The History


First study of timing impairments in concussion, funded by the James S. McDonnell Foundation, conducted in a collaboration between University of California, San Francisco, University of California, Berkeley, and Weill Cornell Medical College. The study was led by Dr. Jam Ghajar, Principal Investigator.


In 2006, Dr. Jam Ghajar and Dr. Minah Suh publish an investigation into predictive eye tracking and mild traumatic brain injury (concussion) for Brain Trauma Foundation (BTF).

Two years later, Dr. Ghajar and Dr. Richard Ivry publish a new theory of Predictive Brain State – a mechanism for attention that is affected by concussion.


SyncThink founded to develop mobile eye tracking technology and analytics in support of Brain Trauma Foundation (BTF) research with Department of Defense.



First prototype headset developed.

Dr. Ghajar, Dr. Jun Maruta, and BTF confirm link between predictive eye tracking impairment and MRI white matter injury among concussion patients.



SyncThink develops head-mounted eye tracking platform using clam shell design.

Brain Trauma Foundation awarded $25M grant to pursue largest-ever ocular-motor clinical study. 


SyncThink is awarded Department of Defense grant to develop lightweight platform for field use.


SyncThink integrates eye tracking assessments onto emerging VR platform, called EYE-SYNC.

Brain Trauma Foundation publishes link between predictive eye tracking and ADHD on-and-off medication.


Stanford adopts and develops concussion protocol around EYE-SYNC for all student athletes.


SyncThink awarded FDA clearance for EYE-SYNC, and its 10th patent.

EYE-SYNC deployed in research study on the sidelines across Pac-12 schools – Utah, Stanford, USC, Oregon State – to monitor recovery rates after injury, as well as by clinicians at Stanford University Hospital, Mass General Hospital, and Walter Reed.


SyncThink upgrades hardware version 2.0 to Gear VR with built-in eye trackers.

SyncThink works with Shire to apply SyncThink technology to clinical models.
