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.

Despite early success, the treatment was not developed until the 1930s by two independent groups of psychologists: Orval Mowrer and Willie Mae Mowrer (1938) and John Morgan and Frances Witmer (1939).

The court heard that two witnesses went into Smith's flat and saw the victim lying on the living room floor in a pool of blood. They left, and Mr Forbes jumped from the property.
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.
