EyeLink integration with ANT Neuro EEG Devices.
ANT Neuro provide cutting-edge solutions for neuroscience and neurodiagnostics. Integration between EyeLink systems and ANT Neuro devices is very straightforward and is achieved through standard TTL signaling via a parallel port (or USB2TTL8 device) on the stimulus display PC. The only other component required is a Trigger Cable (supplied by ANT Neuro). TTL signals can be sent from the stimulus display PC directly to the ANT Neuro device to mark critical trial events (such as stimulus onset). TTLs can also be used to start and stop recording on the ANT Neuro device.
EyeLink and ANT Neuro Integration Detail
- During task performance, the stimulus presentation software (e.g., Experiment Builder, PsychoPy, E-Prime, Presentation, PsychToolBox, etc.) simultaneously sends TTLs signals to the ANT Neuro device via a parallel port / trigger cable and messages to the EyeLink Host PC via the ethernet link.
- The TTLs / Messages mark key trial events (such as stimulus onset / participant response etc), allowing the two data streams to be synchronized at the analysis stage.
- If neither the Display PC or Host PC has a parallel port, then we can provide a USB to TTL device with excellent timing properties. Please contact sales@sr-research.com for details.
Experiment Builder and ANT Neuro Integration
Our stimulus presentation software, Experiment Builder, has a Biometric TTL Node that can be configured to send the relevant TTL signals at appropriate points during the task.
