2011 NeuroImage  
To determine whether such causal interactions occur at high gamma frequencies and to investigate their functional significance, we used event-related causality (ERC) analysis to estimate the dynamics,  ...  directionality, and magnitude of event-related causal interactions using subdural electrocorticography (ECoG) recorded during two word production tasks: picture naming and auditory word repetition.  ...  Frederick Lenz for his neurosurgical care of the patient; Dr. Krauss for his neurological care of the patient; Wai-tat Peter Poon, Lei Hao, and Jeffrey M.  ...

Quantifying auditory event-related responses in multichannel human intracranial recordings

2010 Frontiers in Computational Neuroscience  
Intracranial recordings of event-related activity, or electrocorticography (ECoG), are based on high density electrode arrays implanted directly over cortex, combining good temporal and spatial resolution  ...  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.  ...  Event-related causality (ERC) is a new method for measuring event-related changes in causal interactions between multi-electrode recording sites, to estimate the effective connectivity of cortical networks  ...
