... motor and premotor areas of the cerebral cortex. In this way, both the basal ganglia and the cerebellum have an essential and distinctive role in the organization (coordination, timing, and sequencing) of a normal motor output. Finally, the basal ganglia, as well as the cerebellum, play an important ...

Wide field-of-view, twin-region two-photon imaging across extended

By contrast, a expanded field-of-view (FOV) would cover more cortical area and enable investigations of activity in multiple cortical areas. (c) Raster scanning a larg ...

Where do mirror neurons come from?

... However, the associative hypothesis currently has three advantages. First, it provides a straightforward, empirically testable explanation for the differences between monkeys and humans that have led some researchers to question the existence of a ‘mirror neuron system’. Second, it is consistent wit ...

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.
