BRAIN AND NERVOUS SYSTEM
WHAT ARE NEUROTRANSMITTERS, AND HOW DO THEY AFFECT PEOPLE?
ОглавлениеAccording to the effect that neurotransmitters have on the "receiving" nerve terminal, they are divided into excitatory: they increase the action potential and generate a new impulse, and inhibitory: block the action potential achievement in the postsynaptic nerve ending. Some neurotransmitters, such as dopamine and acetylcholine, can have both stimulatory and suppressive effects, depending on the type of receptors on the postsynaptic membrane.
Next, we will talk about several neurotransmitters that have a powerful effect on various aspects of human life, both physiological and psychological.
DOPAMIN is called the neurotransmitter of winners, and scientists describe it as one of the key factors of internal reinforcement. Its formation helps to remember positive experiences: for example, when a person tastes good food, receives praise, has sex, and achieves a goal. The dopamine release is followed by euphoria: the brain remembers it and motivates the person to have the positive experience again. Dopamine plays an important role in learning processes, and it is also involved in the regulation of muscle function. When dopamine production is impaired, so-called dopamine diseases, like Parkinson's disease and schizophrenia, develop.
