[PMID: 37715469 PMCID: PMC10629897 DOI: 10.1093/cercor/bhad324] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2023] [Revised: 08/17/2023] [Accepted: 08/18/2023] [Indexed: 09/17/2023] Open
Abstract
Previous studies have reported relationships between exercise and pain. However, little is known about how aggressive exercise modulates individuals' responses to their own and others' pain. This present study addresses this question by conducting 2 studies employing event-related potential (ERP). Study 1 included 38 participants whose self-perceived pain was assessed after intervention with aggressive or nonaggressive exercises. Study 2 recruited 36 participants whose responses to others' pain were assessed after intervention with aggressive or nonaggressive exercise. Study 1's results showed that P2 amplitudes were smaller, reaction times were longer, and participants' judgments were less accurate in response to self-perceived pain stimuli, especially to high-pain stimuli, after intervention with aggressive exercise compared to nonaggressive exercise. Results of study 2 showed that both P3 and LPP amplitudes to others' pain were larger after intervention with aggressive exercise than with nonaggressive exercise. These results suggest that aggressive exercise decreases individuals' self-perceived pain and increases their empathic responses to others' pain.

Cui Y, Cong F, Huang F, Zeng M, Yan R. Cortical activation of neuromuscular electrical stimulation synchronized mirror neuron rehabilitation strategies: an fNIRS study. Front Neurol 2023; 14:1232436. [PMID: 37602262 PMCID: PMC10437114 DOI: 10.3389/fneur.2023.1232436] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2023] [Accepted: 07/24/2023] [Indexed: 08/22/2023] Open
Abstract
Background The mirror neuron system (MNS) plays a key role in the neural mechanism underlying motor learning and neural plasticity. Action observation (AO), action execution (AE), and a combination of both, known as action imitation (AI), are the most commonly used rehabilitation strategies based on MNS. It is possible to enhance the cortical activation area and amplitude by combining traditional neuromuscular electrical stimulation (NMES) with other top-down and active rehabilitation strategies based on the MNS theory. Objective This study aimed to explore the cortical activation patterns induced by NMES synchronized with rehabilitation strategies based on MNS, namely NMES+AO, NMES+AE, and NMES+AI. In addition, the study aimed to assess the feasibility of these three novel rehabilitative treatments in order to provide insights and evidence for the design, implementation, and application of brain-computer interfaces. Methods A total of 70 healthy adults were recruited from July 2022 to February 2023, and 66 of them were finally included in the analysis. The cortical activation patterns during NMES+AO, NMES+AE, and NMES+AI were detected using the functional Near-Infrared Spectroscopy (fNIRS) technique. The action to be observed, executed, or imitated was right wrist and hand extension, and two square-shaped NMES electrodes were placed on the right extensor digitorum communis. A block design was adopted to evaluate the activation intensity of the left MNS brain regions. Results General linear model results showed that compared with the control condition, the number of channels significantly activated (PFDR < 0.05) in the NMES+AO, NMES+AE, and NMES+AI conditions were 3, 9, and 9, respectively. Region of interest (ROI) analysis showed that 2 ROIs were significantly activated (PFDR < 0.05) in the NMES+AO condition, including BA6 and BA44; 5 ROIs were significantly activated in the NMES+AE condition, including BA6, BA40, BA44, BA45, and BA46; and 6 ROIs were significantly activated in the NMES+AI condition, including BA6, BA7, BA40, BA44, BA45, and BA46. Conclusion The MNS was activated during neuromuscular electrical stimulation combined with an AO, AE, and AI intervention. The synchronous application of NMES and mirror neuron rehabilitation strategies is feasible in clinical rehabilitation. The fNIRS signal patterns observed in this study could be used to develop brain-computer interface and neurofeedback therapy rehabilitation devices.

