Which datasets are used in the documentation and where are they used?

The FieldTrip website and ftp server include a variety of datasets. Some of these are used in the tutorials, while others are used in example MATLAB scripts. All of these datasets were recorded from humans, unless otherwise specified.

Below you will find a brief description of each dataset. The name given to each dataset is meant to provide an instant understanding of 'how the data was collected', 'the cognitive domain to which the data relates', and if it applies, 'what specific topic within the domain'. For example: 'MEG-language-semantics' will tell you that the data was collected in an MEG scanner, relates to research in the language domain, and specifically to semantics. Links to the FieldTrip ftp server are provided so that you can download the dataset of interest.

Alternative EEG and MEG datasets

The Human Connectome Project contains MEG data from close to 100 subjects, which were scanned on the 248-channel 4D/BTi MEG system at SLU, St Louis. The MEG data includes resting-state and three different experimental tasks, and anatomical, functional (1200 subjects, resting and task) and associated behavioral and demographic data is available. See also doi: 10.1016/j.neuroimage.2013.05.056 and doi: 10.1016/j.neuroimage.2015.04.046.

The Cambridge Centre for Ageing and Neuroscience released raw data from the Cam-CAN cohort, including MEG, MRI and cognitive data from approximately 650 males and females uniformly distributed from 18 to 88 years of age. The MEG data (in FIF format) include 3 runs of 1) rest, 2) a sensorimotor task, and 3) a passive sensory task (with separate visual and auditory stimuli).

The Open MEG Archive (OMEGA) is a collaborative effort by the McConnell Brain Imaging Centre and the Université de Montréal. It consists of a open repository with MEG data. This continuously expanding repository also contains anatomical MRI volumes, demographic and questionnaire information, and eventually will feature other forms of electrophysiological data (e.g. EEG, field, and cell recordings). See also doi: 10.1016/j.neuroimage.2015.04.028

The Kymata Atlas also shares datasets with electromagnetic measurements of the human cortex done at the MRC Cognition and Brain Sciences Unit of Cambridge University. The shared data comprises (averaged) EEG and MEG sensor data, and current density reconstructions. The participants are healthy human adults listening to the radio and/or watching films.

Wakeman and Henson have shared A multi-subject, multi-modal human neuroimaging dataset that includes raw MEG and EEG data from 16 subjects. This data also forms the basis for the SPM documentation.

Other MEG data analysis toolboxes (MNE, BrainStorm) also share tutorial datasets.

Alternative ECoG datasets

Kahana and Rizutto have released EGoG data from 149 subjects collected during Phase I of the Restoring Active Memory (RAM) project. The dataset includes information from 700 sessions, and for every patient, intracranial recording files from 100 to 200 electrode channels, neuro-anatomical information indicating the location of each electrode, precise records of patient behavior and the experimental design documents.

Alternative LFP and spike datasets

A collection of intracranial animal datasets is shared on the Collaborative Research in Computational Neuroscience data sharing website.
