nerve signaling chemicals.

Chemical "messages" that are passed between neurons.

Chemicals liberated at the terminals of an axon that cross the synaptic gap and have excitatory or inhibitory effects on the postsynaptic neuron (e.g., norepinephrine, serotonin, GABA).

the substance that is released when the axon terminal of a presynaptic neuron is excited. The substance then travels across the synapse to act on the target cell to either inhibit or excite it. Disorders in the brain physiology of neurotransmitters have been implicated in the pathogenesis of a variety of psychiatric illnesses.

Chemicals in the brain that help communicate messages from cell to cell, and are crucial in thinking, memory, and emotion.

chemicals that carry electrical signals between neurons

chemicals, released by neurons at their terminals, that act on other neurons.

Endogenous signaling molecules that alter the behaviour of neurons or effector cells. Neurotransmitter is used here in its most general sense, including not only messengers that act directly to regulate ion channels, but also those that act through second messenger systems, and those that act at a distance from their site of release. Included are neuromodulators, neuroregulators, neuromediators, and neurohumors, whether or not acting at synapses.

the information in the form of a chemical messenger that passes through the synapses.

chemicals that send nerve impulses from neuron to neuron.

Chemicals used to carry messages throughout the brain's network of cells.

Chemical agents released by a neuron (nerve cell) to send a signal to the neighboring neuron; successive releases by each neighboring neuron allow for communication throughout the nervous system.

Brain chemicals that travel from one neuron or nerve cell (the presynaptic cell) across a small gap (the synaptic cleft) to attach to receptor molecules on the surface of the second neuron (the postsynaptic cell), thereby carrying a signal between cells. Neurotransmitters include norepinephrine, serotonin, dopamine and acetylcholine. The most is known about serotonin and norepinephrine.

These are chemical substances used for communication between one nerve cell and the next. There are many neurotransmitters, although there are only a few that are very common and account for a lot of the communication functions in the brain. Some of the most commonly studied neurotransmitters are dopamine, acetylcholine, serotonin, glutamate and norepinephrine, GABA (gamma-amino-butyric acid), glycine. close window

Molecules exchanged between neural cells as a form of communication and simulation. This includes ions (e.g. calcium, sodium), monoamines (e.g. serotonin, dopamine) and even basic nutrients such as glucose.

Chemical substance that enables communication between nerve cells; can stimulate or inhibit neurons by binding to them.

A human body chemical structure that is secreted upon certain nerve stimuli, and acts as a catalyst to biochemical or nerve action.

Naturally occurring chemicals in the brain which transmit messages from one nerve cell to another.

Brain chemicals that communicate between nerve cells, and are thought to be largely responsible for a person's feelings, emotions, actions and behavior.

Body chemicals that cause nerve impulses between nerve fibers

chemicals in the brain that are believed to regulate mood or emotion.

endogenous chemicals that relay signals between cells.

Chemicals in the brain that carry messages between nerve cells.

Substances that transmit signals from one nerve to another.

Chemicals in the brain that help carry messages between brain cells.

chemicals that help to send messages through the nerves in your body.

Substances produced in neurons that promote or inhibit the conduction of nerve impulses, such as epinephrine, norepinephrine, dopamine, serotonin, and gamma-aminobutyrate.

chemical substances that carry impulses from one nerve cell to another; found in the space (synapse) that separates the transmitting neuron's terminal (axon) from the receiving neuron's terminal (dendrite).

Naturally occurring chemicals that carry messages along the nervous system; examples include epinephrine, norepinephrine, and acetylcholine.

Chemicals that transfer messages from one nerve cell to another or from a nerve cell to a muscle cell. In the brain, neurotransmitters are believed to play a role in depression and anxiety disorders.

Chemicals in the brain that aid in the transmission of nerve impulses. Various Neurotransmitters are responsible for different functions including controlling mood and muscle movement and inhibiting or causing the sensation of pain.

Chemicals produced in neurons to send messages.

