Metastability in the brain

Metastability is a recently proposed description of neural dynamics of the brain. [1][2][3] A region of the brain may function autonomously for a moment, then become interdependent on other regions in the next moment, shifting between autonomous and interdependent (coordinated) activity. Metastability relates to the constant interplay between these autonomous and interdependent tendencies. [4] [5][6] With metastability, neural activity patterns can be coherent without becoming fixed. This is necessary for adaptive behavior while maintaining an overall robustness in response to changing environments.
