Abstract
Emotion regulation is crucial in daily life, and transcranial alternating current stimulation (tACS) has the potential to improve it by modulating neural oscillations. In this study, 101 healthy adults were randomized into four groups: frontal theta tACS, frontal alpha tACS, parieto-occipital alpha tACS, and sham control. Participants completed emotion regulation and facial Stroop tasks during stimulation, with emotional states assessed using the Positive and Negative Affect Scale (PANAS) and the Profile of Mood States-Short Form (POMS-SF) before and after stimulation. Physiological signals were also recorded during the stimulation. Repeated measures ANOVA analyzes were used for pre/post scale scores, task performance and physiological features. Results indicated that frontal theta tACS reduced negative emotions and improved reappraisal ability, whereas parieto-occipital alpha tACS showed comparable but non-significant effect. In contrast, frontal alpha tACS increased negative emotions and reaction times to disgust faces. These findings suggest that frontal theta tACS is a promising protocol for improving emotion regulation, and tACS may serve as a valuable tool for exploring neural mechanisms underlying emotional disorders.

期刊介绍：
Cognitive Neurodynamics provides a unique forum of communication and cooperation for scientists and engineers working in the field of cognitive neurodynamics, intelligent science and applications, bridging the gap between theory and application, without any preference for pure theoretical, experimental or computational models.
The emphasis is to publish original models of cognitive neurodynamics, novel computational theories and experimental results. In particular, intelligent science inspired by cognitive neuroscience and neurodynamics is also very welcome.
The scope of Cognitive Neurodynamics covers cognitive neuroscience, neural computation based on dynamics, computer science, intelligent science as well as their interdisciplinary applications in the natural and engineering sciences. Papers that are appropriate for non-specialist readers are encouraged.
1. There is no page limit for manuscripts submitted to Cognitive Neurodynamics. Research papers should clearly represent an important advance of especially broad interest to researchers and technologists in neuroscience, biophysics, BCI, neural computer and intelligent robotics.
2. Cognitive Neurodynamics also welcomes brief communications: short papers reporting results that are of genuinely broad interest but that for one reason and another do not make a sufficiently complete story to justify a full article publication. Brief Communications should consist of approximately four manuscript pages.
3. Cognitive Neurodynamics publishes review articles in which a specific field is reviewed through an exhaustive literature survey. There are no restrictions on the number of pages. Review articles are usually invited, but submitted reviews will also be considered.
