Inertia Tensor01:24

Inertia Tensor

1.1K
The concept of the inertia tensor is employed to depict the mass distribution and rotational inertia of a solid or rigid object. This tensor is expressed through a three-by-three matrix. Each component within this matrix corresponds to varying moments of inertia about specific axes.
The diagonal components of the inertia tensor matrix represent the moments of inertia concerning the principal axes of the object. These primary axes are defined as the axes where the object experiences the least...

Diffusion01:12

Diffusion

218.0K
Diffusion is the passive movement of substances down their concentration gradients—requiring no expenditure of cellular energy. Substances, such as molecules or ions, diffuse from an area of high concentration to an area of low concentration in the cytosol or across membranes. Eventually, the concentration will even out, with the substance moving randomly but causing no net change in concentration. Such a state is called dynamic equilibrium, which is essential for maintaining overall...

Diffusion

6.4K
Diffusion is a type of passive transport. In passive transport, a substance tends to move from an area of high concentration to an area of low concentration until the concentration is equal across the space. For example, take the diffusion of substances through the air. When someone opens a perfume bottle in a room filled with people, the perfume is at its highest concentration in the bottle and is at its lowest at the edges of the room. The perfume vapor will diffuse, or spread away, from the...

Higher Mental Functions of Brain: Learning and Memory01:26

Higher Mental Functions of Brain: Learning and Memory

2.1K
Memory is one of the most vital higher mental functions of the brain. Memory is closely related to learning because it enables us to retain information and experiences from our past to use them in our present life. It also helps us to remember facts, events, and skills, such as riding a bike or swimming. There are two types of memory — declarative memory, which involves memorizing facts or events, and procedural memory, which enables us to remember how to do something like writing or...

Protein Networks02:26

Protein Networks

4.5K
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,...

Plasticity00:58

Plasticity

3.1K
Plasticity is the property where an object loses its elasticity and undergoes irreversible deformation, even after the deformation forces are eliminated. If a material deforms irreversibly without increasing stress or load, then this is called ideal plasticity. For example, when a force is applied to an aluminum rod, it changes its shape, but it does not return to its original shape once the force is removed. Plastic deformation or ductility is thus a permanent deformation or change in the...

Area of Science:

  • Neuroscience
  • Cognitive Science
  • Sports Science

Background:

  • Motor skill acquisition and brain plasticity are key research areas.
  • Diffusion-tensor imaging (DTI) and graph theory enable study of brain network changes due to learning.
  • Limited research exists on the brain network topology of open-skill learning.

Purpose of the Study:

  • To investigate brain network topological features in high-level athletes with open-skill expertise.
  • To test the hypothesis that athletes have higher transmission efficiency and network interaction in specific brain regions.
  • To correlate training experience with brain network characteristics.

Main Methods:

  • Collected DTI data from 21 high-level basketball players and 25 controls.
  • Constructed brain networks and analyzed topological properties using graph theory.
  • Performed correlation analysis between training years and regional brain network parameters.

Main Results:

  • High-level athletes showed significantly higher global efficiency, shorter path length, and small-worldness in their brain networks.
  • Regional analysis revealed elevated nodal parameters in athletes, concentrated in visual, default mode, and attention networks.
  • Brain node parameter changes were significantly associated with the number of training years.

Conclusions:

  • High-level open-skill athletes possess distinct brain network topological features characterized by enhanced global efficiency and regional connectivity.
  • These findings suggest significant brain plasticity and adaptation in response to extensive motor skill training.
  • The study establishes a link between training duration and specific neural network alterations in athletes.
