Name Description Delete
RSVP Target Detection Presents bursts of 12/s satellite image clips, some with an embedded target airplane image.
Auditory-Visual Attention Shift Young and older adults perform a visual-auditory cued attention shift paradigm.
Auditory Two-Choice Response Task with an Ignored Feature Difference Equally probable longer and shorter tones were so categorized by subjects using a choice manual response. Subjects were asked to ignore the slightly higher pitch of 10% of the tones.
Reward Two-Back CPT Visual two-back Continuous Performance Test with auditory feedback
Modified Sternberg Working Memory Task Visual letter memory task (recall black letters; ignore green)
Imagined Emotion Subjects listened to voice recordings that suggest an emotional feeling and ask subjects to imagine an emotional scenario or to recall an experience in which they have felt that emotion before.
Five-Box task A visual spatial selective attentional oddball task.
Ipsilateral ECoG 3D Reach Study Reaching in 3D space ipsilateral to ECoG recordings, ipsilesional to cortical lesions
Physical Exertion Recorded physical exertion (running on simulator) with pauses

What is HeadIT?

The Human Electrophysiology, Anatomic Data, and Integrated Tools (HeadIT) resource software allows researchers to store their raw EEG study data and (if they so choose) to enable named collaborator and/or public downloads.

The goal of HeadIT is to store and make available fully annotated raw data files for analysis, re-analysis, and meta-analysis. HeadIT uses EEG Study Schema (ESS) files to provide task, data collection, and subject metadata, including Hierarchical Event Descriptor (HED) tag descriptions of all identified experimental events.

How can I download the data?

You do not need a HeadIT account to download publicly available HeadIT studies. You must agree to the HeadIT Data Use Agreement and Terms of Use. You will need to create an account in order to enable your collaborators to share their private data with you.

Can I upload my data?

First create an account in the HeadIT system, then go to ‘Studies’ tab and click on the ‘New’ button.

Who developed HeadIT?

HeadIT is a project of the Swartz Center for Computational Neuroscience (SCCN) of the University of California, San Diego. Its development has been funded by U.S. National Institutes of Health grants R01-MH084819 (Makeig, Grethe PIs) and R01-NS047293 (Makeig PI).
