It's a petroleum product, though, and as far as your driveway or garage floor is concerned, it produces the same kinds of stains. Power steering fluid stains, like oil stains, are easier to remove when they're fresh, but if your car has a leak, you probably won't get to the stain right away.
Serotonin (/ËsÉrÉËtoÊnáµ»n, ËsÉªÉrÉ-/) or 5-hydroxytryptamine (5-HT) is a monoamine neurotransmitter. Biochemically derived from tryptophan, serotonin is primarily found in the gastrointestinal tract (GI tract), blood platelets, and the central nervous system (CNS) of animals, including humans. It is popularly thought to be a contributor to feelings of well-being and happiness.
The function of serotonin depends on the region of the brain into which it is released (it also depends on the type of serotonin receptor present in that region). For example, the serotonin neurons in the neocortex in the front of the brain (frontal cortex) regulate cognition, memory, and perceptions.