Physiol Behav 2022; 255:113930. [PMID: 35905808 DOI: 10.1016/j.physbeh.2022.113930] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2022] [Revised: 07/21/2022] [Accepted: 07/24/2022] [Indexed: 11/18/2022]
Abstract
BACKGROUND Empathy, consisting of cognitive empathy and affective empathy, is essential for creating relationships with others. Since the genetic polymorphism of oxytocin receptor (OXTR) and arginine-vasopressin V1B receptor (AVPR1B) relate to prosocial behavior and empathy, it would need to innovate strategies for treating human empathy by considering individual genetic variations. Physical activity is expected as a possible strategy; here, we investigated the influences of genetic polymorphisms in OXTR SNP rs53576 and AVPR1B SNP rs28373064, on the relationships of self-reported empathy with physical activity. METHODS The saliva is collected from a hundred Japanese college students for determining the individual polymorphism of OXTR SNP rs53576 (AA, AG, or GG genotype) and AVPR1B SNP rs28373064 (TT, TC, or CC genotype). In addition, the participants' self-reported cognitive and affective empathy, amounts of physical activity, and sitting time were evaluated with questionaries. RESULTS The participants with OXTR SNP rs53576 GG genotype showed a significant negative correlation between sitting time and cognitive empathy adjusted by age, gender, and sports experience. Further, there was a trend to correlate between physical activity amounts and cognitive empathy in the participants carrying the G variant in OXTR SNP rs53576 (AG or GG). As for AVPR1B SNP rs28373064, the persons with TT genotype exhibited a negative correlation trend between sitting time and cognitive empathy. CONCLUSIONS There are possible correlations between the self-reported cognitive empathy and physical activity amounts in the persons carrying the G variant of OXTR rs53576 or with the TT genotype for AVPR1B SNP rs28373064.

Abstract
The promotion of autonomic balance and social brain networks may explain the association of endurance exercise and social cognition. Specific nervous system functions and the regulating roles of oxytocin have evolved because of the necessity to negotiate increasingly complex social systems. We hypothesize that acute and long-term physical activity and exercise have the potential to benefit social cognitive abilities, such as emotion recognition and regulation, by operating on these functions.

Four weeks of light-intensity exercise enhances empathic behavior in mice: The possible involvement of BDNF. Brain Res 2022; 1787:147920. [PMID: 35452659 DOI: 10.1016/j.brainres.2022.147920] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2022] [Revised: 04/05/2022] [Accepted: 04/14/2022] [Indexed: 11/23/2022]
Abstract
Empathy is one of the essential functions of mammals for maintaining relationships with others. Physical activity contributes to enhancing empathic attitude and behavior; however, it is remained to cover the effective intensity of exercise on mammal empathy. Here, we tested the effects of light-intensity exercise, which has beneficial effects on expressing neurotrophic factors in the brain, on empathic behavior. Eight-week-old male C57BL/6 mice were subjected to forced wheel running at light-intensity (7.0 m/min, 30 min/day, 5 days/week) for 4 weeks. Then, all mice were subjected to helping behavior to evaluate their empathic behavior. The insular cortex was collected for analyzing the expressions of mRNA and miRNA. Four weeks of light-intensity exercise enhanced helping behavior. Exercised mice exhibited higher Bdnf gene expressions in the insular cortex than sedentary mice. In addition, there was a significant positive correlation between mRNA levels of Fndc5 and Bdnf in the insular cortex. Based on miRNA sequencing, 26 out of 51 miRNAs were significantly upregulated, and 25 out of 51 miRNAs were significantly downregulated in the insular cortex of mice with exercise. There were significant correlations between 11 out of 51 miRNAs and helping behavior; miR-486a-3p, which relates to FNDC5 expression, was contained. These results imply that miR-486a-3p/Fndc5/Bdnf pathway in the insular cortex would be a possible target for treating empathy.

Abstract
Although motor coordination and imitation are important factors affecting motor skill learning, few studies have examined the relationship between them in healthy adults. In order to address this in the present study, we used fNIRS to analyze the relationship between motor coordination and imitation in college students. Our results showed that: (1) motor coordination in female students was positively correlated with the average time taken to perform an imitation; (2) the mean imitation time was negatively correlated with the activation level of the supplementary motor cortex, primary somatosensory cortex, and angular gyrus of the mirror neuron system; (3) motor coordination in female students moderated mirror neuron system (MNS) activation and imitation. For women with low rather than high motor coordination, higher MNS activation was associated with a stronger imitation ability. These results demonstrate that motor coordination in female students is closely related to action imitation, and that it moderates the activation of the MNS, as measured via fNIRS.

Abstract
FNIRS pre-processing and processing methodologies are very important-how a researcher chooses to process their data can change the outcome of an experiment. The purpose of this review is to provide a guide on fNIRS pre-processing and processing techniques pertinent to the field of human motor control research. One hundred and twenty-three articles were selected from the motor control field and were examined on the basis of their fNIRS pre-processing and processing methodologies. Information was gathered about the most frequently used techniques in the field, which included frequency cutoff filters, wavelet filters, smoothing filters, and the general linear model (GLM). We discuss the methodologies of and considerations for these frequently used techniques, as well as those for some alternative techniques. Additionally, general considerations for processing are discussed.
