Imagining the future self through thought experiments.

Area of Science:

• Cognitive Neuroscience
• Neurobiology
• Psychology

Background:

• The capacity for counterfactual reasoning and future simulation is crucial for human cognition.
• Understanding the neural underpinnings of these abilities, such as imagining alternative pasts and futures, remains a challenge.

Purpose of the Study:

• To investigate the distinct roles of the frontopolar cortex (FPC) and anterior lateral prefrontal cortex (alPFC) in constructing suppositional scenarios.
• To elucidate the cognitive and neural mechanisms supporting counterfactual thinking and future planning.

Main Methods:

• The study proposes a functional dissociation between brain regions involved in evaluating past alternatives versus simulating future possibilities.
• Utilizes theoretical frameworks to link specific prefrontal cortex subregions to distinct aspects of hypothetical thought.

Main Results:

• The frontopolar cortex (FPC) is implicated in tracking and evaluating alternative past choices ('what might have done').
• The anterior lateral prefrontal cortex (alPFC) is suggested to compare future simulations ('what might do') and assess their potential rewards.

Conclusions:

• The FPC and alPFC work in concert to support the construction of suppositional scenarios, essential for complex decision-making.
• This research provides a framework for understanding the neural basis of hypothetical thinking and its role in cognition.
