Applied Neuroscience, Inc. has developed a “Dynamic Link Library” or dll based on the statistics of NeuroGuide for approved industry developers to use in their products. The dll provides real-time normative database comparisons for absolute power, power ratios, relative power, coherence, phase delays and amplitude differences. Contact us at qeeg@appliedneuroscience.com for further details. An example of a potential use of instantaneous statistical analyses of the EEG is in EEG Biofeedback where the moment-to-moment comparison to a reference normal group of subjects is computed in real-time. The idea is to use Z scores as a threshold and to reinforce Z = 0, or Z = + or - 1, or whatever Z score depending on the judgment of the qualified biofeedback specialist. The use of Z scores for biofeedback reduces the complexity of biofeedback of voltages and ratios and coherence, etc. to a single metric, the metric of a Z score (i.e., Z = (mean-subject)/ st. dev). No longer wonder if coherence should increase or decrease or phase delay should shorten or lengthen or absolute power should increase or decrease for a given scalp location or a given age. Released in 2006 by BrainMaster Technologies, Inc., instantaneous Z score biofeedback using the
NeuroGuide dll. Contact www.appliedneuroscience.com.
