| Outline of Final Research Achievements |
I analyzed the neural mechanisms underlying cognitive memory from two view-points: 1) First, we investigated how the whole-brain neural network operates through the exchange of specific information that originates from local microcircuits and single neurons. Particularly, we compared microcircuit operations across areas in the monkey temporal cortex and found a novel principle for cortical computation on object processing, in which precursor codes for object features are constructed in a lower-order area before prevalence in a higher-order area. 2) Second, we investigated causal impacts of reversible silencing of the cortical sites that such a whole-brain network search has successfully identified. Particularly, we discovered a center of metamemory for temporally remote events in the prefrontal area 9. These studies provided an outstanding development in understanding of causal neural origin of high-level cognition such as metamemory.
