Summary
Human coordination dynamics reveal self-organized patterns in brain and behavior. Non-equilibrium phase transitions, like synchronization shifts, offer insights into neural and movement stability.
Area of Science:
- Human movement science
- Neuroscience
- Coordination dynamics
Context:
- Coordination dynamics studies human movement for over 20 years.
- Research spans bimanual, postural, interpersonal, and limb-environment coordination.
- Self-organized nature of human coordination is consistently observed.
Purpose:
- Review literature on brain and behavior coordination dynamics.
- Investigate synchronization and syncopation rhythmic patterns.
- Explore non-equilibrium phase transitions in human coordination.
Summary:
- Synchronization (on-beat) and syncopation (in-between beat) are key rhythmic patterns.
- Syncopation destabilizes near 2 Hz, leading to spontaneous synchronization (phase transition).
- Phase transitions reveal pattern formation/dissolution and system instability.
Impact:
- Brain imaging (MEG, EEG, fMRI) identifies neural signatures of stability.
- Highlights self-organization and metastability principles in brain function.
- Unifies empirical and theoretical frameworks for behavioral and brain dynamics.

02:17Microtubule Instability
Microtubules are hollow cylindrical filaments having a diameter of approximately 25 nm and a length that varies from 200 nm to 25 μm. GTP-bound tubulin subunits form αβ-heterodimers for microtubule assembly. These core building blocks interact longitudinally, polymerizing into protofilaments. The protofilaments then interact with one another through lateral bonding forces to form stable cylindrical microtubules. These cylindrical filaments are dynamic as they undergo repeated assembly and...
01:23Stability of Equilibrium Configuration
Understanding the stability of equilibrium configurations is a fundamental part of mechanical engineering. In any system, there are three distinct types of equilibrium: stable, neutral, and unstable.
A stable equilibrium occurs when a system tends to return to its original position when given a small displacement, and the potential energy is at its minimum. An example of a stable equilibrium is when a cantilever beam is fixed at one end and a weight is attached to the other end. If the weight...

01:13Functional Brain Systems: Reticular Formation
The reticular formation is a complex network of gray and white matter located within the brainstem extending from the medulla to the midbrain.
Within the reticular formation, there are several distinct nuclei that can be classified into three broad categories. The Raphe nuclei are located along the midline of the brainstem. They are primarily known for their role in synthesizing and releasing serotonin, a neurotransmitter involved in regulating mood, appetite, sleep, and circadian rhythms. The...

01:13Stability of Equilibrium Configuration: Problem Solving
The stability of equilibrium configurations is an important concept in physics, engineering, and other related fields. In simple terms, it refers to the tendency of an object or system to return to its equilibrium position after being disturbed. The stability of an equilibrium configuration can be analyzed by considering the potential energy function of the system and examining its behavior near the equilibrium point.

01:32Cytoskeletal Coordination in Cell Migration
A migrating cell changes its shape during the cyclic events of attachment and detachment from the substratum and repositions the cell organelles correspondingly. These complex events are orchestrated by the dynamic cytoskeletal network comprising actin filaments, intermediate filaments, and microtubules. Cytoskeletal crosstalk — the direct and indirect communication between the different components — is crucial for this coordination. Direct communication involves various linker proteins that...
01:28Stability
The time response of a linear time-invariant (LTI) system can be divided into transient and steady-state responses. The transient response represents the system's initial reaction to a change in input and diminishes to zero over time. In contrast, the steady-state response is the behavior that persists after the transient effects have faded.
The stability of an LTI system is determined by the roots of its characteristic equation, known as poles. A system is stable if it produces a bounded...
