What are neurochemicals?
neurochemicals are chemicals involved in the functioning of the nervous system of the body. They have purposes such as regulating ideas and emotions, carrying signals from neurons and promoting the growth and repair of nervous system cells. Human neurochemistry can have deep effects on its health, abilities and behavior. Psychoactive drugs affect users by changing its neurochemistry and many health problems and disorders are the result of the inability to produce or absorb neurochemicals in the right quantity. The most common neurotransmitter in humans is glutamate, which is important for learning and memory. Excessive glutamate levels can annoy nerve cells and cause stroke, mental retardation and amyotrophic lateral sclerosis, also known as Lou Gehrig's disease. There are also indications that the excessive level of glutamuate can cause seizures. It is important for the brain reward system that causes pleasant feelings by releasing dopamine in response to stimuli such as food, sex and other sources of pleasure. InsufficientDopamine is involved in a disorder of hyperactivity with lack of attention and cause engine management problems such as tremor and slowed movements suffering from people with Parkinson's disease.
Serotonin is a neurotransmitter important for the digestive system and for perception of resources such as food, perception of the body. Some primitive animals release serotonin when food is detected, while serotonin relaxes after food consumption, which reduces appetite. Serotonin is also related to the perception of social power, dominance and submission. Serotonin is released when food is detected in the gastrointestinal tract, causing contractions that promote food through the tract. Serotonin levels when toxins are detected, either growing contractions that promote irritants through gastrointestinal tract and out of the body faster or in extreme cases, in extreme cases of chemoreceptor activation,that cause vomiting to eliminate the fastest substance.
endorphins are neurotransmitters produced in an intense feeling such as pain, sexual climax and physical exertion. It is an endogenous opioid that blocks feelings of pain and can cause feelings of well -being or euphoria. Some people involved in deliberate self -harm, such as cutting their own skin, because endorphins relaxed in response to injuries can cause temporary relief from stress or depression.
hormonal oxytocin is a neurotransmitter important in social connection, sexual excitement and maternal behavior. Increased oxytocin levels create feelings of peace, satisfaction and trust. It is assumed that the release of oxytocin and chemically similar hormonal vasopressin during sexual activity strengthens monogamous paired ties. Oxytocin is also released during breastfeeding and promotes maternal links.
Not all neurochemicals are neurotransmitters. Neurotrophins promote health and survival withThey stimulate neurons and stimulate neurogenesis, the creation of new neurons. Examples of neurotrophins include a neutrotrophic factor derived from the brain and a nervous growth factor that are important for the health of the nervous system. Animals unable to correctly produce neurotrophins have problems with neural development, resulting in neurological defects and premature death.
neurochemicals are essential for the effects of recreational drug use. Endogenic opoids such as morphine and heroin cause pain relief or feelings of euphoria through an endogenous opioid -like mechanism such as endorphins. Most recreational drugs produce at least part of their pleasant effect by stimulating dopamine release and this interaction with the brain rewarding system is an important factor depending on the drugs. The over -stimulated brain eventually begins to reduce the production of dopamine and dopamine receptors in response to excess, dulling the reaction dependent on pleasant stimuli in general and requires that the drug addictHe had higher his drug consumption to produce the same pleasant feelings as before.
neurochemical abnormalities are involved in a number of mental disorders. Scientists assumed that obsessive-compulsive disorder could be caused by a lack of serotonin reception, leading to increased anxiety. Some scientists also speculated that excessive production or sensitivity to dopamine causes psychosis and schizophrenia. Schizophrenics show increased activity in some of their dopaminergic pathways that transmit dopamine around the brain. Antipsychotic drugs usually operate by blocking dopamine intake and temporary psychosis can be induced drugs that cause extreme increase in dopamine levels such as cocaine and amphetamines.
