PRANA - Polygraphic Recording Analyzer

The PRANA® software for biosignal processing has powerful computing capabilities and modularity allowing multiple software plug-ins to be executed efficiently.

Various software plug-ins for general and specific purposes are already available:

• the artifact detection plug-in
• the waveform detection plug-in
• the sleep spindle detection plug-in
• the rapid eye-movement detection plug-in
• the sleep K-complex detection plug-in*
• the respiratory event detection plug-in*

All the software plug-ins can be executed in a single run by using the software plug-in launcher. Additional plug-ins can easily be implemented using the software developer kit.

Artifact detection

The software artifact detection plug-in allows for automatic signal decontamination by localizing, marking and removing traces containing recording artefacts.

With its graphical interface, this user-friendly and flexible software plug-in features:

• single-run multiple artifact detectors,
• detector adjustable settings (time resolution and interval, channel selection, frequency filtering, signal feature selection, threshold type),
• default detector settings for most common artifacts (movement, electrode detachment, over-flow, flat-line, power-line, muscular and ocular activity, etc.),
• saving and loading detector settings,
• user-defined detectors using customised settings,
• detection supervision using adjustable artifact properties.

Thanks to the software artifact detection plug-in and to its integrated artifact removal procedure, the PRANA® software offers a mean to undertake high-quality signal analyses.

Waveform detection

The software waveform detection plug-in allows for automatic waveform detection by analysing signals, localising waveforms and marking events from the corresponding traces.

With its graphical interface, this user-friendly and flexible software plug-in features:

• single-run multiple waveform detectors,
• detector adjustable settings (time resolution and interval, channel selection, frequency filtering, signal feature selection, threshold type),
• default detector settings for most common waveforms (delta, theta, alpha, beta and gamma bursts),
• saving and loading detector settings,
• user-defined detectors using customised settings,
• detection supervision using adjustable waveform properties.

Thanks to the software waveform detection plug-in, the PRANA® software allows analysing biosignal by detecting events and measuring event densities.

Sleep spindle detection

The software sleep spindle detection plug-in allows for the automatic detection of events such as sleep spindles from any EEG recordings.

With its graphical interface, this user-friendly and flexible software plug-in features:

• single-run analysis of multiple channels,
• adjustable settings (channel selection, frequency filtering, events duration and interval, threshold),
• default detector settings for human sleep spindles,
• user-defined detection using customised settings,
• detection supervision using adjustable events properties.

Thanks to the software sleep spindle detection plug-in, the PRANA® software allows the detection sleep grapho-elements and measuring event densities from any conventional PSG recording.

Rapid eye-movement detection

The software rapid eye-movement detection plug-in allows for the automatic detection of events such as rapid eye-movements from any conventional EOG recordings.

With its graphical interface, this user-friendly and flexible software plug-in features:

• single-run analysis of multiple channels,
• adjustable settings (channel selection, frequency filtering, events duration and interval, amplitude and slope thresholds),
• default detector settings for human rapid eye-movements,
• user-defined detection using customised settings,
• detection supervision using adjustable events properties.

Thanks to the software rapid eye-movement detection plug-in, the PRANA® software allows the detection sleep grapho-elements and measurement of event densities from any conventional PSG recording.

Respiratory event detection*

The software respiratory event detection plug-in allows for the automatic detection of respiratory events (apnea, hypopnea, blood oxygen desaturation, snoring and body position) from conventional PSG recordings.

With its graphical interface, this user-friendly and flexible software plug-in features:

• single-run analysis of multiple events,
• adjustable settings (channel selection),
• default detector settings for human respiration,
• user-defined detection using customised settings,

Thanks to the software respiratory event detection plug-in, the PRANA® software facilitates the diagnosis of sleep breathing disorders by detecting respiratory events from conventional breathing recordings.

*Compatible only with specific recording settings.
