Target type: biologicalprocess
Any process that increases the frequency, rate or extent of mini excitatory postsynaptic potential. Mini excitatory postsynaptic potential is a process that leads to a temporary increase in postsynaptic potential due to the flow of positively charged ions into the postsynaptic cell, induced by the spontaneous release of a single vesicle of an excitatory neurotransmitter into the synapse. [GOC:aruk, GOC:bc, PMID:20395454]
Positive regulation of mini excitatory postsynaptic potential (mEPSP) is a complex process that involves the modulation of neurotransmitter release at presynaptic terminals, leading to an increase in the amplitude or frequency of miniature excitatory postsynaptic potentials (mEPSPs). These miniature events represent spontaneous release of neurotransmitter from a single vesicle, providing a baseline measure of synaptic strength.
**Mechanisms of Positive Regulation:**
1. **Presynaptic Calcium Signaling:** Increased calcium influx into the presynaptic terminal is a primary mechanism for enhancing mEPSPs. This can occur through:
* **Increased presynaptic action potential firing:** Higher frequency of action potentials leads to greater calcium entry through voltage-gated calcium channels.
* **Enhanced calcium channel activity:** Modulation of calcium channel properties, such as increased opening probability or prolonged open time, can boost calcium influx.
* **Calcium buffering:** Changes in the concentration of calcium buffers within the presynaptic terminal can alter the availability of calcium for neurotransmitter release.
2. **Synaptic Vesicle Pool Modulation:** The number and availability of synaptic vesicles primed for release can be regulated, influencing mEPSP frequency.
* **Increased vesicle docking and priming:** Factors that promote the docking and priming of synaptic vesicles at the active zone increase the likelihood of spontaneous release.
* **Increased vesicle recycling:** Efficient recycling of released vesicles back to the readily releasable pool contributes to sustained neurotransmitter release.
3. **Neurotransmitter Release Machinery:** Proteins involved in the fusion of synaptic vesicles with the presynaptic membrane can be modulated.
* **Synaptotagmin:** This calcium sensor protein plays a critical role in triggering vesicle fusion. Increased synaptotagmin activity can enhance the efficiency of neurotransmitter release.
* **SNARE proteins:** These proteins mediate vesicle docking and fusion. Alterations in the activity or expression of SNARE proteins can affect the rate of vesicle release.
4. **Synaptic Plasticity:** Changes in synaptic strength, including an increase in mEPSPs, are often associated with learning and memory processes.
* **Long-term potentiation (LTP):** This form of synaptic plasticity involves persistent enhancement of synaptic transmission, often through increased presynaptic release probability.
* **Synaptic scaling:** This mechanism adjusts synaptic strength across the entire neuron in response to changes in overall activity.
**Consequences of Positive Regulation:**
* Increased synaptic strength: Higher mEPSPs indicate a stronger connection between neurons, potentially enhancing signal transmission.
* Enhanced neuronal excitability: Elevated mEPSP frequency can increase the likelihood of postsynaptic neurons firing action potentials.
* Modulatory role in neuronal circuits: Positive regulation of mEPSPs can contribute to the fine-tuning and plasticity of neural circuits.
**Note:** The specific mechanisms involved in positive regulation of mEPSPs can vary depending on the neuronal subtype, neurotransmitter involved, and the physiological context.
