Quantifying auditory event-related responses in multichannel human intracranial recordings
2010
Frontiers in Computational Neuroscience
Preserved Fulltext
to determine the statistical signifi cance of event-related responses in intracranial recordings. We adapted this quantitative approach for auditory ECoG studies conducted at our epilepsy center. ...
Multichannel intracranial recordings are used increasingly to study the functional organization of human cortex. ...
We will focus on three types of cortical auditory event-related activity in ECoG signals: evoked responses; spectral (induced) responses; and multichannel event-related connectivity. ...

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. ...
