Oxford Events, the new replacement for OxTalks, will launch on 16th March. From now until the launch of Oxford Events, new events cannot be published or edited on OxTalks while all existing records are migrated to the new platform. The existing OxTalks site will remain available to view during this period.
From 16th, Oxford Events will launch on a new website: events.ox.ac.uk, and event submissions will resume. You will need a Halo login to submit events. Full details are available on the Staff Gateway.
Modular organization, the division of the cerebral cortex into functionally distinct subregions, is well established in the primate sensorimotor cortex, but debated in the cognitive association cortex, including the lateral prefrontal cortex (PFC). So far, single-unit recordings have not confirmed the prefrontal rostro-caudal gradients observed in neuroimaging and neuroanatomical experiments. To bridge these microscale and macroscale perspectives, we obtained microelectrode recordings with exceptional spatial coverage from the PFC of monkeys engaged in a working memory task. Neighboring electrodes shared task-related neural dynamics that were stable across recording sessions and formed spatially continuous, mesoscale clusters with distinct local and long-range fronto-parietal connectivity. Spiking activity was cluster-specific and related to either the encoding, maintenance or decoding of working memory content. Our findings support parcellation of the PFC by cognitive control operations rather than by processed information, indicating that modularity is a fundamental architectural principle across the primate cortex.
