Flexible Reconfigurations of Brain Networks During Decisions With Predefined Versus Self-Generated Options.

ABSTRACT: How do large-scale brain networks dynamically reorganize to support different types of decision-making with distinct yet overlapping cognitive demands? While we often make decisions by evaluating and choosing from a set of externally defined choice options, we can also generate options internally from our existing knowledge store. Such flexibility suggests the ability for decision-related brain networks to reconfigure in response to the need to recruit sensory processing and semantic retrieval modules to evaluate externally and internally generated options, respectively. Here we sought to test this hypothesis by applying graph-theoretic tools to functional neuroimaging data obtained for (i) decisions with externally provided options (external-menu choices/EMC); (ii) decisions with self-gen
