The original dataset (after defacing the imaging data with ft_defacevolume) and the processed results are available for download from here. The neural data were recorded in the context of an experiment that required the patient to press a button with the right hand when hearing a target tone.

The data set includes a pre-implant T1-weighted MRI, a post-implant CT, a post-implant T1-weighted MRI, and neural recordings from 96 ECoG and 56 SEEG electrodes that were implanted as part of the preparation for the epilepsy surgery. The Office for the Protection of Human Subjects of the University of California, Berkeley, approved the study and the subject gave informed consent. The example iEEG data set was acquired at the Medical Center of the University of California, Irvine. Please cite that paper when you use the methods described here. The information on this page originates from the human intracranial data analysis protocol described in Stolk, Griffin et al., Integrated analysis of anatomical and electrophysiological human intracranial data, Nature Protocols, 2018. If you are getting started with FieldTrip, download the most recent version from its homepage or GitHub and set up your MATLAB path. You will need the iEEG data of SubjectUCI29, which can be obtained from here. Many other supported analyses such as event-related potential analysis, connectivity analysis, and statistical analysis have been described in detail elsewhere (Oostenveld et al., 2011 Maris & Oostenveld, 2007 Bastos & Schoffelen, 2016). The tutorial demonstrates the analysis of task-related high-frequency-band activity (~70 to 150 Hz), a prominent neural signature in intracranial data that has been associated with neuron population level firing rate. The example iEEG dataset used in this tutorial is not representative for all the datasets obtained in the field but it is meant to serve as a platform for thinking and dealing with the challenges associated with analyzing this type of data.

Some medical institutes use photography or X-ray (e.g., see Analysis of monkey ECoG recordings) for including anatomy in the analysis of the functional recordings, whilst others use CT (3D image from a series of X-rays) and/or MR, or combinations thereof.

#Intracranial eeg and human brain mapping how to#
This tutorial illustrates how to deal with the multitude of raw anatomical and electrophysiological data files in order to get to integrated neural observations.īefore we start, it is important to emphasize that human iEEG datasets are solely acquired for clinical purposes and come in different shapes and sizes. In humans, the most common implementation of iEEG is when non-invasive techniques such as scalp-EEG and MRI do not provide sufficient information to guide surgery in medication refractory epilepsy patients. These recordings are known for known for their high spatiotemporal precision. Intracranial EEG (iEEG) allows simultaneous recordings from tens to hundreds of electrodes placed directly on the neocortex (electrocorticography, ECoG), or intracortically (stereoelectroencephalography, SEEG).
