On mathematical foundation of the Brownian motor theory
Brownian motors diffusion effective drift effective diffusivity Bloch decomposition
2015/9/25
The paper contains mathematical justification of basic facts concerning the Brownian motor theory. The homogenization theorems are proved for the Brownian motion in periodic tubes with a constant drif...

Motor Learning Mechanism on the Neuron Scale
Motor learning neural mechanism cerebellum sensory-motor integration
2015/6/10
Based on existing data, we wish to put forward a biological model of motor system on the neuron scale. Then we indicate its implications in statistics and learning. Specifically, neuron’s firing frequ...

Stability of the frog motor nerve terminal: roles of perisynaptic Schwann cells and muscle fibers.
Organization and maintenance of the motor nerve terminal: Roles for presynaptic actin and perisynaptic Schwann cells
Frog neuromuscular actin nerve terminals protein cell skeleton
2014/12/11
At the adult frog neuromuscular junctions (Rana pipien and Rana catesbiana), F-actin microfilaments are enriched in the nonrelease domains of nerve terminals, outside the vesicle-rich release sites. T...
Dopamine Controls Locomotion by Modulating the Activity of the Cholinergic Motor Neurons in C. elegans
dopamine receptor elegans acetylcholine GAP neurotransmission
2014/12/9
Dopamine is an important neurotransmitter in the brain, where it plays a regulatory role in the coordination of movement and cognition by acting through two classes of G protein-coupled receptors to m...
NEW YORK, NY (January 22, 2014) — Columbia University Medical Center (CUMC) researchers have identified a gene, called matrix metalloproteinase-9 (MMP-9), that appears to play a major role in motor ne...
The University of Queensland’s Queensland Brain Institute (QBI) has welcomed the support of the MND and Me Foundation in its quest to improve the understanding of Motor Neuron Disease (MND).
Tensegrity and Motor-Driven Effective Interactions in a Model Cytoskeleton
Tensegrity Motor-Driven Effective Interactions Model Cytoskeleton Biological Physics
2012/4/24
Actomyosin networks are major structural components of the cell. They provide mechanical integrity and allow dynamic remodeling of eukaryotic cells, self-organizing into the diverse patterns essential...
Iterative Solution of Maxwell's Equations for an Induction Motor
Iterative Solution of Maxwell's Equations Induction Motor General Physics
2012/4/19
In this work we use classical electromagnetism to analyse a three-phase induction motor. We first cast the motor as a boundary value problem involving two phenomenological time-constants. These are de...
Spindles and active vortices in a model of confined filament-motor mixtures
Spindles active vortices confined filament-motor mixtures
2011/8/18
Abstract: Robust self-organization of subcellular structures is a key principle governing the dynamics and evolution of cellular life. In fission yeast cells undergoing division, the mitotic spindle s...
Coupling between switching regulation and torque generation in bacterial flagellar motor
Supramolecular assembly switching regulation and torque generation bacterial flagellar motor
2011/8/26
The bacterial flagellar motor plays a crucial role in both bacterial locomotion and chemotaxis. Recent experiments reveal that the switching dynamics of the motor depends on the motor rotation speed, ...
Chunking Patterns Reflect Effector-dependent Representation of Motor Sequence
Motor Sequence Chunking Patterns
2015/8/12
Sequential organization is central to much of human intelligent behavior ranging from everyday skills such as lacing shoes to using a computer. It is well known that such sequential skills involve cha...
Influence of direct motor-motor interaction in models for cargo transport by a single team of motors
motor-motor interaction models cargo transport
2011/1/6
We analyze theoretically the effects of excluded-volume interactions between motors on the dynamics of a cargo driven by multiple motors. The model considered shares many commons with other recently p...
