A computer-implemented method of processing data streams for synchronizing data streams sensed by a number of sensor devices (10, 20-40) with each other, the method comprising the following steps: recording, by a body-external, portable processing device comprising a time reference, the data streams ({d 1, d 2,..., d n}) sensed by the number of sensors (10, 20-40), at least one data stream thereof being representative of at least one physiologic signal of a patient sensed by a predetermined sensor device (10, 20-40) of the number of sensor devices, and generating, by the body-external, portable processing device, for each sensed data stream arrived at the body-external, portable device at least one time stamp (t) using the time reference, recording the at least one time stamp information (t), whereby the least one time stamp information (t) is associated with the respective at least one data stream ({d 1, d 2,..., d n}), each time stamp information (t) being representative of a point in time of associating the time stamp information (t) with the respective data stream ({d 1, d 2,..., d n}), associating a respective time shift information with each time stamp information (t), wherein the time shift information is representative of a delay (Δts) between a point in time of sensing the at least one signal by the predetermined respective sensor device (10, 20-40) and the point in time of associating the time stamp information (t) with the respective data stream ({d 1, d 2,..., d n}) representative of the at least one signal, and wherein the respective delay (Δts) is retrieved from a product specification database comprising information relating to the predetermined sensor devices (10; 20-40), further comprising transmitting each recorded data stream, and the respective time stamp information (t) to a database, and storing each data stream, the time stamp information, and the associated time shift information in the database, wherein the at least one physiologic signal represents an electrical activity of brain or nerves, and/or the at least one physiologic signal represents at least one value of a parameter, the parameter being one of pH, blood glucose, EMG, heart rate, skin conductivity, body movement, blood pressure, geo-local position, temperature, lightening level, concentrations of biomolecules, noise, and sound wherein the at least one sensor device is a neural implant. recording, by a body-external, portable processing device comprising a time reference, the data streams ({d 1, d 2,..., d n}) sensed by the number of sensors (10, 20-40), at least one data stream thereof being representative of at least one physiologic signal of a patient sensed by a predetermined sensor device (10, 20-40) of the number of sensor devices, and generating, by the body-external, portable processing device, for each sensed data stream arrived at the body-external, portable device at least one time stamp (t) using the time reference, recording the at least one time stamp information (t), whereby the least one time stamp information (t) is associated with the respective at least one data stream ({d 1, d 2,..., d n}), each time stamp information (t) being representative of a point in time of associating the time stamp information (t) with the respective data stream ({d 1, d 2,..., d n}), associating a respective time shift information with each time stamp information (t), wherein the time shift information is representative of a delay (Δts) between a point in time of sensing the at least one signal by the predetermined respective sensor device (10, 20-40) and the point in time of associating the time stamp information (t) with the respective data stream ({d 1, d 2,..., d n}) representative of the at least one signal, and wherein the respective delay (Δts) is retrieved from a product specification database comprising information relating to the predetermined sensor devices (10; 20-40), further comprising transmitting each recorded data stream, and the respective time stamp information (t) to a database, and storing each data stream, the time stamp information, and the associated time shift information in the database, wherein the at least one physiologic signal represents an electrical activity of brain or nerves, and/or the at least one physiologic signal represents at least one value of a parameter, the parameter being one of pH, blood glucose, EMG, heart rate, skin conductivity, body movement, blood pressure, geo-local position, temperature, lightening level, concentrations of biomolecules, noise, and sound wherein the at least one sensor device is a neural implant.
