Implication

Randomized trial examines brain mechanisms of effort valuation in cognitive and physical tasks, indicating shared valuation networks and unique processing roles.

Key Points

This research aims to understand how subjective valuations of effort costs are processed in the brain across different task domains.
Utilized computational modelling and functional magnetic resonance imaging (fMRI) to assess brain activity.
Participants engaged in tasks that manipulated cognitive and physical effort while indicating their preferences for different reward options.
Identified brain areas involved in effort cost evaluation and reward processing.
A common network for valuation was found, including the dorsomedial prefrontal cortex and anterior insula, correlated with effort and reward parameters.
Activity in these areas showed negative correlation with reward and positive with effort.
The amygdala had a specific role in processing rewards from cognitive effort.
