In the case of Autism Spectrum Disorder (ASD), much of the EEG related research has been through the use of different analytical methods to produce distinct biomarkers that reflect the core EEG differences between a healthy control and a patient with ASD. Several studies have shown a possible lead into quantitative electroencephalography, an analysis method in which EEG signals are differentiated into their frequency bands through the use of Fourier Analysis. Fourier Analysis is a mathematical transformation that decomposes functions depending on space or time into functions depending on spatial or temporal frequency. In simpler terms, it is a type of analysis that allows the identification of patterns and cycles in a timed series of data. Several key EEG profiles have been identified through Fourier Analysis such as the U-shaped pattern, in which the resting-state EEG from patients with ASD show excessive power from delta and theta frequency bands while alpha frequency bands are diminished [546]. This pattern reflects a distinct rhythm maturation when compared to healthy subjects, in which the standard observation is an age-related decrease in delta and theta power and an overall increase of alpha power [217, 129].
Cardiovascular and Other Illnesses Caused by Diesel Fuel Exhaust Emissions

Cruts et al. (2008) study the functional effect of DE exposure in the human brain in a paper with 81 citations. They exposed ten human volunteers to dilute DE (300 μg/m3) as a model for ambient PM exposure and FA for one hour using a double blind randomized crossover design. They monitored brain activity during and for one hour following each exposure using quantitative electroencephalography at eight different sites on the scalp. They found a significant increase in ‘median power frequency’ (MPF) in response to DE in the frontal cortex 30 minutes into exposure. The increase in MPF was primarily caused by an increase in fast wave activity (β2) and continued to rise during the one hour post-exposure interval. They conclude that there is a functional effect of DE exposure in the human brain, indicating a general cortical stress response.
Using brain waves to assess the colour effect on promoting spirituality in the mosque architecture
Published in Architectural Science Review, 2022
A sample size of 18 people has watched images prepared for the sample case through VR Box 2 sample virtual reality glass tool for 10s per image. Colour images have been broadcasted through the smart mobile phone in the glasses. This test has been performed sitting on a chair without disturbing sound and under normal conditions. Subsequently, by using a quantitative electroencephalography wave recorder device, brain waves were recorded in facing colour spectra and were investigated in the Profusion Study Manager or Compumedics nexus software, and finally, the results were presented at the end of the research. In this research, the thought recorder that had up to 19 channels and was made in Iran has been used. In the EEG system, the 10–20 standard system was used to replace and adjust the electrodes on the cap (Sadeghi Habibabad et al. 2019). All electrodes were also given with two reference ear electrodes. At the time of doing the test, the environmental conditions, including light and temperature, should be constant and as far as possible controlled for all samples.
