Performance Monitoring Local Field Potentials in the Medial Frontal Cortex of Primates: Supplementary Eye Field

Erik E. Emeric, Melanie Leslie, Pierre Pouget, Jeffrey D. Schall
2010 Journal of Neurophysiology  
We describe intracranial local field potentials (LFPs) recorded in the supplementary eye field (SEF) of macaque monkeys performing a saccade countermanding task.  ...  This negative polarity did not appear in unrewarded correct trials. Variations of response time with trial history were not related to any features of the LFP.  ...  Thus in general, intracranial LFPs recorded in macaque SEF as well as in ACC appear to correspond to ERPs recorded from human participants.  ...

2015 Proceedings of the National Academy of Sciences of the United States of America  
In contrast, direct intracranial cortical recordings offer a unique opportunity to acquire neural signals with an unprecedented combination of temporal and spatial resolution.  ...  Moreover, when novel strings of articulatory gestures must be produced in response to nonword stimuli, neural activity is enhanced in Broca's area, but not in motor cortex.  ...  All peripheral signals and responses were recorded together with intracranial EEG signals to ensure proper synchronization (sampled at 1,000 Hz using a clinical 128-channel Harmonie system from Stellate  ...
