Effects of stimulation by three-dimensional natural images on prefrontal cortex and autonomic nerve activity: a comparison with stimulation using two-dimensional images
TLDR
Visual stimulation by realistic 3D floral images promotes physiological relaxation more effectively than the corresponding 2D image.Abstract:
Empirical evidence suggests that three-dimensional (3D) images of nature promote physiological relaxation in humans by providing more realistic effects compared with two-dimensional (2D) images However, no studies have evaluated the physiological relaxation effects of nature-derived 3D images on prefrontal cortex and autonomic nerve activity The present study aimed to clarify the physiological relaxation effects of visual stimulation by 3D flower images on prefrontal cortex and autonomic nerve activity Nineteen male university students (222 ± 06 years) were presented with 3D and 2D images of the water lily for 90 s Prefrontal cortex activity was measured using near-infrared spectroscopy, while autonomic nerve activity was measured using heart rate variability (HRV) Psychological effects were determined using a modified semantic differential method (SD) Compared with visual stimulation by 2D images, that by 3D images resulted in a significant decrease in oxyhemoglobin concentration in the right prefrontal cortex, lower sympathetic activity as calculated by the ratio of the low-frequency to high-frequency HRV component, and a significantly greater realistic feeling as evidenced by higher SD ratings In conclusion, visual stimulation by realistic 3D floral images promotes physiological relaxation more effectively than the corresponding 2D imageread more

Natural environments and mental health
Annemarie Mantler,Alan C. Logan +1 more
TL;DR: This synthesis includes research from various branches of science and medicine, e.g., epidemiology, psychology, physiology, anthropology, evolutionary biology, and microbiology, that makes it difficult to dismiss the clinical relevancy of natural environments in 21st century mental health care.

Natural environments, ancestral diets, and microbial ecology: is there a modern “paleo-deficit disorder”? Part I
TL;DR: It is argued, as Dubos did 40 years ago, that researchers should more closely examine the relevancy of silo-sequestered, reductionist findings in the larger picture of human quality of life.

Brain activity, underlying mood and the environment: A systematic review
Michael Francis Norwood,Ali Lakhani,Annick Maujean,Heidi Zeeman,Olivia Creux,Elizabeth Kendall +5 more
TL;DR: In this article, a review explores how different environments affect brain activity and associated mood response and suggests that the realism of an experimental condition, and therefore validity of participant responses, is greater when more senses are engaged.

The Measurement of Meaning
TL;DR: In this article, the authors deal with the nature and theory of meaning and present a new, objective method for its measurement which they call the semantic differential, which can be adapted to a wide variety of problems in such areas as clinical psychology, social psychology, linguistics, mass communications, esthetics, and political science.

TL;DR: The spontaneous beat-to-beat oscillation in R-R interval during control recumbent position, 90° upright tilt, controlled respiration and acute and chronic β-adrenergic receptor blockade was analyzed, indicating that sympathetic nerves to the heart are instrumental in the genesis of low-frequency oscillations in R -R interval.

TL;DR: Dynamic, physiological regulation of CBF by a mechanism (neuronal or biochemical) dependent on neuronal firing per se, but independent of the cerebral metabolic rate of oxygen, is hypothesized.
