Examples described herein may predict therapy efficacy and/or therapeutic parameters using a comparison of individual patient status data and brain network response maps for the therapy. For example, VNS parameters may be predicted using a comparison of patient EEG data and brain network response maps of VNS therapy at various parameters.

An information displaying system according to an embodiment of the present disclosure includes a first display section configured to display a time axis of detected signals along a first direction, a second display section configured to display a plurality of signal waveforms based on the detected signals in parallel so that the signal waveforms are arranged side by side in a second direction different from the first direction, and a controller configured to control the first display section and the second display section. When, in the second display section, a location on at least one of the plurality of the signal waveforms or near the at least one of the plurality of the signal waveforms is designated, the controller highlights the designated location, and displays a designated result on a time location in the first display section corresponding to the designated location.

An information display device includes a component extraction unit, a sorting unit, and a noise component selection unit. The component extraction unit is configured to perform a principal component analysis or an independent component analysis to extract desired components from a plurality of signal waveforms based on detected biological signals. The sorting unit is configured to sort a plurality of extracted results obtained by the component extraction unit in descending order of periodicity and display the sorted results. The noise component selection unit is configured to receive selection of one extracted result as a noise component from the extracted results obtained by the component extraction unit.

Embodiments disclosed herein directed to systems, apparatuses, and methods for the suppression of artifacts in non-invasive electromagnetic recordings. A data set, such as an electroencephalography (EEG) or magnetoencephalography (MEG) data set may be recorded by a number of sensors. The data set may include contributions from a signal of interest and from artifacts. The contribution of artifacts may be suppressed by splitting the data set into projected data and residual data based on a spatial model of the signal of interest. The projected data may contain contributions from the signal of interest and artifacts, while the residual data may primarily contain contributions from artifacts. The projected and residual data may be compared to remove or reduce the contribution of artifacts from the projected data.

A magnetoencephalography apparatus includes: a lead configured to be secured to a user's head; a first magnetic field sensor attached to the lead, the first magnetic field sensor including a substrate, and an electron spin defect layer on the substrate, the electron spin defect layer including at least one lattice defect, in which a first spin energy level of the at least one lattice defect splits upon exposure to a microwave; and cabling, in which the cabling includes a first microwave transmission line arranged to provide a first microwave field to the electron spin defect layer and in which the cabling includes an optical fiber arranged to provide, from a first end of the optical fiber, a first light signal to the electron spin defect layer and to receive, at the first end of the optical fiber, a second light signal emitted by the electron spin defect layer.
