How dopamine works Dopamine action in the central nervous system In the brain, dopamine is used for communication between nerve cells, i.e. it is a nerve messenger (neurotransmitter). In certain “circuits” it mediates positive emotional experiences (“reward effect”), which is why it – like serotonin – is considered a happiness hormone. Compared to serotonin, however, … Dopamine: Effects, uses, side effects
What is dopamine? A particularly large amount of dopamine is produced in the midbrain. Here it plays an important role in the control and regulation of movements. If the dopaminergic neurons die, the dopamine effect is extinguished and characteristic symptoms such as tremor and muscle stiffness (rigor) appear. This clinical picture is also called Parkinson’s … Dopamine: What the Laboratory Value Means
The branch-like and multiply branched cytoplasmic processes of a nerve cell (neuron), through which information is received and impulses are transmitted to the body, is referred to in technical language as the dendrite. This serves to receive electrical stimuli and transmits them to the cell body (soma) of the nerve cell. What is a dendrite? … Dendrite: Structure, Function & Diseases
Ondansetron is a major antiemetic that belongs to the setrone class of drugs. Ondansetron achieves its effects by causing inhibition of 5HT3 receptors. Because of this mode of action, ondansetron is also considered a serotonin receptor antagonist. The drug is marketed under the trade name Zofran and is used to treat nausea, vomiting, and emesis. … Ondansetron: Effects, Uses & Risks
Lithium has been known as a very effective psychotropic drug since the mid-20th century. It is used primarily as a so-called phase prophylactic for bipolar and schizoaffective disorders and unipolar depression. Because the therapeutic window is very small, close monitoring of blood counts is required during lithium therapy to avoid intoxication. What is lithium? Lithium … Lithium: Effects, Uses & Risks
The receptor potential is the response of sensory cells to a stimulus and generally corresponds to depolarization. It is also called generator potential and is a direct consequence of the transduction processes by which the receptor converts a stimulus into excitation. In receptor-associated diseases, this process is impaired. What is the receptor potential? The receptor … Receptor Potential: Function, Role & Diseases
Introduction Serotonin is a very important hormone for the human body – if its concentration is too low, it can have many different consequences. As a so-called neurotransmitter, serotonin serves to transmit information in the human brain. It is known to play a role in the processing of emotions, but is also important for the … Serotonin deficiency – symptoms and therapy
Therapy options The assumption that a lack of serotonin can be increased by the administration of this hormone is not correct. However, there are drugs that influence serotonin levels through various mechanisms. Various antidepressants are used in the treatment of depression. It is important to know that serotonin, as a messenger substance between nerve cells … Therapy options | Serotonin deficiency – symptoms and therapy
Causes of serotonin deficiency A serotonin deficiency can be caused at different levels: For example, if the building blocks for the production of the hormone are missing, the concentration drops. The main component of serotonin is L-tryptophan, a so-called essential amino acid. This means that L-tryptophane cannot be produced by the body itself and must … Causes of serotonin deficiency | Serotonin deficiency – symptoms and therapy
Serotonin deficiency in children Since the diagnosis “serotonin deficiency” as such is difficult to make, it should be handled with great care, especially in children. If a child shows himself more listless than usual, separates himself from his friends and becomes more inattentive at school, a psychotherapist specially trained for children and adolescents should first … Serotonin deficiency in children | Serotonin deficiency – symptoms and therapy
The synaptic cleft represents the gap between two nerve cells within a chemical synapse. The electrical nerve signal from the first cell transforms into a biochemical signal at the terminal node and transforms back into an electrical action potential in the second nerve cell. Agents such as drugs, medications, and toxins can interfere with the … Synaptic Cleft: Structure, Function & Diseases
Almost everyone who has reached the age of puberty knows the famous “butterflies in the stomach“. They refer to a feeling that puts the body in a complete state of emergency and, for the most part, suspends rational thought – infatuation. What is infatuation? Infatuation is a strong feeling of affection, which differs from the … Infatuation: Function, Tasks, Role & Diseases
