And I've been meaning to incorporate the content of Talk : Metastability in molecules into the article once I get around to creating some proper images.

A version of this situation appears as metastability in digital electronics, when a circuit must decide between two states when there is an input that is changing value.
33.
In the past 25 years, interest in metastability and the underlying framework of nonlinear dynamics has been fueled by advancements in the methods by which computers model brain activity.
34.
This protection can often take the form of a series of delay flip-flops which delay the data stream long enough for metastability failures to occur at a negligible rate.
35.
Metastability of free flow means that for small disturbances free flow remains stable ( free flow persists ), but with larger disturbances the flow becomes unstable and a F ?
36.
Chemical substances or states can persist indefinitely even though they are not in their lowest energy state if they experience metastability-a state which is stable only if not disturbed too much.
37.
A changing circuit is supposed to settle into one of a small number of desired states, but if the circuit is vulnerable to metastability, it can get stuck in an undesirable state.
38.
The metastability problem is a significant issue in digital circuit design, and metastable states are a possibility wherever asynchronous inputs ( digital signals which are not synchronized to a clock signal ) occur.
39.
The dynamical system model, which represents networks composed of integrated neural systems communicating with one another between unstable and stable phases, has become an increasingly popular theory underpinning the understanding of metastability.

This work is aimed at understanding how human social interaction is mediated by metastability of neural networks . fMRI and EEG are particularly useful in mapping thalamocortical response to social cues in experimental studies.
