Synapsiviekojia

Synapsiviekojia is a theoretical concept in neuroscience that denotes a proposed state of neural communication where synaptic signaling and non-synaptic cues, particularly glial activity and extracellular signals, are coordinated across a microcircuit to regulate plasticity. Proponents describe it as a distributed form of synaptic modification in which vesicle release dynamics, receptor trafficking, and gliotransmitter signaling are synchronized beyond single synapses, producing network-wide changes that persist longer than typical synaptic events.

Origins and scope: The term is a neologism introduced in recent speculative discussions and a small subset of theoretical models. It has not been established in experimental literature, and there is no consensus on its existence or exact definition. Its use is primarily in thought experiments, computer simulations, and educational contexts to illustrate how local learning rules might scale to networks under glial influence.

Mechanisms and implications: In proposed models, synapsiviekojia would involve coordinated modulation of presynaptic release, postsynaptic receptor availability, and gliotransmission, leading to metaplastic changes that alter the learning rate of connected neurons. If applicable in vivo, it could help explain rapid, distributed plasticity and certain patterns of network dysregulation observed in some neurological conditions.

Relation to established concepts: It is related to, but distinct from, synaptic plasticity, metaplasticity, and gliotransmission. It is not a defined pathology or widely accepted mechanism at present.
