“…Contact with plants increases alpha waves, reduces stress ( Hassan, 2018 ), and induces relaxation ( Jeong and Park, 2021 ). As the number of plants increases, negative emotions gradually decrease, and the low-frequency band of the EEG relaxation band increases ( Jung et al, 2023 ). Previous research has also indicated that viewing nature-related landscape elements, such as bamboo forests ( Hassan et al, 2018 ) and lawns ( Wang, 2019 ), is positively correlated with emotional restoration.…”

Previous research has indicated that natural landscapes exhibit a greater capacity for ameliorating negative emotional states in individuals when compared to urban landscapes. Nevertheless, significant scientific inquiries, such as the uniformity of the rejuvenating effect across distinct categories of natural landscapes on college students and the choice of the optimal plant community for achieving the most potent restorative effect, remain unexplored. This study aimed to address these questions by selecting four plant communities (single-layer grassland, single-layer woodland, tree-grass composite woodland, tree-shrub-grass composite woodland) and using an electroencephalography method to capture the neuroelectric activity of the participants in combination with the Positive and Negative Affect Schedule score to explore the effects of plant community types on emotional recovery. The results showed that all four plant communities significantly increased positive emotions and significantly reduced negative emotions. There was no significant difference in the recovery effect of positive emotions among the four plant community types, but there was a significant difference in the recovery effect of negative emotions. The effect of tree-shrub-grass composite woodland on the negative emotion recovery effect is the best; the EEG results found that the alpha wave amplitude induced by the tree-shrub-grass composite woodland was significantly higher than that of the other three groups of plant communities, and the EEG and behavioral results were consistent. The results show that the tree-shrub-grass composite woodland has the best restoration effect and has stronger planning and design significance.

“…In recent years, a growing body of scholarship that empirically examines neurophysiological responses to the built environment has begun to emerge [1,2]. These studies provide evidence that visual exposure to biophilic design features, or spatial designs that either integrate live organic material or imitate patterns found in nature (biophilic design [3]), may reduce physiological stress, a biological response wherein the body's systems undergo changes to cope with perceived threats or challenges [4][5][6][7][8][9][10][11]. Whilst the impact of this emerging research on our understanding of the relationship between the built environment and neurophysiological responses, such as physiological stress, is considerable, when viewed in conjunction with emerging evidence in relation to neuroimmunology, these findings may be of greater significance than previously understood.…”

Recent research in architectural neuroscience has found that visual exposure to biophilic design may help reduce occupant physiological stress responses. However, there are still significant gaps in our understanding of the complex ways in which biophilic design impacts on building occupant neurophysiology. The relationship between visual exposure to biophilic design and neurophysiological responses such as neuroinflammation have yet to be directly investigated. This paper examines the results of a pilot study that was established to investigate the relationship between visual exposure to biophilic design and neuroinflammation, as mediated by physiological stress responses. The pilot study utilised a 32-channel quantitative electroencephalograph (qEEG) to assess the relative changes in neuroinflammatory markers (relative alpha and relative delta power band activity) of 10 participants while they were exposed to 2D digital images of buildings that visually expressed varying degrees of biophilic design. Participants exhibited a decrease in relative delta power when exposed to higher levels of biophilic design. No statistically significant changes in relative alpha power were observed. These findings suggest that exposure to buildings with higher degrees of biophilia may result in decreased neuroinflammatory activity. In doing so, this research works to further develop our understanding of the complex ways in which the built environment impacts on occupant neuroinflammation and physiological stress.

Emotion is the research subject of many disciplines. Among these studies, emotion emerges as a concept related to biophilic design. The present investigation used bibliometric analysis, which included documents from the Scopus and Web of Science Core Collection stores of data to the science mapping approach in the VOSviewer. Considering the analysis’ findings, it can be said that the examination of emotion at the intersection of biophilic and design under the heading the concept of architecture is a field of study that is new, open to examination, and open to association with different concepts.
