The spatiotemporal dynamics of semantic integration in the human brain [article]

Elliot Murphy, Kiefer J Forseth, Cristian Donos, Patrick S Rollo, Nitin Tandon
2022 bioRxiv   pre-print
Language depends critically on the integration of lexical information to derive semantic concepts. The neurobiology of this fundamental aspect of human cognition remains mostly unknown.  ...  Early processing windows implicated IFS in all aspects of semantics, and in later windows sub-portions of IFS exposed a clearer functional tessellation with some remaining overlap.  ...  Acknowledgements We express our gratitude to all the patients who participated in this study; the neurologists at the Texas Comprehensive Epilepsy Program who participated in the care of these patients  ...
