These night terrors can occur each night if the individual does not eat a proper diet, get the appropriate amount or quality of sleep (e.g. sleep apnea), is enduring stressful events, or if they remain untreated. Adult night terrors are much less common, and often respond to treatments to rectify causes of poor quality or quantity of sleep.
Even if sleep-related violence may occur during an episode of confusional arousal, it remains extremely rare and there is no specific predisposition to aggression during these episodes. [ 8 ] Distinction between sleepwalking and night terrors

House suggests that the night terrors were a result in post-traumatic stress disorder from sexual abuse and his double vision was caused by a concussion and/or eye strain. Then he notices Dan's foot twitch with a myoclonic jerk which normally only occurs when falling asleep. He immediately admits Dan and starts diagnosis with his team.
The process of meiosis in females occurs during oogenesis, and differs from the typical meiosis in that it features a long period of meiotic arrest known as the dictyate stage and lacks the assistance of centrosomes. [53] [54] In males, meiosis occurs during spermatogenesis in the seminiferous tubules of the testicles.
Meiosis generates genetic variation in the diploid cell, in part by the exchange of genetic information between the pairs of chromosomes after they align (recombination). Thus, on this view, [28] an advantage of meiosis is that it facilitates the generation of genomic diversity among progeny, allowing adaptation to adverse changes in the ...
A pair of sister chromatids is called a dyad. A full set of sister chromatids is created during the synthesis phase of interphase, when all the chromosomes in a cell are replicated. The two sister chromatids are separated from each other into two different cells during mitosis or during the second division of meiosis.
In this stage there is a cytoplasmic division that occurs at the end of either mitosis or meiosis. At this stage there is a resulting irreversible separation leading to two daughter cells. Cell division plays an important role in determining the fate of the cell. This is due to there being the possibility of an asymmetric division.
