You tell me what love is.

Love is a strong attachment, closeness and yearning between individuals (mostly people), and it is also a selfless and all-out emotion. Usually it is the contrast between love and desire. Love consists of two parts: love and sex. Love is the soul of love, and sex is an additional attribute of love, so it is not necessary to exist. Love is the root and core of love.

In China culture, love is to seize each other's heart. Love has the attributes of intimacy, lust and commitment, attachment and emotion, and has confidence in the durability of this relationship, and can also share private life with each other. On the emotional basis of love, in addition to the cross-cultural differences of love, the concept of love has also changed greatly with the passage of time (different national cultures have also developed different characteristics).

Love is an inseparable part of human nature. In a narrow sense, it refers to the feelings between lovers. In a broad sense, it also includes love between friends and love between relatives (love feelings).

In 2000, a study led by Samadzeki and Andreas bartels of University College London concluded that at least two areas of the brain become more active during love. These are focal media islands, which connect the brain with its instinct and a part of the anterior cingulate cortex, and are related to excited emotions.

There is a "love ring" in the brain that can control love. This "love circle" consists of four small areas. These areas are called "ventral tegmental area" (VTA for short), nucleus accumbens, ventral globus pallidus and nucleus raphe.

Studies have found that the chemical activity of love in the brain is the same as that of drug addiction. Brain scans of people who broke up quickly showed extra activity in the nucleus accumbens. Lucy Brown, a neuroscientist at Einstein College of Medicine, said that this phenomenon represents craving, "similar to the craving for drugs".

Scientists conducted this experiment among people who have been in love for 20 years, and found that in addition to the ventral tegmental area, the ventral pallidum and raphe nucleus area also became brighter. Fischer said that the ventral globus pallidus is responsible for love emotions and stress-relieving hormones, and the raphe nucleus is responsible for releasing serotonin, which has a "calming" effect.
