“…However, creativity is only enhanced by moderate noise levels given that very high noise levels attenuate information processing. Neural studies have examined the oscillatory activities induced by sound of white noise (a random signal having equal intensity at different frequencies, such as sound of a non-existent radio station), with two studies reporting significantly decreased alpha rhythm (Horii et al, 2004;Kawasaki et al, 2009). These authors suggested that white noise induces unpleasant feeling, which decreases alpha powers.…”

“…however, the underlying causal mechanisms remain unclear. Some studies have reported environmental effects on neural oscillation at the alpha band (8-12 Hz) (Horii et al, 2004;Kawasaki et al, 2009;Yao et al, 2009;Yoto et al, 2007) and DMN (Rondinoni et al, 2011;2013), which is a critical neural function and network for creativity (Dietrich & Kanso, 2010;Fink et al, 2006Fink et al, , 2009Lustenberger et al, 2015;Schwab et al, 2014). Yoto and colleagues indicated that different stimuli have different effects on the mental state (e.g., anxiety or calmness), which modulate neural processing (Yoto et al, 2007).…”

Human creativity refers to the cognitive capacity to produce new and valuable information, which often leads to innovations in society and scientific technology. Over a long period of time, many people have been fascinated by the question of how creativity emerges in our brain and how it can be enhanced. Recently, a growing number of studies have revealed that some types of environmental stimuli can enhance human creativity. Further, specific temporal dynamics of cognitive processes are crucial for acquiring creative ideas. However, how the temporal dynamics of creativity are influenced by the environment remains unclear. Through a literature review of neural and psychological research, this study aimed to elucidate the environmental settings that enhance cognitive performance. We found that each stage of the temporal dynamics of creativity may differently be correlated with neural function. Further, environmental factors may have various, and sometimes contrasting, effects on the temporal dynamics of creativity. We propose a hypothesis that the optimal environment condition varies depending on the stages of temporal dynamics since each stage requires different cognitive processes. However, there is a need for future studies to elucidate how creativity is modulated by social conditions and the physical environment, as well as whether there are differences in the ideal environment for individual and group creativities. Nonetheless, this is the first study to clarify the influence of environmental settings on the temporal dynamics of creativity from the perspective of neuroscience and psychology.

“…Iwaki et al [34] showed an increase in alpha band amplitude with music stimulation, while Kawasaki et al . [35] clarified that music-induced pleasure increases the intensity of the alpha waves. Many reports have indicated that the production of alpha waves is increased by relaxation.…”

Physiological anthropology presently covers a very broad range of human knowledge and engineering technologies. This study reviews scientific inconsistencies within a variety of areas: sitting posture; negative air ions; oxygen inhalation; alpha brain waves induced by music and ultrasound; 1/f fluctuations; the evaluation of feelings using surface electroencephalography; Kansei; universal design; and anti-stress issues. We found that the inconsistencies within these areas indicate the importance of integrative thinking and the need to maintain the perspective on the biological benefit to humanity. Analytical science divides human physiological functions into discrete details, although individuals comprise a unified collection of whole-body functions. Such disparate considerations contribute to the misunderstanding of physiological functions and the misevaluation of positive and negative values for humankind. Research related to human health will, in future, depend on the concept of maintaining physiological functions based on consistent science and on sustaining human health to maintain biological welfare in future generations.

“…Extensive research in the field of affective brain mapping has been published on characterising EEG variations during distinct emotion elicitations using Power Spectral Density (PSD) (Kawasaki et al, 2009;Chanel et al, 2011;Gandhi et al, 2011;Wang et al, 2011;Jatupaiboon et al, 2013), Common Spatial Patterns (CSP) (Li and Lu, 2009;Fattahi et al, 2013), Fast Fourier Transform (FFT) analysis (Yoon and Chung, 2013), entropy analysis (Hosseini, 2011;Khalilzadeh et al, 2010;Srinivasan et al, 2007), Higher Order Crossing (HOC) analysis (Petrantonakis and Hadjileontiadis, 2010a; Petrantonakis and Hadjileontiadis, 2010b), third-order spectral analysis (Hosseini et al, 2010;Hosseini, 2012) and statistical analysis (Takahashi and Tsukaguchi, 2004;Yuen et al, 2013) techniques. Current research findings reveal that PSD is an established technique for EEG signal analysis in the frequency domain (Dressler et al, 2004).…”

Development of affective Brain-Computer Interfaces (BCIs) via Electroencephalogram (EEG) has emerged as a cynosure of research in early diagnosis and effective management of depression. However, conventional BCIs are still lacking in terms of high computational complexity, less accuracy due to Fourier phase suppression and lack of substantial conclusion for depression diagnosis. An automated, EEG-based depression diagnostic and management tool is proposed to overcome these limitations. Channel eventrelated potentials, cross-coherence and power spectra plots in MATLAB are quantified and studied as an outcome to map real-time, emotion-specific multichannel EEG data set into distinct emotional states. A fast and stable fourth-order statistics-based independent component analysis is incorporated to reject temporal/spatial artefacts. Increases in frontal alpha (8-13 Hz) and delta (0.5-4 Hz) power/coherence are during depressed and normal/relaxed states, respectively. Devotional music (relaxed state) is found to facilitate depression elimination. Results are found to be statistically significant across all subjects with minimal p-values. Hence, it has been inferred that the proposed model has the potential to aid early and accurate depression diagnostic and management process.
