A device is provide for stimulating neurons. The device includes a stimulation unit that is implantable into a patient's body and that includes multiple stimulation elements for stimulating neurons in a target area of the brain and/or spinal cord of the patient with stimuli. Moreover, the device includes a control unit that actuates the stimulation unit such that multiple groups of stimulation elements generate respective stimuli. In this aspect, each group includes multiple stimulation elements of the stimulation unit with two or more of the groups generating sequences of stimuli in a repetitive manner in a respective time pattern which includes successive cycles. Furthermore, the sequences of stimuli generated by the two or more groups differ in terms of the number of cycles in which the sequence in which the stimulation elements generate the stimuli within one sequence is constant and/or in terms of the duration of respective cycles.
