Spectral synchronicity in brain signals

Spectral Synchronicity in Brain Signals

Brain activity following stimulus presentation and during resting state are often the result of highly coordinated responses of large numbers of neurons both locally (within each region) and globally (across different brain regions). Coordinated activity of neurons can give rise to oscillations which are captured by electroencephalograms (EEG). Most studies on resting state are based on functio...

Mental Fatigue Assessment using recording Brain Signals: Electroencephalography

Background and Objectives: Mental fatigue is a condition triggered by prolonged cognitive activity. Mental fatigue causes brain over-activity. This is a condition where the brain cells become exhausted, hampering person productivity, and overall cognitive function. The aim of this study was to assess students’ mental fatigue using brain indices. Methods: The present descriptive - analytic stud...

Evaluating Spectral Signals to Identify Spectral Error

Since the precision and accuracy level of a chemometric model is highly influenced by the quality of the raw spectral data, it is very important to evaluate the recorded spectra and describe the erroneous regions before qualitative and quantitative analyses or detailed band assignment. This paper provides a collection of basic spectral analytical procedures and demonstrates their applicability ...

Transcribed in synchronicity

But the discrete clocks can work as one because they are synchronized by electrical impulses. Our internal clock, which controls circadian behaviors and physiology, is a circuitry of many thousands of neurons in the brain called the suprachiasmatic nucleus (SCN). The Kobe group looked at communication within this circuitry in cultured brain slices of transgenic mice using a fluorescent reporter...
