Introduction. Heart rate variability (HRV) is considered a marker of autonomic nervous system (ANS) function and a biomarker of interest in evaluating nervous system function following traumatic brain injury. This study validates prior research with larger sample sizes and proposes a model for establishing baseline HRV reactivity in healthy participants. Methods. Sixty-two healthy collegiate athletes were recruited for this study. Following informed consent, they were evaluated supine using the Elite HRV CorSense monitor and platform to record low frequency/high frequency (LF/HF) ratio and root means square of successive differences (RMSSD) over 5 min. A bag of ice was placed on their face, then RMSSD and LF/HF ratio were collected over three successive 1-min intervals. Results. RMSSD was elevated at 1 and 2 min (+47.4 ms, p < .0001; +16.5 ms, p = .014) following face cooling and fell to baseline at 3 min (+4.6 ms, p = .52). LF/HF ratio decreased following face cooling at 2 and 3 min (change from rest %: 2 min, −33%, p = .007; 3 min, −50%, p = < .0001). Conclusion. The Elite HRV platform can detect an elevation in RMSSD in the first minute following face cooling with a return to baseline in the second and third minutes. It can also detect a consistent decrease in LF/HF following face cooling.

Alpha band oscillations are characterized phenomenologically by a state of relaxed, unfocused attention and are implicated in enhanced learning and memory performance. Alpha power may reflect cortical inhibition in task-irrelevant brain regions, thus leaving more neural resources available to task-relevant regions and processes. In this paper we propose that a short priming session with a posterior alpha upregulation protocol may accelerate subsequent neurofeedback learning with the client’s main training protocols. Neurofeedback relies to a large extent on implicit learning processes mediated by the basal ganglia and frontal cortical regions. Alpha uptraining posteriorly may inhibit task-irrelevant cortical regions dedicated mostly to explicit processing and externally oriented attention, thereby clearing the way for cortical and subcortical regions directly involved in neurofeedback learning to process the feedback more efficiently. It may thus serve to accelerate the learning process and efficacy of neurofeedback training. Various considerations and possible side effects are discussed.

Introduction: Traumatic brain injury (TBI) is associated with physical, cognitive, emotional, and behavioral disturbances. The cognitive deficits are common after TBI, and a holistic approach to neuropsychological rehabilitation is recommended in these patients. EEG neurofeedback training (EEG-NFT) is a state-of-the-art technique for neuropsychological rehabilitation. There is a paucity of studies exploring the use of EEG-NFT integrated with holistic neuropsychological rehabilitation. Method: Single case design was adopted for the present study. A 25-year-old single male, diagnosed with severe TBI, presented with physical, cognitive, and emotional-behavioral disturbances after 17 months of injury. A comprehensive neuropsychological assessment was carried out. The neuropsychological rehabilitation using EEG-NFT along with psychosocial interventions with the patient and the parents was carried out for 9 months. Results: The patient showed significant improvement in cognitive deficits such as attention, executive functions, and visuospatial ability. Emotional-behavioral problems such as irritability, sadness, and overall dysfunction also improved significantly. Conclusion: The present case study highlights that integrating EEG-NFT along with holistic neuropsychological rehabilitation helps to improve cognitive, emotional, and behavioral disturbances after TBI.

Gambling disorder (GD) is an addictive behavioral disorder that alters the frontostriatal neural circuitry and prefrontal control of reward-associated brain areas. An intrusion between prefrontal cortex and the mesolimbic reward pathway has been proposed as the major mechanism behind the pathogenesis of GD. Repetitive transcranial magnetic stimulation (rTMS) is a noninvasive treatment that utilizes magnetic fields to stimulate nerve cells linked to mood and behavioral control; this stimulation is usually applied either on the left or right side of the dorsolateral prefrontal cortex of the brain. rTMS selectively modulates the activities of brain circuits and possess the ability to overturn the alterations in the neurocircuitry of the brain linked to the pathophysiology of GD. rTMS adjusts impulsivity, cognitive/attentional control, cognitive plasticity, and decision-making, which are crucial in decreasing gambling craving and relapse. However, innovative clinical investigations are needed to analyze and establish the impact of rTMS on gambling craving and cessation, using a larger sample size.

