determine if associative information is retrieved in a continuous or discontinuous manner during recognition and (ii) to investigate the relationship between activity during encoding and the resulting memory trace. Such correlations were observed in the occipital, parietal and the parahippocampal cortex, areas known to be involved in processing either objects and/or locations. The analysis of response functions revealed for the majority of areas involved in encoding a continuous relationship between brain activity during encoding and the confidence in a subsequent memory test.
