  • Patent number: 12178589
    Abstract: The present invention relates to a method for generating a sensorial stimulus using electroencephalographic data acquired from a subject, the method comprising the following steps: receiving electroencephalographic data comprising at least two electroencephalographic signals measured simultaneously from at least two electroencephalogram channels; calculating an alpha phase neuromarker on consecutive epochs of the electroencephalographic data, the alpha phase neuromarker being representative of at least the phase coherence between alpha waves recorded from the at least two electroencephalogram channels; and generating a sensorial stimulus representing alpha phase neuromarker using an output generator.

  • Patent number: 11116437
    Abstract: Disclosed is a method for scoring in real time neural signals of a subject with respect to a reference state characterized by k=1 . . . K reference covariance matrices, the method including the following steps: (i) obtaining neural signals from the subject; (ii) computing a covariance matrix of the neural signals; (iii) computing the Riemannian distances between the covariance matrix and k=1 . . . K reference covariance matrices; (iv) computing a continuous score s in real time based on at least one of the distances computed in step (iii). Also disclosed is a system and method for self-paced modulation or external modulation of neural activity of a subject.

  • Patent number: 11116440
    Abstract: Disclosed is a computer-implemented method for biofeedback training of a subject, the method including iteratively obtaining a series of biomarkers, each biomarker being representative of a bio-signal of the subject on a first time window; computing an intermediate threshold Thrintermediate(t) based on the series of biomarkers on a second time window, such that the intermediate threshold on the second time window could provide the subject with an expected reward ratio; computing a threshold Thr(t) as the weighted sum of the intermediate threshold Thrintermediate(t) and the threshold of the previous iteration Thr(t?1) and reporting in real-time a reward to the subject based on the difference between the biomarker and the computed threshold Thr(t), wherein at each iteration the time windows are moved forward in time. Also disclosed is a system for implementing the method.
