R&D Group 1 Specifying and updating of well-being and agency in society

This R&D group builds the premise of this project, and exposes in a data-driven way the 'well-being' and 'agency' that are valued in today's real society as targets to be given a real sense.

• R&D Plan 1-1 'Normative economics methods to narrow down welfare- and subjectivity-related words'
• R&D Plan 1-2 'Computational social science methods to identify key axes of well-being and agency'

R&D Group 2 Development and updating the system to discover pleasure and aspiration in society

In this R&D group, we develop "intervention" technologies that are essential to reflect 'well-being' and 'agency', which are objectively identified by R&D group 1, in the brain indicators of the subjective 'pleasure' and 'aspiration'.

• R&D Plan 2-1 'Supporting the Virtual Experience of Well-being and Initiative to Discover Pleasure and Aspiration'

R&D Group ３ Developing technology for inter-personal comparison of pleasure and aspiration by human brain indicators

Decomposing 'utility' into 'pleasure' and 'aspiration’ and maximizing the signal-to-noise ratio of their absolute indicators as much as possible, is key to the success of this project, and this R&D group that realizes this is essential for this project. It will also be an indispensable technology for monitoring and maintaining the effects of the pleasure and aspiration discovery system related to mobility, which will be developed in R&D group 2.

• R&D Plan 3-1 'Constructing neural indexes of pleasure and agency by MRI and their interpersonal comparisons'
• R&D Plan 3-2 'Neural circuit dynamics of pleasure and aspiration with human MEG'
• R&D Plan 3-3 'Task design to examine pleasure and aspiration and human single-unit recording'

R&D Group 4 Comprehensive understanding of utility representation in primate brain for interindividual comparison

This R&D group, which explains the validity of the brain indicators of utility and their comparison between individuals by ensuring causality through neural activity and its manipulation, is the scientific foundation that gives credibility to the findings of this project.

• R&D Plan 4-1 'Neural representations of utility and subjective value of reward'
• R&D Plan 4-2 'Interspecies and inter-individual comparisons of the neural representations of the subjective value of rewards between/within primates and rodents'

R&D Group 5 Comprehensive understanding subjective reward value representation in rodent brain for interindividual comparison

This R&D group, which clarifies the brain system that calculates the 'subjective value of rewards' as a surrogate for 'utility', provides the scientific foundation that gives unwavering credibility to the findings of this project.

• R&D Plan 5-1 'Understanding the neural systems of subjective value representation of rewards through comprehensive measurement of neuronal activity'
