Abstract: In some examples, a processor determines a patient state based on activity of a bioelectrical brain signal of a patient in one or more frequency sub-bands of a frequency band of interest. For example, a processor may determine a patient state based on the power level of a bioelectrical brain signal of the patient in one or more frequency sub-bands of a frequency band, or based on a spectral pattern of a bioelectrical brain signal in a frequency band, such as a shift in a power distribution between sub-bands, a change in the peak frequency within one or more sub-bands, a pattern of the power distribution over one or more frequency sub-bands, or a width or a variability of one or more sub-bands exhibiting a relatively high or low level of activity.

Abstract translation: 在一些示例中，处理器基于感兴趣的频带的一个或多个频率子带中的患者的生物电脑信号的活动来确定患者状态。 例如，处理器可以基于频带的一个或多个频率子带中的患者的生物电脑信号的功率水平，或者基于频率的生物电脑信号的频谱图来确定患者状态 频带，例如子频带之间的功率分配的偏移，一个或多个子带内的峰值频率的变化，一个或多个频率子带上的功率分布的模式，或宽度或变化性 的一个或多个子带表现出相对较高或低水平的活性
