This growth necessitates fresh conceptual paradigms for comparing neural circuits and activity patterns. Here, we take a systems neuroscience approach to early neural evolution, emphasizing the importance of considering nervous systems as multiply modulated, continuous dynamical systems. We argue that endogenous neural activity likely arose early in evolution to organize behaviors and internal states at the organismal level. This connects to a rich literature on the physiology of endogenous activity in small neural circuits: a field that has built links between data and dynamical systems models. Such models offer mechanistic insight and have robust predictive power. Using these tools, we suggest that the emergence of intrinsically active neurons and periodic dynamics played a critical role in the ascendancy of nervous systems and that dynamical systems present an appealing framework for comparing across species.</p></div>","PeriodicalId":56191,"journal":{"name":"Current Opinion in Behavioral Sciences","volume":null,"pages":null},"PeriodicalIF":4.9,"publicationDate":"2024-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141962546","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Functional connectivity between brain networks associated with cognitive control (e.g. dorsal attention, frontoparietal, and ventral attention networks) and mind wandering (e.g. default mode network) play an important role in cognitive flexibility. The antagonistic relationship between these and other attentional networks mediate task switching and task engagement.

Functional magnetic resonance imaging (fMRI) studies suggest that across disorders, brain activity is altered during set-shifting and probabilistic reversal learning tasks in regions of large-scale cognitive and attention networks, including the frontoparietal, cingulo-opercular/action-mode, and default-mode networks.
