Cognitive task execution (spoken word and image recognition) evokes precisely timed oscillatory episodes distributed across multiple cortical regions. Multichannel MEG recordings reveal dozens of engaged neural populations per recognition event, organized into an exponential involvement hierarchy. While this hierarchical organization is conserved across modalities, the preferentially activated cortical loci differ significantly between linguistic and visual processing.

摘要

Cognitive task execution (spoken word and image recognition) evokes precisely timed oscillatory episodes distributed across multiple cortical regions. Multichannel MEG recordings reveal dozens of engaged neural populations per recognition event, organized into an exponential involvement hierarchy. While this hierarchical organization is conserved across modalities, the preferentially activated cortical loci differ significantly between linguistic and visual processing.
