Facilitated Transport01:19

Facilitated Transport

149.5K
The chemical and physical properties of plasma membranes cause them to be selectively permeable. Since plasma membranes have both hydrophobic and hydrophilic regions, substances need to be able to transverse both regions. The hydrophobic area of membranes repels substances such as charged ions. Therefore, such substances need special membrane proteins to cross a membrane successfully. In  facilitated transport, also known as facilitated diffusion, molecules and ions travel across a...

Social Facilitation

36.6K
Not all intergroup interactions lead to negative outcomes. Sometimes, being in a group situation can improve performance. Social facilitation occurs when an individual performs better when an audience is watching than when the individual performs the behavior alone. This typically occurs when people are performing a task for which they are skilled.

Facilitated Diffusion01:16

Facilitated Diffusion

1.3K
The plasma membrane, a critical structure in cellular biology, houses an array of transporters, or carrier proteins, interspersed within its lipid bilayer. These proteins play a crucial role in solute transport through facilitated diffusion, a form of passive diffusion that uses transporters to move the molecules across the membrane.
In this process, substrates such as organic compounds and ions interact with a transporter on one side, triggering conformational changes in proteins that enable...

Anatomical Movements00:51

Anatomical Movements

16.2K
Anatomical movements refer to the various actions or motions that can be performed by the body's joints and muscles. These movements are described using specific terms to provide a standardized way of discussing and understanding the range of motion at different joints.
Here are some common anatomical movements:
Flexion and extension motions are in the sagittal (anterior–posterior) plane of motion. These movements take place at the shoulder, hip, elbow, knee, wrist,...

The Movement of Organelles and Vesicles01:43

The Movement of Organelles and Vesicles

6.5K
In eukaryotic cells,  cytoskeletal filaments such as actin, microtubules, and intermediate filaments form a mesh-like cytoskeletal network. These filaments serve as tracks for transporting cellular cargo. Specialized motor proteins use the chemical energy stored in adenosine triphosphate (ATP) for this transport. During interphase, microtubules are polarized, with the plus-end towards the cell periphery and the minus-end towards the cell center. Two microtubule-associated motor proteins,...

Summary
This summary is machine-generated.

Movement repetition speeds up future similar movements by improving response preparation. This behavioral effect may mirror use-dependent plasticity observed in the brain's motor cortex.

Area of Science:

  • Neuroscience
  • Motor Control
  • Human Movement Science

Background:

  • The sensorimotor system is shaped by recent movement history.
  • Use-dependent plasticity describes how movement repetition affects involuntary cortical responses.
  • Behavioral evidence for repetition's effect on voluntary movement preparation has been limited.

Purpose of the Study:

  • To investigate how repeating movements influences future voluntary movement generation.
  • To determine if movement repetition enhances response preparation.
  • To explore the underlying mechanisms of this behavioral effect.

Main Methods:

  • Participants repeatedly performed movements in a specific direction.
  • Reaction times for selecting and preparing movements were measured.
  • Analysis focused on distinguishing rapid preparation from anticipatory preparation.

Main Results:

  • Movement repetition significantly reduced the time needed to select and prepare subsequent similar movements.
  • This reaction time advantage was linked to faster, flexible preparation, not anticipation.
  • The findings suggest a behavioral benefit of movement repetition on motor preparation.

Conclusions:

  • Movement repetition enhances future movement generation by improving response preparation.
  • This behavioral enhancement may be a counterpart to use-dependent plasticity in motor cortex.
  • Repetition offers a beneficial, rapid, yet flexible mechanism for motor control.
