Example Embodiment

[0111] figure 1 A first embodiment of the ear stimulation device 10 is shown, which has a first electrode 12, a second electrode 14, a control unit 16, a battery 17, and a speaker 18. The control unit 16 includes a memory 20, a processing unit 22, and a band pass filter 24. The ear stimulation device 10 is arranged at the ear 26 of the user 28 (see Figure 7 ), the largest part of the ear stimulation device 10 is arranged in the ear canal 30 of the user 28. The electrodes 12 and 14 are in contact with the skin of the ear canal 30.

[0112] The electrodes 12 and 14 measure the electrical activity signal 32 representing the EEG of the user 28 (see Figure 5 with 6 ). The electrical activity signal 32 is received by the control unit 16, which processes the electrical activity signal 32 by detecting (33) the presence of the slow oscillation 34 (see Figure 5 with 6 ). in figure 1 In the illustrated embodiment of the ear stimulation device 10, Figure 5 The method shown is used to...

Abstract

The present invention regards an in-ear stimulation device (10, 10'; 10a) comprising at least one in-ear sensor (12, 14), a control unit (16), and an output transducer (18). The in-ear stimulation device (10, 10'; 10a) is configured to be worn at or on an ear (26) of a human user (28) and at least partly in an ear canal (30) of the user (28). The at least one in-ear sensor (12, 14) is arranged and configured to measure electrical activity signals (32) indicative of an electroencephalogram (EEG) of a user (28) wearing the device (10, 10'; 10a). The control unit (16) is configured to receive the electrical activity signals (32) and to detect (33) a presence of a slow oscillation (34), which is in a frequency range between 0.5 Hz and 1 Hz, in the electrical activity signals (32). The control unit (16) is further configured to trigger, in response to detecting (33) the presence of a slow oscillation (34), a generation of at least one stimulus impulse (36). The output transducer (18) is configured to receive the at least one stimulus impulse (36) and to generate a corresponding output sound (38).

Description

technical field [0001] The present invention relates to an in-ear stimulation device comprising at least one in-ear sensor, a control unit and an output transducer and configured to measure electrical activity signals representing an electroencephalogram (EEG) of a user which are analyzed and used to generate a corresponding Or output sounds originating from or synchronized with slow oscillations detected in the electrical activity signal. Background technique [0002] Oscillations of brain activity reflect the synchronous activity that organizes information processing and communication in cortical networks of neurons in a state-dependent manner, see H.-V.V.Ngo, T. Martinetz, J. Born, and M. , "Auditory Closed-Loop Stimulation of the Sleep Slow Oscillation Enhances Memory", Neuron 78, 545-553 (2013) [Ngo et al. (2013)], as in G. Buzsáki and A. Draguhn "Neuronal oscillations in cortical networks", Science 304 1926-1929 (2004), and F. Varela, J.P. Lachaux, E. Rodriguez, and ...
