人脑活动中的时不变个人特定频率模板
Time-invariant person-specific frequency templates in human brain activity
摘要:
人类大脑的各种任务在不同的位置和时间尺度上执行。然而,我们发现存在时间不变(高于基本时间尺度)的大脑活动划分为个人状态特定的频带。为此,我们进行时间和合奏平均最好的小波包基从多电极EEG记录。这些个人频带为大脑功能的定量分析提供了新的模板,正常与癫痫活动。
英文摘要:
The various human brain tasks are performed at different locations and time scales. Yet, we discovered the existence of time-invariant (above an essential time scale) partitioning of the brain activity into personal state-specific frequency bands. For that, we perform temporal and ensemble averaging of best wavelet packet bases from multi-electrode EEG recordings. These personal frequency-bands provide new templates for quantitative analyses of brain function, e.g., normal vs. epileptic activity.
