Aim:Regarding the problems of people with ADHD and attention deficit hyperactivity disorder and its importance in the quality of social relationships, the present study was conducted to investigate the effect of neurofeedback therapy on improvement of eye emotion recognition. Method: For this purpose, 24 adults including 12 males and 12 females between the ages of 19 to 25 years were selected and divided into experimental and control groups. The subjects were evaluated by an adult ADHD test and interview, and provided that no other symptoms of mental disorders were measured by the SCL-90 test. All subjects were recorded electroencephalographically and all responded to eye emotion recognition test. The experimental group also participated in 15 sessions of neurofeedback treatment and then both groups were re-evaluated. Results: The results showed that the experimental group performed better than the control group after the neurofeedback sessions and the difference between them was significant. Conclusion: According to the findings of this study, it can be concluded that individuals' performance in emotion recognition is not limited to classical mirror neurons and emotional processing takes place in areas beyond what is known as mirror neurons.

Aim:The purpose of this study was to determine the effects of video and live observation on activation of mirror neurons in football keep- up skill. Metod:Twenty-four students (mean age: 17.66 0.816 years) who have taken part in Olympiads competition, voluntarily participated ad yoked into live and video observation. Participants’ brain waves were recorded by EEG in open eye resting and observing live and video observation conditions. Mu rhythm Suppression, as the mirror neuron activation, was calculated as a ratio of the alpha absolute power during observation of video and live models relative to the alpha absolute power in the baseline condition (rest) Findings:Results showed that there were no significant differences in mu rhythm suppression between live and video observation groups in C3, Cz and C4 brain areas. In addition, absolute alpha power was suppressed significantly in observation conditions compared to rest. Conclusion: Regarding the activation of mirror neurons in both live and video observation, our result suggested that in the case of limitation in the use of the live model, video model can be used in soccer keep- up skill.

Introduction: The purpose of this research was to study the effect of Rhythmic melodic stimuli and playing on the performance of spatial neurons and the working memory of children aged 4-7 years.Methods: Materials and Methods: This research was a semi-experimental study with pre-post and post-prognosis in two educational groups. The survey population included all children aged 4-7 years old in Tehran's 8th district. The sampling method was available in this study and the sample size was 20 people, 10 of them in the music group and 10 in the game group with random sampling. Data collection was based on the Conner's parent and teacher questionnaire, working memory Wechsler 4, and brain recording from frontal region in three modes (1. rest eye open,2. Kohs Block test,3. Imitation of the game) Analysis and analysis of data obtained using SPSS version 24 and two descriptive and inferential sections using the Klomof-Samsinom assay for normal distribution of scores Multivariate analysis of MANOVA was performed. Findings: The results of this study showed that learning music and playing, in reducing the symptoms of hyperactive children and the performance of 4-7 years old neurons is 1/92% and 5.68% effective. Conclusion: Learning games with rules and music are effective tools in improving the performance and reducing the symptoms mirror neurons in 4-7 years old hyperactive children.

Aim: The objective is to examine the association between mirror neurons activity and electrical activity of muscles in social-comparative video feedback of young females’ golf putting. Methods: 18 non-athletic females from University, are randomly assigned to 3 groups namely, positive, negative and real social-comparative video feedback. In the first day, golf putting is taught and 6 trials of golf putt are considered as pre-test. The second day includes 60 putts with 5-minute rest between trials and receiving relevant video feedback for each group and after each set of trial which constitute the acquisition session. The third day consists of 6 trials collectively considered as retention test. Using the two EEG and EMG sensors, the information are recorded in three baseline, execution and observation conditions. In the last trial of acquisition period, the levels of electrical activity of muscle and brain are recorded in baseline condition, condition of observing feedback films and concurrent with putting. For analysis, Pearson correlation coefficient is used to examine the association between level of electrical activity of brain and biceps brachial muscle (pResult & Conclusion: The results suggest that there is a significantly positive association between electrical activity of muscle and mirror neurons during execution.

Introduction: Mental imagery is an important skill that athletes should always work on and apply with high confidence; especially during competition in order to relieve stress and improve performance. The aim of this study was to investigate the role of mirror neuron on different speeds of mental imagery on basketball dribbling performance. Methods: The research method was semi-empirical and a pretest-posttest design was used. The participants were 30 female students (average age 22± 1.12) selected through a purposive sampling method and categorized in three groups of rapid-speed, equal-speed, and low-speed imagery. Following the basketball dribble function in pretests, the participants were involved in imagery for a period of four consecutive days, and were subsequently tested for the real dribble function in the posttests. They were also subjected to electroencephalographic assessment during imagery, focusing primarily on the reaction of the mirror neurons within the process. The findings were then analyzed using the intragroup analysis of variance. Findings: The results showed that dribble function in all groups improved (p≤0.05). However, investigation of the effect size indicated a significant improvement in the groups with slow-speed and equal-speed imagery compared to those receiving high-speed imagery. Mu rhythm suppression in areas C4 and Cz were observed in all groups (p≤0.05). C3 area was active only in slow-speed group. Conclusions: Mental imagery causes required movements encoding for performing skill in the brain by activating mirror neurons. In brain, this movement encoding leads to facilitation in motor skills.

Introduction: Emotional eavesdropping is information that observer receives by listening and watching emotional reactions directed by third party (as coach) to another (model). It seems mirror neurons system is one mechanism responsible for this but ways in which emotional eavesdropping discharges this neurons are not clear. So the aim of this study was to investigate the effect of emotional eavesdropping of model on mirror neurons activity (mu rhythm suppression). Methods: For this reason, 22 right hand novice athletes (average age 20/69±1/10) participate voluntary in this research. These participants observed three instructional video of free throw in basketball that also display emotional reactions (positive, neutral, negative) of coach and model about model performance. Four Brain waves records were done by electroencephalographic assessments: one base record with open eyes as index of mirror neurons activity in rest and three records during positive, neutral and negative emotional eavesdropping in three regions C3, C4 and Cz. Findings: 3×3 within subjects ANOVA findings demonstrated that mu rhythm suppressed during three emotional eavesdropping in three central regions. Post hoc results showed more significant mu rhythm suppression during negative emotional eavesdropping in C4 than other conditions. Conclusion: thus, these findings confirm valance hypothesis about negative emotion and right hemisphere hypothesis and it seems emotional eavesdropping modulate mirror neurons activity.
