is a substance that is produced by a neuron that is other than a neurotransmitter and is used to transmit information to other neurons to regulate their activities. examples are dopamine, s.erotonin or histamine
These are typically known as neuromodulators; they can either change the rate at which a neurotransmitter is released, or alter the response to a certain neurotransmitters.
Neuropeptides that affect a neuron's response to other neurotransmitters are called neuromodulators. They can enhance or inhibit the effects of neurotransmitters, thereby influencing neuronal excitability and synaptic transmission. By modulating the activity of neurotransmitters, neuromodulators play a crucial role in regulating various physiological processes, including pain perception, mood, and stress responses.
Enkephalins and endorphins are neuromodulators because they can influence the activity of neurotransmitters in the brain by interacting with specific receptors, altering the cell's response to those neurotransmitters. This modulation can result in changes in pain perception, mood, and overall brain function.
A neuromodulator modifies or makes more or less efficient the synaptic action of a neurotransmitter. Whereas a neurotransmitters work as chemicals released from terminal vesicles into synaptic clefts to receptors depolarizing the next neuron and initiates an electrical charge.
Neuromodulators are chemicals that can change the activity of neurons in the brain. They can affect how neurons communicate with each other, which can influence brain function and behavior. Neuromodulators can either enhance or inhibit the activity of neurons, helping to regulate processes like learning, memory, mood, and motivation.
Neurotransmitters are chemical messengers that transmit signals between nerve cells, while hormones are chemical messengers that regulate various bodily functions. Neurotransmitters act locally at synapses, while hormones travel through the bloodstream to target cells.
Neurotransmitters released from one neuron can either excite or inhibit the next neuron. Excitatory neurotransmitters make the receiving neuron more likely to fire an action potential, while inhibitory neurotransmitters make it less likely. This process allows for communication and coordination between neurons in the nervous system.
Neurotransmitters act on synapses.
Not all molecules that act as neurotransmitters in the brain are considered "true" neurotransmitters. Some molecules, like gases (e.g., nitric oxide), lipids (e.g., endocannabinoids), and peptides (e.g., endorphins), can also act as neurotransmitters but are not classified as traditional neurotransmitters like dopamine or serotonin due to their unique chemical properties and modes of action. These non-traditional neurotransmitters play important roles in modulating neural signaling and can have significant effects on behavior and physiology.

Neurons release neurotransmitters.
Neurotransmitters to the synapse and the neurotransmitters bind with the receptors releasing the second messengers.
