1. A computer-implemented method for controlling a brain stimulation system, the brain stimulation system comprising:
an implantable sensor device which is adapted for being placed into a brain cavity of a patient,
a neural stimulation device which is adapted for being placed into the brain cavity, and for applying stimulation signals to the patient, the neural stimulation device being a neural implant,
a body-external, portable processing unit, the method comprising the following steps:
receiving, by the body-external, portable processing unit, a number of data streams, at least one data stream thereof being representative of at least one physiologic signal of a patient sensed by the sensor device, the physiologic signal representing an electrical brain activity,
generating at least one time stamp information at the body-external, portable processing unit, the at least one time stamp information being based on a time reference comprised by the body-external, portable processing unit, each time stamp information being associated with a respective data stream of the number of data streams,
each time stamp information being representative of the point in time of associating the time stamp information with the respective data stream, recording, in a body-external temporal storage device, the at least one data stream and at least one time stamp information associated thereto, and
associating a respective time shift information with each time stamp information, and recording the time shift information associated with the time stamp information in the body-external temporal storage device, the time shift information being at least partially based on the corresponding sensor device associated with the corresponding data stream, and representative of a delay between a point in time of sensing the at least one signal by the sensor device and the point in time of associating the time stamp information with the data stream representative of the at least one signal, and
updating therapeutic parameters of the neural implant based on the at least one data stream thus temporally aligned, and sending the therapeutic parameters to the stimulation device,
wherein the time shift information is additionally representative of a delay between the point in time of associating the time stamp information and a point in time of recording the data stream by the body-external, portable processing device.
