- description: |
- The basal ganglia are a group of interconnected subcortical nuclei that plays a key role in multiple motor and cognitive processes, in a close interplay with several cortical regions.
- Two conflicting theories postulate that the basal ganglia pathways can either foster or suppress the cortico-striatal output or, alternatively, they can stabilise or destabilise the cortico-striatal circuit dynamics.
- These different approaches significantly impact the understanding of observable behaviours and cognitive processes in healthy, as well as clinical populations.
- We investigated the predictions of these models in healthy participants (N=28), using dynamic causal modelling of fMRI BOLD activity to estimate time- and context-dependent changes in the indirect pathway effective connectivity, in association with repetitions or changes of choice selections.
- We used two multi-option tasks that required the participants to adapt to uncontrollable environmental changes, by performing sequential choice selections, with and without value-based feedbacks.
- We found that, irrespective of the task, the trials that were characterised by changes in choice selections (switch trials) were associated with a neural response that mostly overlapped with a network commonly described for the encoding of uncertainty.
- More interestingly, dynamic causal modelling and family-wise model comparison identified with high likelihood a directed causal relation from the external to the internal part of the globus pallidus (i.e. the short indirect pathway in the basal ganglia), in association with the switch trials.
- This finding supports the hypothesis that the short indirect pathway in the basal ganglia drives instability in the network dynamics, resulting in changes in choice selection.