The chemical messengers of the nervous system. They are released at the synapse (connection between nerve cells) and influence cell behavior. Common neurotransmitters include glutamate, serotonin, acetylcholine and norepinephrine.

Chemicals released from the tip of an axon into the synaptic cleft when a nerve impulse arrives; may stimulate or inhibit the next neuron. The chemical that crosses the synaptic cleft and causes the transmission of the nerve message in an adjacent neuron or the stimulation of an effector cell (muscle or gland). PICTURE

A specialized biochemical substance (such as norepinephrine, serotonin, dopamine, endorphin or acetylcholine) that transfers nerve impulses across spaces between nerve cells (synapses). Neurotransmitters are naturally produced chemicals by which nerve cells communicate.

substances that transmit nerve impulses to the brain.

A substance, such as serotonin, norepinephrine or dopamine, that is released when a nerve cell connection is excited. These substances can bind to another cell and cause some sort of effect.

Chemicals that transmit nerve impulses across a space (or synapse) from one nerve to another

Chemical substances produced by axons that transmit messages across the synapses.

Chemical substance released by one neuron that acts upon a second neuron or upon a muscle or gland cell that alters its electrical state or activity.

Chemical substances that transmit signals between neurons and that modulate neuronal activity.

substances transmitting the signals among brain cells.

chemicals secreted by neurons that provide the means of synaptic transmission. (72)

Chemicals in the brain, such as acetylcholine, serotonin and norepinephrine, that facilitate communication between nerve cells (neurons).

chemicals that transmit nerve signals from one neuron to another.

NAAR glossary Chemicals released by neurons into the synapse to communicate with each other. Some neurotransmitters are "excitatory" and cause the next cell to fire, some are "inhibitory" and prevent the next cell from firing.

Chemical substances that transmit information from one cell to another, via the space (synapsis) between nerve cells.

Chemical messengers released from neurons.

A chemical that is used to transmit a message between nerve cells in the brain. Two neurotransmitters that are very important in the treatment of schizophrenia are dopamine and serotonin.

A compound made by the nerve cells that allows for communication between it and other cells.

chemical messengers that carry messages or signals between the various nerves in the brain; the neurotransmitters serotonin, dopamine, and norepinephrine are believed to be the chemical messengers responsible for moods and emotions.

a chemical mediator released by a presynaptic nerve ending that interacts with receptor molecules in the post synaptic membrane

Chemicals that transmit information across the synapse to communicate from one neuron to another.

Biochemical substances that stimulate or inhibit nerve impulses in the brain that relay information about external stimuli and sensations, such as pain.

the chemicals around nerve cells through which messages travel in the brain and central nervous system

Chemicals in the brain that help messages pass from one area of the brain to another.

Signaling molecules that are used by nerve cells to communicate with one another.

are the chemical language of the brain. . . the chemical messengers that facilitate communication between nerve cells. Neurotransmitters come from amino acids and are produced by neurons in the cells of the brain.

chemicals that stimulate adjacent neurons.

Chemicals such as serotonin or norepinephrine that convey messages across the gap (synapse) between adjoining neurons (see Anxiety, Depression, Hypertension).

Neurotransmitters are the messengers that travel between one brain cell and another. They are chemical signals that neurons use to talk to each other, which is what makes your brain work. They help determine how you feel, think, and act.

chemicals in the brain that regulate other chemicals in the brain.

chemicals that transmit nerve impulses between neurons. Some neurotransmitters include acetylcholine, dopamine, endorphin, epinephrine, serotonin, and histamine.

Endogenous chemical components that are released from axon terminals of one neuron and transmit the signal to the next neuron by combining with its receptor molecules. Examples of neurotransmitters that appear to be important in the control of sleep and wakefulness include: norepinephrine, serotonin, acetylcholine, dopamine, adrenaline and histamine. The process of neurotransmission may be inhibited, modulated, or enhanced by other chemical mediators within the brain, or by exogenous pharmaceuticals.
