Summary
Astrocytes, once thought passive, actively control synaptic transmission. New research using simultaneous electrophysiology and calcium imaging reveals complex astrocyte-neuron interactions crucial for brain function.
Area of Science:
- Neuroscience
- Cellular Biology
- Neurophysiology
Background:
- Historically, astroglial cells were viewed as passive support cells in the nervous system.
- Recent decades have revealed astrocytes actively participate in neural function.
- Their intimate contact with synapses suggests a role in synaptic transmission.
Purpose of the Study:
- To review the understanding of astrocyte-neuron interactions in synaptic efficacy control.
- To highlight the importance of simultaneous electrophysiological recordings and calcium imaging.
Main Methods:
- Simultaneous electrophysiological recordings of neuronal and astrocytic activity.
- Calcium imaging techniques to monitor astrocytic signaling.
- Analysis of ionic currents and neuro-glial dialogues.
Main Results:
- Astrocytes actively regulate synaptic transmission, challenging the simplistic view of their function.
- Calcium signaling is a key mechanism in astrocytic control of synaptic efficacy.
- Simultaneous recordings provide in-depth insights into neuro-glial communication.
Conclusions:
- Astrocytes are integral components in regulating synaptic efficacy.
- Understanding neuro-glial dialogues is essential for comprehending brain function.
- Advanced techniques are crucial for elucidating complex astrocyte-neuron interactions.

5.7K
Neurons communicate at synapses, or junctions, to excite or inhibit the activity of other neurons or target cells, such as muscles. Synapses may be chemical or electrical.
Most synapses are chemical, meaning an electrical impulse or action potential spurs the release of chemical messengers called neurotransmitters. The neuron sending the signal is called the presynaptic neuron, and the neuron receiving the signal is the postsynaptic neuron.

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.

Neurons are the main type of cell in the nervous system that generate and transmit electrochemical signals. They primarily communicate with each other using neurotransmitters at specific junctions called synapses. Neurons come in many shapes that often relate to their function, but most share three main structures: an axon and dendrites that extend out from a cell body.

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...
