| Outline of Final Research Achievements |
When deciding between multiple options, our brain estimates their values and choose the most desirable one. A lot of studies show that areas in the prefrontal cortex (PFC) play different but essential roles for value calculation and comparison. However, few studies directly examined how the value information is generated in the PFC. Here, I developed ECoG electrodes to implant in the wide-ranging areas of the macaque PFC and trained a monkey, who was implanted the ECoG electrodes on the PFC subareas, to perform the context dependent value learning task. I recorded the ECoG signal while the monkey performed the task and tried to decode the reward value from the ECoG signal. However, I could not decode the value from the ECoG signal. Finally, I perfused and fixed the monkey’s brain and checked the condition of the implanted ECoG electrode. I found that to keep the good condition of the electrodes is important for ECoG signal recording and the decoding information from the ECoG signal.