The aim was to analyze the relationship between the quality of diet and academic performance in rural primary school students, a cross-sectional study made up of 181 rural schoolchildren (8.75 ± 1.79 years) from the island of Fuerteventura. Academic performance was calculated through the average grade in the subjects described in Royal Decree 126/2014, February 28th. The quality of the Mediterranean diet was assessed through the KIDMED questionnaire. The one-way analysis of variance (ANOVA) test did not reflect statistically significant differences in academic performance as a function of the quality of the Mediterranean diet, neither in men nor in women ( p > .005). The multinomial logistic regression test after adjusting for sex and age, reflected that schoolchildren with a higher quality of diet were more likely to have passed the areas of Social Sciences and Natural Sciences when compared to their failed peers ( p < .05). Thus, a higher quality of the diet in rural primary schoolchildren seems to be associated with passing the areas of Social Sciences and Natural Sciences. Health promotion professionals in the school environment must consider the positive role that diet can play in academic performance and start programs to promote healthy eating among schoolchildren.

Background : Mental illnesses are increasing worldwide with the internalizing disorders (IDs; e.g., anxiety disorders, depressive disorders) being the most prevalent. Current first-line therapies (e.g., pharmacotherapy) offer high failure rates and substantial side effects. Electroencephalographic neurofeedback (EEG-NFB) has been shown to be an effective and safe treatment for these conditions; however, there remains much doubt regarding the existence of specificity (i.e., clinical effects specific to the modulation of the EEG variables of interest). This is a protocol for a quantitative review that will attempt to determine if there is evidence for EEG-NFB specificity in the treatment of IDs. Methods : We will consider all published and unpublished randomized, double-blind (i.e., trainees and raters), sham/placebo-controlled (i.e., feedback contingent on a random signal, the activity from a different person’s brain, or an unrelated signal from the trainee’s own brain) trials involving humans with at least one ID diagnosis without exclusion by language, locality, ethnicity, age, or sex. Effect sizes will be calculated for individual studies and combined in a meta-analysis. Discussion : This protocol outlines the research methodology for a quantitative review undertaken to assess for evidence of EEG-NFB specificity in the treatment of

Complex developmental trauma (CDT) is characterized by prolonged exposure to traumatic events in early life, resulting in the breakdown of neurobiological integration which impacts mental and physical health. The benefits of practicing short-form improvisation (improv), however, parallel the treatment needs of this population. To observe the neurobiological effect of improv, we used eyes-open quantitative electroencephalography (qEEG) to record the brains of 32 adolescents before and after participation in a 20-min intervention (One Rule Improv) consisting of short-form improv games. A paired t -test was used to evaluate coherence, phase, absolute amplitude, and low-resolution electromagnetic tomography (LORETA). Results indicated increases in coherence in delta, theta, alpha, and beta ( p < .05). Phase lag showed a statistical decrease ( p < .05) in delta, alpha, and beta. Absolute power showed significant increases in alpha frontally Fp1 ( p = .004), decreases in delta ( p = .030) at T4. LORETA analysis indicated significant changes in sensorimotor rhythm (SMR) at Brodmann area (BA) 6, t (27) = 6.1, p < .05. Significant delta decreased at BA 6, BA 10, t (27) = 4.96, p < .05; and BA 24, t (27) = 3.90. Significant delta decreased at BA 4, BA 3, and BA 40, t (27) = 4.35, p < .05. Results indicate preliminary evidence supporting improv as an intervention capable of affecting functional connectivity changes in adolescents with CDT. For developmental trauma, these results may indicate improved capacity to make meaningful connections with others and create opportunities for neuroplastic
