WebMar 31, 2009 · Delta and theta are the homeostatic frequencies of human sleep. We recorded sleep EEG in 9- and 12-year-old cohorts twice yearly over a 5-year period. Delta power density (PD) was unchanged between age 9 and 11 years and then fell precipitously, decreasing by 66% between age 11 and 16.5 years ( P < .000001). WebApr 23, 2013 · HSPT defines a conspicuous, stereotypical, high-amplitude theta EEG burst, with a relatively ‘pure’ frequency of ∼7 Hz and a duration of ∼1.5–2 s. Spectral analysis shows a surging theta power at 7 Hz, and up to four harmonic peaks (14, 21, 28 and 35 Hz). We call these EEG events HSPT.
