The theory of synaptic tagging and capture (stc) establishes the relationship between the calcium concentration and the plasticity-related proteins.
The synaptic tagging and capture theory (stc) was postulated by frey and morris in 1997 and provided a strong framework to explain how to achieve synaptic.
The synaptic tagging and capture (stc) hypothesis of protein synthesis-dependent long-term potentiation (1, 2) may offer an explanation of this associative process, based on the idea that the neural mechanisms of initial long-term potentiation (ltp) expression (potentiation and tagging) can be dissociated from those regulating the availability of plasticity-related proteins (prps) that stabilize synaptic change.

Serves as a comprehensive introduction and overview of synaptic tagging and capture (stc) and covers the topic from molecular and cellular aspects to behavior. Circa 15 years ago the stc model was proposed to provide a conceptual basis for how short-term memories are transformed into long-term memories.
A related phenomenon called synaptic tagging and capture (stc) has been proposed as a mechanism for cellular memory consolidation and to account for temporal association of memories. Mounting evidences from behavioral settings suggest that stc could be a physiological phenomenon.

The mechanisms underlying initial memory consolidation are not well-understood, but the synaptic tagging and capture (stc) hypothesis provides a conceptual basis of synaptic plasticity events occurring during initial memory consolidation.
A a strong stimulus (ss) both tags a synapse and generates a genomic signaling cascade that leads to transcription and translation of proteins. 2 the function of the tag is to capture the protein 3 a weak stimulus (ws) will tag a synapse, but cannot generate a genomic signaling cascade.
The synaptic tagging and capture (stc) hypothesis of late-ltp (frey and morris, 1997) asserts that ltp involves the local “tagging” of synapses at the moment of induction, that tags capture diffusely transported “plasticity-related proteins” (prps) synthesized in the soma or local dendritic domains, and that tag–prp interactions are essential for stabilization of potentiation.
The model presented here incorporates biologically constrained dendritic compartments, depolarization-dependent plasticity mechanisms, synaptic tagging and capture, and changes in neuronal excitability in neurons embedded in a cortical microcircuit to study memory engram formation.
The synaptic tagging and capture theory provided a strong framework to explain synaptic specificity and persistence of electrophysiological induced plastic changes.
The synaptic tagging and capture (stc) hypothesis explains this by dissociating synapse-specific tagging from diffusible plasticity-related products (prps) — that is, proteins and mrnas.

In isolated hippocampal slices, decaying long-term potentiation (ltp) can be stabilized, and converted to late-ltp lasting many hours, by prior or subsequent.
Support for this interpretation comes from experiments that show an increase in mrna for erk2 and raf-1 24 h after ltp induction22.
Both stc and cross-tagging involve two serial processes: (1) setting of the synaptic tag as triggered by a specific pattern of stimulation, and (2) synaptic capture, whereby the synaptic tag interacts with newly synthesized plasticity-related proteins (prps).
4 synaptic capture of newly synthesized protein another feature of the synapse tag and capture hypothesis is the selective capture of newly synthesized proteins at potentiated synapses. There can be several ways to deliver proteins to the tagged synapses.
About this book serves as a comprehensive introduction and overview of synaptic tagging and capture (stc) and covers the topic from molecular and cellular aspects to behavior. Circa 15 years ago the stc model was proposed to provide a conceptual basis for how short-term memories are transformed into long-term memories.
The synaptic tagging and capture hypothesis of protein synthesis-dependent long-term potentiation asserts that the induction of synaptic potentiation creates.
The synaptic tagging and capture (stc) process, characterized by the tag-plasticity related protein (prp) interactions, forms the basis of associative memories. The stc hypothesis provides a conceptual basis of how short-term forms of plasticity are transformed into long-term forms of plasticity in an associative and time-dependent manner.
Since synaptic tagging and capture results from ltp and/or ltd in hippocampus, and the making of memories relies crucially on both hippocampal ltp and ltd, it is likely that synaptic tagging-and-capture plays a key role in memory consolidation and organization.

An important concept in synaptic plasticity is the synaptic tag and capture (stc) hypothesis (frey and morris,1997), which was developed to explain how the protein synthesis-dependent component of ltp retained input-specificity given the need for proteins to be delivered to synapses from the soma.

The synaptic tagging and capture theory provided a strong framework to explain synaptic specificity and persistence of electrophysiological induced plastic changes. Ten years later, the behavioral tagging hypothesis (bt) made use of the same argument, applying it to learning and memory models.
The synaptic tag and capture (stc) hypothesis provides an important theoretical basis for understanding the synaptic basis of associative learning. We recently provided pharmacological evidence that calcium-permeable ampa receptors (cp-ampars) are a crucial component of this form of heterosynaptic metaplasticity.
