Protein Networks

Protein Networks

An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

Network Covalent Solids

Network Covalent Solids

Network covalent solids contain a three-dimensional network of covalently bonded atoms as found in the crystal structures of nonmetals like diamond, graphite, silicon, and some covalent compounds, such as silicon dioxide (sand) and silicon carbide (carborundum, the abrasive on sandpaper). Many minerals have networks of covalent bonds.
To break or to melt a covalent network solid, covalent bonds must be broken. Because covalent bonds are relatively strong, covalent network solids are typically...

Regulation of Stroke Volume

Regulation of Stroke Volume

The regulation of stroke volume, which is the amount of blood the heart pumps out during each heartbeat, is critical for maintaining a healthy circulatory system. Stroke volume is influenced by three main factors: preload, contractility, and afterload.
Preload refers to the degree of stretch on the heart before it contracts. It's analogous to the stretching of a rubber band; the more it's stretched, the more forcefully it snaps back. This concept is encapsulated in the Frank-Starling law of the...

Motor Units

Motor Units

The motor unit is a fundamental component of the neuromuscular system and plays a crucial role in coordinating muscle contractions. It consists of a somatic motor neuron, which connects and controls multiple skeletal muscle fibers, forming a single functional segment. The axon of the motor neuron branches out and establishes synaptic connections known as neuromuscular junctions with individual muscle fibers within the motor unit.
Motor units come in different sizes, with smaller units...

Motor Units

Motor Units

A motor unit consists of two main components: a single efferent motor neuron (i.e., a neuron that carries impulses away from the central nervous system) and all of the muscle fibers it innervates. The motor neuron may innervate multiple muscle fibers, which are single cells, but only one motor neuron innervates a single muscle fiber.

Summary

Stroke survivors show stronger parietofrontal connectivity during visually guided movements. This increased brain network coupling is linked to motor deficits, suggesting a role in post-stroke motor function and recovery.

Background:

Motor recovery after stroke varies greatly between individuals.
Visuomotor integration, crucial for daily activities, involves parietal brain regions.
The parietal motor system's adaptation post-stroke is less understood than the frontal system.

Purpose of the Study:

To investigate plastic changes in functional connectivity within parietal and frontal motor areas after stroke.
To assess the behavioral relevance of these changes for motor function recovery.

Main Methods:

High-density electroencephalography (EEG) was used in 30 chronic stroke patients and 19 healthy controls.
Task-related coherence in sensorimotor rhythms was measured during a visually guided grip task.
Changes in functional connectivity were correlated with residual motor deficits.

Main Results:

Parietofrontal functional connectivity was significantly stronger in stroke patients compared to controls.
Task-related coherence between parietal and primary motor cortex increased in the stroke-lesioned hemisphere across sensorimotor rhythms.
This increased parietofrontal coupling positively correlated with motor impairment (Nine-Hole Peg Test, grip force).

Conclusions:

Stroke-lesioned brains exhibit enhanced parietofrontal motor system integration during visually guided movements.
The heightened connectivity may serve as a marker of motor network damage or influence post-stroke motor function.
