What is the role of neurotransmitters in the brain?

Electrical pulses move between nerve cells in an effort to perform basic sensory and motor information by synapses, space between nerve cells. Most synapses are chemical and, given the depolarization, at any time when the action potential comes to the end of the neuron axon, it cannot move through the gap until the electrical signals are transformed into chemical. Neurotransmitters are chemical messengers who work on nerve signals across synaptic cleft between neurons to affect the functioning of other nerve cells or glands. Some neurotransmitters in the brain regulate the action of other neurotransmitters, which further increases or reduces their effects postsynaptic. Acetylcholine affects vegetative functioning, including heart rate, breathing and muscle cell activity, depending on this. When it acts to the central nervous system, the brain, its action is excited; If it is in the peripheral nervous system, it is inhibitory. Biogenic amines affect nAlalad, because their changes are associated with certain disorders, including schizophrenia of mental illness, and Parkinson's disease that occurs due to destruction of neurons producing dopamines. Psychotropic drugs such as antidepressants are used primarily for their effects on brain biogenic amines.

amino acid acid gamma-aminobuytrric acid (GABA) and glycine are neurotransmitters in the brain that prevent nervous fire in the brain and spinal cord. Gaba increase drugs such as barbiturates and benzodiazepines. The most available of all inhibitory neurotransmitters of the brain, GABA, is important for the eyesight and control of the effect of skeletal muscle.

opiates such as codeine and morphine are strong analgesics, a group of drugs prescribed for pain relief that do not cause complete loss of consciousness. Natural endorphins are produced by the body in the form of endogenous opioids such as beta-endorphin and eobefalin, which affects opioid receptors in the brain and inhibits pain impulses. Opioids also act as neuromodulators by regulating the effects of other types of neurotransmitters in the brain.

Some drugs have an effect on neurotransmitters in the brain that can cause or lead to addiction, also referred to as drug abuse. Agonists are substances that are able to work in the same way or can increase the effects of some neurotransmitters. This is achieved either by increasing the effects on the receptors or by disabling the restore. Antagonists are medicines sitting on receptors without provoking an effect, preventing neurotransmitters in relation to receptors.
