Neurons in visuomotor areas such as FEF or the lateral intraparietal area often exhibit sustained activation in the absence of visual stimulation, such as in memory-guided saccade tasks (e.g., Chafee and Goldman-Rakic 2000; Lawrence et al. 2005; Thompson et al. 2005). Conversely, neurons in V4 and o ...

Metastability in the brain

In the field of computational neuroscience, the theory of metastability refers to the human brain’s ability to integrate several functional parts and to produce neural oscillations in a cooperative and coordinated manner, providing the basis for conscious activity.Metastability, a state in which signals (such as oscillatory waves) fall outside their natural equilibrium state but persist for an extended period of time, is a principle that describes the brain’s ability to make sense out of seemingly random environmental cues. 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.
