Alexander A. Borbély (born 1939 in Budapest) is a Hungarian-Swiss pharmacologist known for his sleep research.. Borbély proposed the two-process model of sleep regulation in 1982 which postulates there are two complementary processes (S and C, which stands for Sleep and Circadian, respectively) which together account for one's sleep schedule. [1]
In 1993, a different model called the opponent process model [98] was proposed. This model explained that these two processes opposed each other to produce sleep, as against Borbely's model. According to this model, the SCN, which is involved in the circadian rhythm, enhances wakefulness and opposes the homeostatic rhythm.

A urine sensor is a necessary part of any bedwetting alarm. A basic urine sensor consists of two electricity conductors separated by moisture absorbing insulating material. A low DC electric voltage, provided by batteries, is applied across these conductors. This low voltage is usually about 3 volts, so as not to be dangerous to the user.
Chronic sleep problems are associated with an increased risk of obesity, type 2 diabetes, and heart disease. Inflammation. Chronic sleep deprivation can promote systemic inflammation, which is an ...
In the two process model of sleep, it has been proposed, that depression is characterized by a deficiency in the building up of process S. [27] Therefore, sleep deprivation might increase process S in the beginning, but a relapse occurs, when sleep deprivations isn't applied anymore and process S returns to a low level. [27]
Improvement to cognitive performance caused by exercise could last for 24 hours, a new study shows. Scientists also linked getting 6 or more hours of sleep to better memory test scores the next day.
This model proposes a homeostatic process (Process S) and a circadian process (Process C) that interact to define the time and intensity of sleep. [71] Process S represents the drive for sleep, increasing during wakefulness and decreasing during sleep until a defined threshold level, while Process C is the oscillator responsible for these levels.
