Cross-Frequency Coupling in Descending Motor Pathways: Theory and Simulation

Descending pathways in motor control.

Each of the descending pathways involved in motor control has a number of anatomical, molecular, pharmacological, and neuroinformatic characteristics. They are differentially involved in motor control, a process that results from operations involving the entire motor network rather than from the brain commanding the spinal cord. A given pathway can have many functional roles. This review explor...

Developmental plasticity of descending motor pathways.

Juvenile animal brains are highly plastic and thus often achieve better functional recovery after injury compared with adult brains. Recently, Umeda et al. (Umeda T, Takahashi M, Isa K, Isa T. J Neurophysiol 104: 1707-1716, 2010) have shown that the remodeling of both corticospinal and extra-pyramidal pathways can contribute to the recovery of grasping and reaching ability in hemidecorticated j...

Neural Cross-Frequency Coupling Functions

Although neural interactions are usually characterized only by their coupling strength and directionality, there is often a need to go beyond this by establishing the functional mechanisms of the interaction. We introduce the use of dynamical Bayesian inference for estimation of the coupling functions of neural oscillations in the presence of noise. By grouping the partial functional contributi...
