Summary
Artifact-corrected neurofeedback (NF) significantly improved auditory and visual attention in college students by reducing theta/beta power ratios (TBPR). Non-artifact-corrected NF showed only minor improvements in visual attention.
Area of Science:
- Neuroscience
- Cognitive Psychology
Background:
- Electromyographical (EMG) artifacts frequently contaminate electroencephalographical (EEG) signals.
- Artifacts can potentially impact the efficacy of neurofeedback (NF) training.
Purpose of the Study:
- To investigate the impact of artifact correction on neurofeedback training outcomes.
- To compare the effects of artifact-corrected (AC) versus non-artifact-corrected (NAC) NF on attention and brainwave activity.
Main Methods:
- A double-blind study involving 14 unmedicated college students randomly assigned to AC-NF or NAC-NF groups.
- Both groups underwent 12 sessions of NF, targeting theta/beta power ratios (TBPR) reduction.
- Continuous performance tests were used to assess auditory and visual attention.
Main Results:
- The AC-NF group demonstrated significant improvements in both auditory and visual attention.
- The NAC-NF group showed significant gains only in visual attention.
- Only the AC-NF group successfully reduced their theta/beta power ratios (TBPR).
Conclusions:
- Artifact correction plays a crucial role in enhancing neurofeedback training efficacy.
- AC-NF leads to greater improvements in auditory and visual attention compared to NAC-NF.
- Further research is needed to validate these findings.

01:21Pilot and Numeric Relaying
496
Pilot relaying is a type of differential protection used in power systems. It compares electrical quantities at the terminals of equipment via a communication channel instead of direct relay interconnection. This method is essential for transmission lines where the terminals are far apart, typically up to 80 km for lines with 69 to 115 kV ratings. Four types of communication channels are used for pilot relaying:

01:15Distance Corrections
301
To achieve precise distance measurements, especially in surveying and construction, certain corrections must be applied to account for potential sources of error like the standardization errors, temperature variations, and slope adjustments.Standardization error emerges when measurement equipment undergoes changes, such as wear, repairs, or weather impacts. To address this, surveyors compare the equipment’s readings to a standard. This process identifies any deviation that might lead to...

01:20Power Factor Correction
557
The power transmission to a factory involves the transfer of apparent power, a combination of active and reactive power. The power factor measures how effectively electrical power is converted into useful work output. The ratio of the real power (KW) that does the work to the apparent power (KVA) supplied to the circuit.

01:14NMR Spectrometers: Resolution and Error Correction
1.1K
When magnetic nuclei in a sample achieve resonance and undergo relaxation, the signal detected in NMR is an approximately exponential free induction decay. Fourier transform of an exponential decay yields a Lorentzian peak in the frequency domain. Lorentzian peaks in an NMR spectrum are defined by their amplitude, full width at half maximum, and position, where the peak width is governed by the spin-spin relaxation time alone. In real experiments, however, the applied magnetic field is rendered...

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...

01:15Nursing Evaluation
4.4K
The evaluation stage signals the end of the nursing process. The nurse gathers evaluative data to assess whether or not the patient has attained the expected results. Whereas the nurse collects data in the nursing assessment to identify the patient's health concerns, the evaluation stage data determines if the indicated health issues are resolved. Evaluative data collection includes two sections: the data acquired to evaluate patient outcomes and the time criteria for data collection.
