Protein-protein Interfaces02:04

Protein-protein Interfaces

14.7K
Many proteins form complexes to carry out their functions, making protein-protein interactions (PPIs) essential for an organism's survival. Most PPIs are stabilized by numerous weak noncovalent chemical forces. The physical shape of the interfaces determines the way two proteins interact. Many globular proteins have closely-matching shapes on their surfaces, which form a large number of weak bonds. Additionally, many PPIs occur between two helices or between a surface cleft and a...

Cognitive Dissonance

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

Pulse rhythm01:30

Pulse rhythm

1.4K
Pulse rhythm refers to the pattern of pulsations within specific intervals, offering valuable insights into the regularity or irregularity of the heart's beats as observed through the pattern of pulsation within specific intervals. A regular pulse exhibits a consistent heart rate with uniform waveforms and pulsation force, variations of which can be classified as normal, weak, or bounding.
Conversely, an irregular pulse pattern is termed dysrhythmia, stemming from disruptions in cardiac...

Disturbances in Heart Rhythm01:29

Disturbances in Heart Rhythm

3.0K
Arrhythmia or dysrhythmia refers to an abnormal heart rhythm caused by a defect in the heart's conduction system. It can cause the heart to beat irregularly, too quickly, or too slowly, leading to symptoms like chest pain, shortness of breath, and fainting. Factors such as stress, caffeine, alcohol, nicotine, cocaine, certain drugs, congenital defects, diseases, and electrolyte abnormalities can trigger arrhythmias.
Arrhythmias are categorized by their speed, rhythm, and origin. A slow heart...

ECG Interpretation of Rhythms01:24

ECG Interpretation of Rhythms

13.8K
An electrocardiogram (ECG)graphically represents the heart's electrical activity on ECG paper or a monitor.
Components of the Electrocardiogram
The primary components of a normal ECG waveform in Normal sinus rhythm(NSR) include the P wave, PR interval, QRS complex, ST segment, T wave, and occasionally a U wave.
ECG waveforms are divided by vertical and horizontal lines at standard intervals.
The horizontal axis measures time and rate, and the vertical axis measures amplitude or voltage....

Area of Science:

  • Neuroscience
  • Cognitive Science
  • Human-Computer Interaction

Background:

  • Brain-Computer Interfaces (BCIs) require effective user training methods.
  • Traditional feedback methods may not optimize user control for cognitive tasks.
  • Psychological learning principles can enhance BCI training.

Purpose of the Study:

  • To propose and evaluate an adapted feedback system using Skinner's shaping method for BCI control.
  • To improve user modulation of cognitive tasks like motor imagery and relaxation states.
  • To enhance overall BCI interaction perception and performance.

Main Methods:

  • Comparative study: standard feedback vs. shaping method (N=19).
  • Single-case study to assess continuous learning with the shaping method (N=5).
  • NASA Task Load Index (NASA-TLX) questionnaire used to measure user workload.

Main Results:

  • Significant interaction effects found for shaping method in performance and relax state tasks (p < .05).
  • Shaping procedure showed significant effects on Mental Demand, Performance, and Frustration in NASA-TLX (p < .05).
  • Continuous learning demonstrated an upward trend, particularly for the relax state task.

Conclusions:

  • The shaping procedure is effective in modulating brain rhythms for BCI control.
  • This method particularly improves cognitive tasks with higher initial difficulty.
  • The adapted feedback enhances user perception of BCI interaction and control.
