Summary
This review details the molecular machinery governing neuronal synapse function, including neurotransmitter release, plasticity, and circuit refinement. Understanding these synaptic mechanisms is crucial for addressing neurological disorders.
Area of Science:
- Neuroscience
- Molecular Biology
- Cell Biology
Background:
- Neuronal synapses are critical for central nervous system communication.
- Synaptic function involves complex molecular interactions at pre- and postsynaptic sites.
Purpose of the Study:
- To review the molecular mechanisms regulating synaptic transmission, plasticity, and circuit refinement.
- To highlight the molecular players involved in synapse formation, function, and elimination.
Main Methods:
- Literature review of molecular mechanisms in synaptic biology.
- Analysis of protein interactions and signaling pathways at synapses.
Main Results:
- Detailed description of presynaptic machinery (scaffolding proteins, SNARE complex, calcium channels) and vesicle dynamics.
- Overview of postsynaptic density organization, receptor anchoring, and synaptic plasticity mechanisms (LTP/LTD).
- Explanation of synapse development, elimination (microglial pruning), and molecular diversity.
Conclusions:
- Synaptic homeostasis is essential for normal brain function.
- A unified model of synaptic regulation is needed to understand neuropsychiatric and neurological disorders.

Neurons communicate with one another by passing on their electrical signals to other neurons. A synapse is the location where two neurons meet to exchange signals. At the synapse, the neuron that sends the signal is called the presynaptic cell, while the neuron that receives the message is called the postsynaptic cell. Note that most neurons can be both presynaptic and postsynaptic, as they both transmit and receive information.

Electrical synapses found in all nervous systems play important and unique roles. In these synapses, the presynaptic and postsynaptic membranes are very close together (3.5 nm) and are actually physically connected by channel proteins forming gap junctions.
Gap junctions allow the current to pass directly from one cell to the next. In contrast, in the chemical synapse, the neurotransmitters carry the information through the synaptic cleft from one neuron to the next. They consist of two...

Chemical synapses are specialized sites between two neurons or between a neuron and a non-neuronal cell like a muscle, glandular or sensory cell.
Because chemical synapses depend on the release of neurotransmitter molecules from synaptic vesicles to pass on their signal, there is an approximately one millisecond delay between when the axon potential reaches the presynaptic terminal and when the neurotransmitter leads to opening of postsynaptic ion channels. Additionally, this signaling is...

01:25Overview of Synapses
5.2K
A synapse is a specialized structure where two neurons connect, allowing them to pass an electrical or chemical signal to another neuron. It is the point of communication between neurons. The term "synapse" is derived from the Greek word "synapsis," which means "conjunction." The entire process of neural communication revolves around the synapse. When activated, a neuron releases chemicals known as neurotransmitters into the synapse. These neurotransmitters cross the synapse and bind to...
