Data_Sheet_1_Influence of monaural auditory stimulation combined with music on brain activity.ZIP
No full textIntroductionRecently, the increasing attention to mental states and psychophysical health has fueled the research into methods that can aid in relaxation and recovery. Traditional methods like meditation and sauna, while effective, have their limitations; thus, the need for more accessible and convenient alternatives.MethodsOur innovative approach combines monaural beats with music, attempting to replicate the relaxing effects of a sauna in the auditory domain.ResultsIn comparison to normal music and silent condition, the power of the theta active band significantly increased when listening to our modified music. Furthermore, after listening to modified music, there was a significant increase in mismatch negativity (MMN) amplitude in the oddball task. Additionally, participants’ subjective responses to a questionnaire indicated significant changes in body relaxation and other metrics after listening to the processed music.DiscussionThis state is considered similar to the “totonou” state, which manifests in physical and mental feelings of relaxation, pleasure, and mental clarity in the sauna. Thus, the present research proposes a convenient method for achieving relaxation, opening an avenue for individuals to customize their “totonou” music based on personal preferences.</p
Data_Sheet_1_Gamma music: a new acoustic stimulus for gamma-frequency auditory steady-state response.ZIP
No full textA frequency range exceeding approximately 30 Hz, denoted as the gamma frequency range, is associated with various cognitive functions, consciousness, sensory integration, short-term memory, working memory, encoding and maintenance of episodic memory, and retrieval processes. In this study, we proposed a new form of gamma stimulation, called gamma music, combining 40 Hz auditory stimuli and music. This gamma music consists of drums, bass, and keyboard sounds, each containing a 40 Hz frequency oscillation. Since 40 Hz stimuli are known to induce an auditory steady-state response (ASSR), we used the 40 Hz power and phase locking index (PLI) as indices of neural activity during sound stimulation. We also recorded subjective ratings of each sound through a questionnaire using a visual analog scale. The gamma music, gamma drums, gamma bass, and gamma keyboard sounds showed significantly higher values in 40 Hz power and PLI compared to the control music without a 40 Hz oscillation. Particularly, the gamma keyboard sound showed a potential to induce strong ASSR, showing high values in these indices. In the subjective ratings, the gamma music, especially the gamma keyboard sound, received more relaxed, comfortable, preferred, pleasant, and natural impressions compared to the control music with conventional gamma stimulation. These results indicate that our proposed gamma music has potential as a new method for inducing ASSR. Particularly, the gamma keyboard sound proved to be an effective acoustic source for inducing a strong ASSR while preserving the comfortable and pleasant sensation of listening to music. Our developed gamma music, characterized by its pleasantness to the human ear, offers a significant advantage for the long-term use of gamma stimulation. The utilization of this music could potentially reduce the physical and psychological burden on participants compared to conventional 40 Hz stimuli. This music is not only expected to contribute to fundamental neuroscience research utilizing ASSR but also to facilitate the implementation of gamma music-based interventions aimed at enhancing human cognitive functions in everyday life.</p

Effects of oxygen-radical pretreatment on MCC hydrolysis by cellulolytic enzymes in culture supernatant. Reducing sugars released from (a) oxygen-gas- or (b) oxygen-radical-pretreated MCC by enzymatic hydrolysis using culture supernatant were assayed using the DNS method. Error bars represent the mean ¹ standard error of the mean of three independent experiments. Figure S2. Gas chromatography spectra of the washing water of oxygen-gas- and oxygen-radical-pretreated wheat straw. (a) Oxygen-gas- and (b) oxygen-radical-pretreated wheat-straw samples were extracted with water to wash out enzyme inhibitors. Each treatment sample was washed with 25°C Milli-Q water, followed lyophilization, trimethylsilylation, and analysis of the liquid fraction by gas chromatography. Figure S3. Reducing-sugar production from washed and unwashed oxygen-radical-pretreated wheat straw. Reducing sugars released from washed and unwashed oxygen-radical-pretreated wheat straw after enzymatic hydrolysis using the supernatant from Phanerochaete chrysosporium cultures were assayed using the DNS method. Data are presented as the mean ¹ standard deviation of three experiments
