摘要:
A method for controlling a stimulation signal (208) for brain stimulation comprises: transmitting (302) a trigger signal for triggering a stimulation generator (120) to output a high frequency synchronization signal (202) exhibiting periodical modifications (204); receiving (304) a measurement signal representing brain activity comprising neural oscillations and a response to the high frequency synchronization signal (202); determining (306) adjustment of a phase of the stimulation signal (208) based on a phase difference between the neural oscillations and the modifications (204) of the high frequency synchronization signal (202); and transmitting (308) a phase information signal for providing information of an adjusted phase of the stimulation signal (208) to be used by the stimulation generator (120).

There is a method for emotion-triggered capturing of audio and/or image data by an audio and/or image capturing device (202). The method includes receiving (402) and analyzing (404) a time-sequential set of data including first physiological data representing a first physiological parameter on a first person (302), a second physiological data representing a second physiological parameter on a second person (304), and voice audio data including a voice of at least one of the first (302) and the second (304) person, to determine whether a simultaneous change of emotional state of a first person (302) and a second person (304) occurs and transmitting (406) a trigger signal to said capturing device (202). There is also a corresponding apparatus (100) and a system (200) comprising the apparatus (100).
