Relationships Between Neuronal Oscillatory Amplitude and Dynamic Functional Connectivity

Oscillatory Neurocomputers with Dynamic Connectivity

Our study of thalamo-cortical systems suggests a new architecture for a neurocomputer that consists of oscillators having different frequencies and that are connected weakly via a common medium forced by an external input. Even though such oscillators are all interconnected homogeneously, the external input imposes a dynamic connectivity. We use Kuramoto’s model to illustrate the idea and to pr...

Dynamic functional connectivity.

Recent studies show that anatomical and functional brain networks exhibit similar small-world properties. However, the networks that are compared often differ in what the nodes represent (e.g. sensors or brain areas), what kind of connectivity is measured, and what temporal and spatial scales are probed. Here, I review studies of large-scale connectivity and recent results from a variety of rea...

The Relationship Between Dynamic Stability and Functional Movement Screening Test

Purpose: Recently, the Functional Movement Screen (FMS) and Y Balance Tests are used to assess the key movement patterns, dynamic stability and to identify individuals at high risk of injury. But, there are few studies to assess the relationship between the FMS test and Y Balance Test. This study aimed to assess the relationship between dynamic stability and the FMS test. Methods: The subjects...

Childhood Trauma and Functional Connectivity between Amygdala and Medial Prefrontal Cortex: A Dynamic Functional Connectivity and Large-Scale Network Perspective

Altered functional connectivity (FC) between the medial prefrontal cortex (mPFC) and amygdala is widely implicated as a neural mechanism explaining risk for psychopathology among those exposed to early life trauma. Nonetheless, contemporary neuroimaging research has shifted toward large-scale network models of brain function, and it is not clear how this common bi-nodal finding fits into larger...
