There are many different types of neurotransmitters. Some of the main types of neurotransmitters are Acetylcholine, which is responsible for stimulation of muscles; Norepinephrine, which is responsible for bringing our nervous system to high alert; Dopamine, which is associated with reward mechanisms; Serotonin which affects your mood and emotion, and Endorphin which is like your natural pain killer.
The people responsible for discovering these chemicals are Otto Loewi, who discovered Acetylcholine in 1921. Acetylcholine was also the first to be discovered. Loewi also won the nobel prize for his discovery. Then in 1946 Ulf Von Euler discovered Norepinephrine. And in the 1950’s Dopamine was discovered by Arvid Carlsson also in 1950 Eugene Roberts and J. Awapara discovered GABA or gamma aminobutyric acid. in the 1930’s Vittorio Erspamer discovered Serotonin.The people responsible for discovering Endorphin are Solomon Snyder and Candace pert in 1973.
There are two types of neurotransmitters, inhibitory and excitatory. Inhibitory neurotransmitters balance mood and are easily depleted. Excitatory neurotransmitters stimulate the brain. Too much or too little of any of these chemicals can cause disorders such as A.D.H.D and A.D.D. Neurotransmitters are chemicals that transmit signals across a synapse. A synapse is what permits a nerve cell to pass an electrical or chemical signal to another cell. After which, the signal is then transmitted to another nerve cell. The neurotransmitters in your brain are stored in small sacks by the synapse at the end of the neurons axon terminal. Axon terminals are projections of neuron cells that conducts electrical impulses.

Neurotransmitters are not the same as neurons. And thats because, first of all There are 100 billion neurons and only 100 known neurotransmitters. Neurons are cells while neurotransmitters are chemicals. Also once you lose neurons you cannot regain them.

Briefly explain the process of neurotransmission. Neurotransmission starts with the neuron, the most important part of the central nervous system. A neuron contains a cell body, axon, and dendrites. When a neuron receives an electrical impulse, the impulse travels away from the cell body down the axon. The axon breaks off into axon terminals. At the axon terminals, the electrical impulse creates a neurotransmitter. The neurotransmitter is released into the synapse, a space between two neurons. If the neurotransmitter tries to stimulate a response of another neuron, it is an excitatory neurotransmitter. If the neurotransmitter does not stimulate a response of another neuron it is an inhibitory neurotransmitter. If a response is generated, the second neuron or postsynaptic neuron will receive an action potential at the site of the dendrite and the communication process will continue on. If a response is not generated, neurotransmitters left in the synapse will be absorbed by the first neuron or presynaptic neuron, a process known as reuptake. Neurotransmitters control our body functions, emotions, and

Endorphins are produced by the pituitary gland and hypothalamus in response to stress, pain, love, sexual activity, excitement, and fear. They are chemicals that occur naturally in the brain which interact with opiate receptors to block sensations of pain and over all lead to feelings of euphoria. Hormones and neurotransmitters, such as endorphins, play a crucial role in the functioning of our bodies. Levels of endorphins in the brain can be altered by taking a number of drugs including heroin and methadone and lasting effects can ensue.
The central nervous system is a collection of cells within the brain specialized to send specific signals throughout the body in order to relay the messages necessary for proper functioning. The way these cells, also called neurons, communicate with one another is through the process of releasing neurotransmitters. A balanced proportion of neurotransmitters are crucial for a healthy functioning mind. In situations where the neurotransmitters get out of sync by becoming too prevalent or sparse within the synaptic clefts, a wide spectrum of mental illness can be the result.
Neurotransmitters are chemicals made by neurons and used by them to transmit signals to the other neurons or non-neuronal cells (e.g., skeletal muscle; myocardium, pineal glandular cells) that they innervate. The neurotransmitters produce their effects by being released into synapses when their neuron of origin fires (i.e., becomes depolarized) and then attaching to receptors in the membrane of the post-synaptic cells. This causes changes in the fluxes of particular ions across that membrane, making cells more likely to become depolarized, if the neurotransmitter happens to be excitatory, or less likely if it is inhibitory.
Neuropeptides are small molecules that help neurons communicate with one another. They represent the lar...

Chemical messengers transmit information from nerve cells to nerve cells in the body and the brain. Your nerve cells are called neurons, and their chemical messengers are called neurotransmitters. Chemicals like hallucinogens can disrupt this communication system, and the results are changes in the way you sense the world around you. There's still a lot that scientists don't know about the effects of hallucinogens on the brain, though. Some hallucinogens occur naturally in trees, vines, seeds, fungi and leaves.
