Device and method for examining a phase distribution used to determine a pathological interaction between different areas of the brain

A device for examining a pathological interaction between different brain areas, including a stimulation unit, which administers identical stimuli to a patient in a sequential manner, wherein the stimuli stimulate neurons of the patient in the brain areas to be examined, a measuring unit for recording measurement signals that represent a neural activity of the stimulated neurons, and a control and analysis unit for controlling the stimulation unit and for analyzing the measurement signals.

20170333711 · 2017-11-23 ·

A device that suppresses a pathological synchronous and oscillatory neuron activity, and includes a non-invasive stimulation for stimulation, using stimuli, of neurons in the patient's brain and/or spinal cord, where those neurons are showing pathologically synchronous and oscillatory neuron activity, and the stimuli are designed to suppress are this activity when administered to the patient. Moreover, a measuring unit records measurement signals reflecting the neuron activity of the stimulated neurons and a control and analysis unit controls the stimulation unit to administer stimuli, check the success of stimulation based on the measurement, and, if the stimulation success is not sufficient, insert one or more stimulation breaks in the application of the stimuli or extend one or more stimulation breaks, where no stimuli that could suppress the pathological synchronous and oscillatory neuron activity are applied during the stimulation breaks.

DEEP BRAIN SOURCE IMAGING WITH M/EEG AND ANATOMICAL MRI

A method for non-invasively resolving electrophysiological activity in sub-cortical structures located deep in the brain by comparing amplitude-insensitive M/EEG field patterns arising from activity in subcortical and cortical sources under physiologically relevant sparse constraints is disclosed. The method includes a sparse inverse solution for M/EEG subcortical source modeling. Specifically, the method employs a subspace-pursuit algorithm rooted in compressive sampling theory, performs a hierarchical search for sparse subcortical and cortical sources underlying the measurement, and estimates millisecond-scale currents in these sources to explain the data. The method can be used to recover thalamic and brainstem contributions to non-invasive M/EEG data, and to enable non-invasive study of fast timescale dynamical and network phenomena involving widespread regions across the human brain.
