Electroencephalography-Based Neuroemotional Responses in Cognitively Normal and Cognitively Impaired Elderly by Watching the Ardisia mamillata Hance with Fruits and without Fruits

Abstract

Background: The purpose of this study is to explore the difference between the indexes of neuro-emotion between the cognitively normal elderly (CNE) and cognitively impaired elderly (CIE) while viewing the Ardisia mamillata Hance with red fruit (F) and without red fruit (NF) to determine which kind of the Ardisia mamillata Hance would be more beneficial to the participants’ neuro-emotions. Methods: Nine CNE individuals and nine CIE individuals, ranging in age from 80–90 years old, participated in this study and signed the informed consent form before beginning the experiment. Six mood indicators (engagement, excitement, focus, interest, relaxation, and stress) were measured by an EEG headset during the participants’ viewing of the NF, F, and NF + F. Results: For the CNE group, their engagement, excitement, and focus values were the lowest, while their interest value was the highest when they view the NF + F; therefore, we obtain the results that the combination of NF + F was the most beneficial to their EEG emotions. For the CIE group, the combination of NF + F increased their interest score, but decreased their focus score, which indicated that the NF + F was the most beneficial to their neuro-emotions. Conclusions: This study concluded that the combination of plants with and without fruits was most beneficial to the neural emotions of both groups of elderly people. Especially for the CIE, plants with larger and warmer colors, such as yellow, red, and orange fruits, should be considered for installation indoors or outdoors, as this would be better for their emotional well-being.

Which horticultural activities are more effective for children’s recovery from stress and mental fatigue? A quasi-experimental study

“…Aside from longitudinal studies, research has also explored the immediate health effects of engaging in a single horticultural activity, typically lasting for 3-20 min (Hassan et al, 2018(Hassan et al, , 2019b. Although horticultural activity has been shown to alleviate stress, sadness, anxiety, and other negative emotions in different groups, studies have also reported some inconsistencies (Du et al, 2022). Furthermore, there is a clear gap in research regarding the effects of these interventions on children, indicating the need for empirical studies determining the efficacy of horticultural interventions in aiding children's recovery from psychological and physiological stress.…”

A Study of Brain Function Characteristics of Service Members at High Risk for Accidents in the Military

“…In a resting EEG with eyes closed, natural oscillations reflecting an idle cortical state become dominant, with the dominant peak frequency typically located in the 4–13 Hz band. Previous reports have observed that the dominant oscillation frequency, which typically appears in the alpha band during normal aging, is lower in patients with cognitive impairment [ 37 , 38 , 39 , 40 ].…”
