Summary
Electrical synapses, or gap junctions, are dynamic and modifiable, not passive channels. Research shows these crucial neural connections exhibit plasticity, similar to chemical synapses.
Area of Science:
- Neuroscience
- Cell Biology
- Biophysics
Background:
- Synapses facilitate neural information processing via chemical or electrical transmission.
- Chemical synapses are well-studied, but electrical synapse plasticity remains less understood.
- Electrical synapses, mediated by gap junctions, were historically viewed as passive.
Purpose of the Study:
- To explore the dynamic and modifiable properties of electrical synapses.
- To discuss factors influencing electrical transmission strength.
- To review evidence of electrical synapse plasticity.
Main Methods:
- Literature review of existing research on electrical synapses.
- Analysis of data demonstrating the modifiability of gap junctions.
- Comparison of electrical and chemical synapse properties.
Main Results:
- Electrical synapses are more dynamic and modifiable than previously thought.
- Factors influencing the strength of electrical transmission have been identified.
- Evidence supports the plasticity of electrical synapses, akin to chemical synapses.
Conclusions:
- Electrical synapses are active and adaptable components of neural circuits.
- Understanding electrical synapse plasticity is crucial for comprehending neural function.
- This research contributes to the understanding of communicating junctions and their dysfunctions.

01:37Gap Junctions
Multicellular organisms employ a variety of ways for cells to communicate with each other. Gap junctions are specialized proteins that form pores between neighboring cells in animals, connecting the cytoplasm between the two, and allowing for the exchange of molecules and ions. They are found in a wide range of invertebrate and vertebrate species, mediate numerous functions including cell differentiation and development, and are associated with numerous human diseases, including cardiac and...
01:27Gap Junctions
The cytoplasm of adjacent animal cells can exchange small molecules, ions, and secondary messengers via the communication channels which form the gap junctions. These junctions comprise a few hundred to thousands of molecular channels, each made of two halves, called the connexon hemichannel. A connexon is a hexamer of six transmembrane connexin proteins, which assemble radially, thus forming a pore or channel in the center. One connexon hemichannel docks with a corresponding connexon on the...
01:28Electrical Synapses
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...

01:12Mechanically-gated Ion Channels
Mechanically-gated ion channels are proteins found in eukaryotic and prokaryotic cell membranes that open in response to mechanical stress. Tension, compression, swelling, and shear stress can alter the conformation of the protein, opening a transmembrane channel that allows the passage of ions for signal transmission. In eukaryotes, mechanically-gated channels are distributed in several regions like the neurons, lungs, skin, bladder, and heart, where they play critical roles in numerous...

01:19Contact-dependent Signaling
Contact-dependent signaling, as the name suggests, requires that communicating cells be in direct contact with each other. This is achieved either through receptor-ligand interactions or by specialized cytoplasmic channels that allow the flow of small molecules between cells. In animal cells, channels called gap junctions facilitate contact-dependent signaling in certain tissues, whereas, plasmodesmata perform a similar function in plants.
