M a rc h 3, 2 0 1 6. Non-human research: neonatal castration increases preference for male sexual partners in adulthood, neonatal testosterone to females increases preference for sexual partners in adulthood. No reliable diference between the brains of homosexuals and heterosexuals has been discovered. We sleep about 175 000 hours in our lifetime. It is a critical function to stay alive and like functioning. Electroencephalography electroencephalograms (eeg), electrical activity, in the skin and the brain. Frequency decreases over time alert wakefulness has more peaks and valleys = more activity, decreasing frequency to stage 4. Amplitude increases larger and longer peaks of activity to stage 4. Transition to stage 1 is sudden from awake to asleep is very fast: all other transitions are more gradual. Stage 2 more gradual stage changes: sleep spindle brief burst of activity, k complex higher amplitude and up/down lexion. Stage 3 gradual appearance of delta waves. Stage 4 deepest stage of sleep.
