Summary
Neurons can release multiple neurotransmitters from the same cell, impacting brain information processing and motor control. This review explores the mechanisms and functional significance of this complex neuronal communication.
Area of Science:
- Neuroscience
- Molecular Biology
- Neurophysiology
Background:
- Some neurons co-release multiple neurotransmitters.
- These neurotransmitters can be stored in the same or different vesicles.
- Co-transmission plays a role in brain function and motor control.
Purpose of the Study:
- To review molecular mechanisms of multi-neurotransmitter storage in neurons.
- To discuss functional implications of co-transmission for brain information processing.
- To examine the role of co-transmission in motor control circuits.
Main Methods:
- Literature review of molecular mechanisms.
- Analysis of functional implications for neural circuits.
- Synthesis of current knowledge on co-transmission.
Main Results:
- Multiple neurotransmitters can be stored within the same neuronal population.
- Storage mechanisms involve vesicular packaging and release dynamics.
- Co-transmission significantly influences neural signaling and information processing.
Conclusions:
- Neuronal co-transmission is a key mechanism for complex brain function.
- Understanding co-transmission is crucial for deciphering information processing and motor control.
- Further research into molecular mechanisms can reveal therapeutic targets.

01:29Excitatory and Inhibitory Effects of Neurotransmitters
12.4K
When an action potential reaches the presynaptic axon terminal, it releases neurotransmitters from the neuron into the synaptic cleft at a chemical synapse. The released neurotransmitter can be excitatory or inhibitory. The critical criteria commonly used to determine whether a molecule is a neurotransmitter at a chemical synapse are the molecule's presence in the presynaptic neuron. Second, its release is in response to strong presynaptic depolarization. And lastly, the presence of...

01:30Classification of Neurotransmitters
4.9K
Neurotransmitters play a crucial role in the communication between neurons in the autonomic nervous system. Neurons in the autonomic nervous system can be cholinergic or adrenergic depending on the neurotransmitters synthesized. Cholinergic neurons use acetylcholine as their primary neurotransmitter. This includes all the preganglionic fibers of the sympathetic and pre- and postganglionic fibers of the parasympathetic nervous systems. In addition, neurons of the somatic nervous system also use...

01:26Neurochemical Transmission: Sites of Drug Action
3.4K
Neurochemical transmission, the conduction of electrical impulses between neurons mediated by neurotransmitters, plays a vital role in various physiological processes. Autonomic drugs exert their effects by modulating neurotransmission within the autonomic nervous system. For instance, drugs such as hemicholinium block the precursor uptake necessary for synthesizing acetylcholine, an essential autonomic neurotransmitter. Following synthesis, neurotransmitters are stored in vesicles. Metyrosine...

01:27Adrenergic Neurons: Neurotransmission
5.1K
Postganglionic sympathetic fibers (except those supplying the sweat glands) releasing noradrenaline or norepinephrine are called noradrenergic or adrenergic neurons. Noradrenaline, dopamine, adrenaline, or epinephrine are collectively called "catecholamines" as they contain a catechol moiety and an amine side chain. The five stages of neurotransmitter release involve their synthesis, storage, release, reuptake and metabolism.

01:21Drugs Affecting Neurotransmitter Release or Uptake
1.5K
Certain drugs can affect how neurotransmitters called catecholamines, are released or taken back up in the adrenergic neuron. They can have different effects on the body's sympathetic transmission. Reserpine, a natural compound found in the Rauwolfia shrub, blocks a transporter called vesicular monoamine transporter (VMAT), which leads to a buildup of catecholamines in the cell and reduces sympathetic transmission. Another drug called guanethidine works in multiple ways, including blocking...

01:30Ligand-Gated Ion Channel Receptor: Gating Mechanism
3.7K
Ligand-gated ion channels are transmembrane proteins that play a vital role in intercellular communication and functions of the nervous system. They allow the influx of ions across the membrane once the neurotransmitter binds, allowing the subsequent transmission of electrical excitation across the neurons. Other ligand-gated ion channels, like the γ-aminobutyric acid (GABA) receptor, permit anions like chloride into the cells on the binding of the GABA molecule. Their entry into the cell...
