List of NBT Biomarkers

The following biomarkers have been implemented in NBT. This is only a list of the major biomarker objects, check each biomarker to see details.

this list needs to be updated and offer link to a more detailed description of the individual biomarkers!

• Amplitudes in classical frequency bands (1-3 Hz, 3-7 Hz, 8-13 Hz, 16-36 Hz, 36-45 Hz)
• Hjorth's activity, mobility and complexity
• Barlow's frequency, amplitude and spectral purity index
• Wackermann's global field strength SIGMA, the global frequency PHI and a measure of spatial complexity OMEGA
• Spectral biomarkers based on the power spectrum (Peak frequency, Central frequency, individual alpha frequency etc.)
• Time-domain parameters

• Amplitude correlations
• Coherence
• Phase Locking Value
• Phase Lag Index
• Cross Phase Locking Value
• Synchronization Likelihood

• Amplitude distribution
• Detrended fluctuation analysis (DFA)
