Summary
Endocannabinoids (ECBs) regulate neural plasticity in the brain. Their modifiability, termed metaplasticity, influences how synaptic plasticity occurs, highlighting their crucial role in brain function.
Area of Science:
- Neuroscience
- Molecular Biology
- Neurophysiology
Background:
- Endocannabinoids (ECBs) are widespread in the brain, modulating synaptic transmission.
- Neural plasticity encompasses physiological changes of varying durations.
- Understanding ECBs' role in plasticity is crucial for comprehending brain function.
Purpose of the Study:
- To review recent developments in the role of endocannabinoids in mammalian neural plasticity.
- To explore how ECBs regulate synaptic plasticity.
- To examine how neuronal activity modulates ECBs' actions.
Main Methods:
- Literature review focusing on research published since 2006.
- Analysis of studies investigating endocannabinoid signaling pathways.
- Synthesis of findings on endocannabinoid-mediated metaplasticity.
Main Results:
- Endocannabinoids (ECBs) significantly regulate synaptic plasticity.
- The modifiability of ECB mobilization acts as metaplasticity, influencing subsequent synaptic changes.
- Neuronal activity dynamically regulates ECBs' function and availability.
Conclusions:
- Endocannabinoids are key regulators of neural plasticity and metaplasticity.
- Further research is ongoing to fully elucidate the complex functions of ECBs.
- This chapter provides an updated perspective on ECBs' role in synaptic plasticity.

01:01Neuroplasticity
Neuroplasticity reflects the brain's remarkable capacity to adapt and evolve, responding dynamically to learning, experiences, or injury by reorganizing its neural circuitry. This reorganization involves creating new neural connections and refining old ones through a series of biological processes that contribute to the brain's lifelong development and adaptability.
01:35Long-term Potentiation
Long-term potentiation, or LTP, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTP is the process of synaptic strengthening that occurs over time between pre- and postsynaptic neuronal connections. The synaptic strengthening of LTP works in opposition to the synaptic weakening of long-term depression (LTD) and together are the main mechanisms that underlie learning and memory.

00:58Plasticity
Plasticity is the property where an object loses its elasticity and undergoes irreversible deformation, even after the deformation forces are eliminated. If a material deforms irreversibly without increasing stress or load, then this is called ideal plasticity. For example, when a force is applied to an aluminum rod, it changes its shape, but it does not return to its original shape once the force is removed. Plastic deformation or ductility is thus a permanent deformation or change in the...
01:24Intracellular Signaling Cascades
Once a ligand binds to a receptor, the signal is transmitted through the membrane and into the cytoplasm. The continuation of a signal in this manner is called signal transduction. Signal transduction only occurs with cell-surface receptors, which cannot interact with most components of the cell, such as DNA. Only internal receptors can interact directly with DNA in the nucleus to initiate protein synthesis. When a ligand binds to its receptor, conformational changes occur that affect the...
01:12Synaptic Signaling
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.
