What are Neuromodulating Compounds?
The definition of neuromodulating compounds (also known as neuromodulators) is flexible but has evolved to describe neurotransmission that is not directly excitatory or inhibitory. Neuromodulating compounds are chemical messengers released from neurons in the central nervous system (CNS) or periphery nervous system (PNS) that affects groups of neurons or effector cells with the appropriate receptors.
There are many types of neuromodulating compounds, such as opioid peptides like enkephalins, endorphins, dynorphins. Examples of neuromodulating compounds are also neurotransmitters, including acetylcholine, dopamine, histamine, norepinephrine, serotonin, and octopamine. They are not released at synaptic sites; however, they act through second messengers and produce long-lasting effects. The release of them is local so that only nearby neurons or effectors are influenced or more widespread, meaning that the distinction with a neurohormone becomes very blurred.
Roles of Neuromodulating Compounds in CNS
Neuromodulation underlies the flexibility of neural circuit operation and behavior. Neuromodulation is demonstrated as a change in the state of a neuron or group of neurons that alters its response to subsequent stimulation and the strength of signal transmissions between neurons. Neuromodulating compounds can alter neuronal signal transmission by controlling the number of neurotransmitters synthesized and released by the neurons.
For Neuronal Activity
Neuromodulating compounds play critical roles in regulating every aspect of neuronal activity. Their functional roles are typically identified using various pharmacological and genetic approaches to activate or block specific neuromodulating compounds and characterize the resulting functional consequences.
For Synaptic Communication
Neuromodulating compounds modify synaptic communication through several mechanisms, which can be broadly divided into effects that target synapses directly and those that indirectly modify synaptic interactions by changing the excitability of neurons.

For Regulating Plasticity
Neuromodulating compounds play a ubiquitous role across the brain in regulating plasticity. Neuromodulating compounds are thought to impact plasticity predominantly through two mechanisms: the gating of plasticity and the upregulation of neuronal activity. They are often thought to convey global control of brain states that underlie different behaviors, such as sleep, arousal, and anesthetized states.
