| Outline of Final Research Achievements |
Prefrontal cortex and inferior temporal cortex are two important areas, involved in memory recall formation. However, the functional connectivity and its multi synaptic projection relays between these two areas have not been well identified. In this study, we trained macaque monkeys to perform recency test, a test which monkeys are asked to study many serially shown pictures. Then, monkeys are asked to choose one recently seen picture from two shown pictures. We performed functional MRI analysis when monkeys are performing these tasks in MRI. We found that area 9 in prefrontal cortex and area TE in inferior temporal cortex has functional connectivity and reported this result in a scientific journal.
