Intheon Role: Tim Mullen co-led development of the Glass Brain with Adam Gazzaley (Director, UCSF Neuroscape Lab).

Intheon Role: Intheon is the primary curator of HED standard. Open source HED tools are developed jointly by Prof. Kay Robbins (Univ. Texas, San Antonio) and Intheon.
EEG Study Schema (ESS) makes it easier for researcher in the field of EEG/BCI to package, share and automatize the analysis workflow of their study data.You can think of ESS as a “shipping container” for your EEG study data.• An XML-based specification
• Holds all the information necessary to analyze an EEG study: task and paradigm description, recording parameters, sensor locations, gender, handedness, age and group associations of subjects.
• Contains a table of HED tags for event codes.
• Both human- and machine-readable. The XML file may be readily formatted into a readable description of the EEG study.
Intheon Role: Intheon is the curator of ESS standard and the developer of open source ESS tools. The standardized EEG processing pipeline (PREP) is developed jointly by Prof. Kay Robbins (UTSA) and Intheon.
Intheon is a founding member of the BigEEG Consortium™ whose goal is to promote and facilitate large-scale analysis (e.g. meta-study) of EEG and other data modalities related to real-world neuroimaging. This is implemented through developing open standards and tools for event tagging and meta-data encapsulation, along with providing publicly available standardized data and workflows.Currently, there are two major standards being promoted by the consortium:
• Hierarchical Event Descriptor (HED) tags. For describing experimental and real-world events. See www.hedtags.org
• EEG Experiment Schema (ESS). For encapsulating EEG study meta-data. See www.eegstudy.org
For a list of studies currently available in ESS format please visit: www.studycatalog.org
In addition to these, we have released a standard EEG pre-processing toolbox for noisy channel detection and robust referencing, called PREP: http://vislab.github.io/EEG-Clean-Tools/
