Research indicates that significant damage to primates’ medial frontal cortex (MFC) can impede action initiation when anticipating rewards. However, the specific roles within the MFC related to self-g...

The neuronal connections between the midcingulate cortex (MCC) and the dorsolateral prefrontal cortex (dlPFC) are associated with multiple cognitive functions, including rapid and long-term adaptive p...

The brain uses different valuation schemes across contexts. Elston and Wallis show this is supported by hippocampal encoding of context that is broadcast to prefrontal value subcircuits via theta sync...

How the prefrontal hemispheres coordinate to adapt to spatial working memory (WM) demands remains an open question. Recently, two models have been proposed: A specialized model, where each hemisphere governs contralateral behavior, and a redundant model, where both hemispheres equally guide behavior in the full visual space. To explore these alternatives, we analyzed simultaneous bilateral prefrontal cortex recordings from three macaque monkeys performing a visuo-spatial WM task. Each hemisphere represented targets across the full visual field and equally predicted behavioral imprecisions. Furthermore, memory errors were weakly correlated between hemispheres, suggesting that redundant, weakly coupled prefrontal hemispheres support spatial WM. Attractor model simulations showed that the hemispheric redundancy improved precision in simple tasks, whereas weak inter-hemispheric coupling allowed for specialized hemispheres in complex tasks. This interhemispheric architecture reconciles previous findings thought to support distinct models into a unified architecture, providing a versatile interhemispheric architecture that adapts to varying cognitive demands. ### Competing Interest Statement The authors have declared no competing interest.
