Systems, devices, and techniques for adjusting electrical stimulation based on a posture state of a patient are described. For example, processing circuitry is configured to receive an input from a user adjusting an informed stimulation parameter that at least partially defines a plurality of informed pulses, determine a ratio of a first value of an informed stimulation parameter to a first value of a control stimulation parameter that at least partially defines a plurality of control pulses, change, according to the input, the first value of the informed stimulation parameter to a second value of the informed stimulation parameter, and change, based on the input and the ratio, the first value of the control stimulation parameter to a second value of the control stimulation parameter. The processing circuitry' can then control delivery of the adjusted control pulses and informed pulses.

Methods and systems for recording evoked potentials evoked during electrical stimulation of a patient's neural tissue are disclosed. The methods and systems are useful with treatment modalities, such as spinal cord stimulation (SCS). The disclosed methods and system allow for stimulation artifacts to be reduced in, or removed from, the recorded signals. A residual portion of the stimulation artifact can be modeled and subtracted from a recorded signal that includes both artifact and neural response contributions.

Systems and methods are described herein for determining whether cardiac conduction system pacing therapy may be beneficial and/or determining how proximal or distal a cardiac conduction system block may be using external cardiac signals. To do so, one or more left-sided metrics of electrical heterogeneity information may be generated based on left-sided surrogate cardiac electrical measured using a plurality of left external electrodes.

Disclosed herein is a system and method implementing an automated, generalizable model for tracking cortical spreading depressions using EEG. The model comprises convolutional neural networks and graph neural networks to leverage both the spatial and the temporal properties of CSDs in the detection. The trained model is generalizable to different head models such that it can be applied to new patients without re-training. Further, the model is scalable to different densities of EEG electrodes, even when trained on a specific electride density.

The present invention relates to systems and methods for improvement of physiological function in an individual with a spinal cord injury via electrical stimulation of the spinal cord. A 3D model of the spinal cord is used to determine an initial position for an electrode array to deliver stimulation. Spinal cord electrical stimulation is configurable to target different physiological functions with surgical implantation of the neurostimulator at a singular location. Such systems and methods include (i) anatomical specificity to target the appropriate region of the spinal cord for stimulation, (ii) electrical specificity to provide the appropriate stimulation by delivery method, frequency, pulse duration, and other factors, and (iii) physiological specificity to evoke, suppress, increase, or decrease a specific physiological result.

Systems, devices, methods, and techniques are described for using evoked compound action potential (ECAP) signals to determine an implant location for a lead. An example method includes receiving first information representative of a first evoked compound action potential (ECAP) signal sensed in response to a first control stimulus delivered to a first location adjacent to a spinal cord of a patient. The method also includes receiving, second information representative of a second ECAP signal in response to a second control stimulus delivered to a second location adjacent to the spinal cord of the patient. Additionally, the method includes outputting a first indication of the first information representative of the first ECAP signal and a second indication of the second information representative of the second ECAP signal.

Disclosed and contemplated herein is a bispectral EEG (BSEEG) method which can detect patients with delirium and can detect delirium with systemic inflammation. In various implementations, a mouse model is used to detect delirium with systemic inflammation induced by lipopolysaccharide (LPS) injection.
