![]() "Our findings suggest that fatigue significantly affected individuals' LPP amplitudes in the early, mid, and late windows in the Non-mindfulness group, specifically, the more fatigued individuals had lower LPP amplitudes, but not in the Mindfulness group." "LPP is an important indicator of emotional stimuli perceived by individuals, and positive or negative pictures can induce an increase in LPP amplitude more than neutral pictures," Fan, Li and their colleagues wrote. They specifically looked at late positive potential, or LPP, a neural indicator of intense or heightened attention to emotional stimuli, which can offer insight about the processing of emotions while exposed to positive or negative stimuli. The researchers ultimately analyzed the data they collected to determine whether the mindfulness meditation practice had affected the participants' emotional state, as well as ERPs in their brain. All the participants were all asked to rate their level of fatigue and emotional state both before and after the experiment. Subsequently, all the participants completed a simple image processing task, where they were presented with different photographs on the screen while electrodes placed behind their ear recorded ERPs. During these 15 minutes, people in the second group simply rested with their eyes closed. ![]() Participants in the first group completed a 15-minute guided mindfulness meditation, during which they were asked to pay attention to their breathing and to different body parts. In their experiment, Fan, Li and their colleagues recorded the ERPs of 145 participants who were randomly assigned to one of two groups. Measuring these voltages can help neuroscientists and psychology researchers to better understand peoples emotional and physiological responses to different experiences in everyday settings. This study examined whether mindfulness meditation affects the association between fatigue and emotions, using event-related potentials (ERPs)."Įvent-related potentials (ERPs) are tiny electrical voltages generated in the brain in response to specific events or stimuli, such as seeing someone or something, hearing a specific sound, and so on. "However, if individuals continue to be affected by negative emotions when they are fatigued, it is unclear whether mindfulness can buffer the negative association between fatigue and emotions. "In previous research, mindfulness meditation reduced the intensity of negative emotional stimuli," Jialin Fan, Wenjing Li and their colleagues wrote in their paper published in Frontiers in Behavioral Neuroscience. Researchers at Shenzhen University in China recently set out to investigate whether mindfulness practices could also help to alleviate the adverse effects of fatigue on emotional processing. Research findings suggest that mindfulness meditation, which focus on being present in the moment and observing the breath, along with passing feelings, emotions, and sensations, can help to reduce the intensity of negative feelings, facilitating the healthy processing of emotions. This can in turn impair their ability to process emotions throughout the day. We discover that the Fe–Co dual sites embedded in N-doped porous carbon are beneficial for the activation of oxygen by weakening the O O bonds.Past studies suggest that irrespective of its causes, fatigue can intensify negative emotions, making affected people feel more overwhelmed and reducing their positive feelings. In addition, the power density and the specific energy density reach 260 mW cm −2 and 870 W h kg Zn −1. ![]() Furthermore, when employed as a cathode catalyst in a Zn–air battery, the (Fe,Co)/CNT exhibits high voltages of 1.31 V and 1.23 V at discharge current densities of 20 mA cm −2 and 50 mA cm −2, respectively. The ORR test reveals that the performance of the (Fe,Co)/CNT is superior to most of the reported non-precious catalysts in alkaline electrolytes. 0.842 V), outperforming those of the commercial Pt/C. The electrocatalyst shows state-of-the-art ORR performance with an admirable onset potential ( E onset, 1.15 V vs. ![]() Herein, we construct a novel electrocatalyst with Fe–Co dual sites embedded in N-doped carbon nanotubes ((Fe,Co)/CNT), which exhibits inimitable advantages towards the oxygen reduction reaction. ![]()
