Patent number: 10716485Abstract: 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.Type: GrantFiled: November 9, 2015Date of Patent: July 21, 2020Assignees: The General Hospital Corporation, Massachusetts Institute of TechnologyInventors: Pavitra Krishnaswamy, Patrick Purdon, Gabriel Obregon-Henao, Matti Hamalainen, Behtash Babadi

The signals include first signals received from first pixel detectors corresponding to a first image area and second signals received from second pixel detectors corresponding to a second image area surrounding the first image area. Camera settings of a setting group are automatically controlled (340) based on the first signals. The settings group has at least one of focus control, exposure control and white balance control. Changes in the setting group are predicted based on the second signals.
