From maps to new thoughts: can place-cell indexing generate novel cortical states?
Constructing novel states from experience underpins imagination and abstraction. The hippocampal formation is thought to contribute by capturing the relational structure of experiences, but it remains unclear how its abstract relational codes are eventually translated into cortical content representations. I highlight that hippocampal–cortical indexing may scaffold the generation of new states.

Online Now: The nativist–empiricist debate is broken
dlvr.it
The nativist–empiricist debate is broken
The nativist–empiricist debate has long organized cognitive science, framing cognitive mechanisms as either innate or learned. Recent advances in controlled rearing and scalable domain-general neural networks now allow this debate to be tested with unprecedented rigor, by raising newborn animals and deep neural networks under tightly matched developmental conditions. Strikingly, when pushed to this empirical limit, the debate does not resolve: the same developmental phenomena support both radical empiricism and radical nativism. We argue that this stalemate reflects a conceptual error. The debate conflates explanatory levels and ontological orientations, with nativists emphasizing stable symbolic structures and empiricists emphasizing the subsymbolic processes that produce those structures. We propose dissolving the dichotomy within a multilevel framework of cognitive development.

Screen capture of abstract of published article.

Title: A language network in the individualized functional connectomes of 1199 human brains doing arbitrary tasks

Abstract: A century and a half of neuroscience has yielded many divergent theories of the neurobiology of language. Two factors that likely contribute to this situation include (a) conceptual disagreement about language and its component processes, and (b) intrinsic inter-individual variability in the topography of language areas. Recent functional magnetic resonance imaging (fMRI) studies of small numbers of intensively scanned individuals have argued that a language-selective brain network emerges bottom-up from correlations (individualized functional connectomics, iFC) in task-free (e.g., rest) or task-regressed activation timecourses. Here we tested this hypothesis at scale and evaluated its practical utility for task-agnostic language localization: we apply iFC separately to each of 1,957 (fMRI) scanning sessions (1...
