“…Due to its positive effects in clinical practice, there has been growing interest in research to verify whether neurofeedback training (NFT) could also positively influence the cognitive abilities of healthy individuals [ 20 ]. Some studies seem to support this hypothesis [ 21 ]. According to Klimesch (1999), the individual upper alpha band is of great importance for cognitive performance [ 22 ].…”

(1) Background: Neurofeedback training (NFT) has emerged as a promising approach for enhancing cognitive functions and reducing anxiety, yet its specific impact on university student populations requires further investigation. This study aims to examine the effects of NFT on working memory improvement and anxiety reduction within this demographic. (2) Methods: A total of forty healthy university student volunteers were randomized into two groups: an experimental group that received NFT and a control group. The NFT protocol was administered using a 14-channel Emotiv Epoc X headset (EMOTIV, Inc., San Francisco, CA 94102, USA) and BrainViz software version Brain Visualizer 1.1 (EMOTIV, Inc., San Francisco, CA 94102, USA), focusing on the alpha frequency band to target improvements in working memory and reductions in anxiety. Assessment tools, including the Corsi Block and Memory Span tests for working memory and the State-Trait Anxiety Inventory-2 (STAI-2) for anxiety, were applied pre- and post-intervention. (3) Results: The findings indicated an increase in alpha wave amplitude in the experimental group from the second day of NFT, with statistically significant differences observed on days 2 (p < 0.05) and 8 (p < 0.01). Contrary to expectations based on the previous literature, the study did not observe a concurrent positive impact on working memory. Nonetheless, a significant reduction in state anxiety levels was recorded in the experimental group (p < 0.001), corroborating NFT’s potential for anxiety management. (4) Conclusions: While these results suggest some potential of the technique in enhancing neural efficiency, the variability across different days highlights the need for further investigation to fully ascertain its effectiveness. The study confirms the beneficial impact of NFT on reducing state anxiety among university students, underscoring its value in psychological and cognitive performance enhancement. Despite the lack of observed improvements in working memory, these results highlight the need for continued exploration of NFT applications across different populations and settings, emphasizing its potential utility in educational and therapeutic contexts.

“…It is regulated by frontal and posterior brain regions and is mainly associated with the beta power of the electroencephalogram (EEG) [3,4]. Noninvasive and nonpharmacological modalities such as repetitive transcranial magnetic stimulation, transcranial direct current stimulation, binaural beats, and neurofeedback (NF) are becoming popular in attention or whole cognitive function management [5][6][7][8]. NF involves real-time voluntary modulation of specific EEG features, primarily beta power from frontal or central regions, to enhance and improve attentional processes [9].…”

Attention is a cognitive process that involves focusing mental resources on specific stimuli and plays a fundamental role in perception, learning, memory, and decision-making. Neurofeedback (NF) is a useful technique for improving attention, providing real-time feedback on brain activity in the form of visual or auditory cues, and allowing users to learn to self-regulate their cognitive processes. This study compares the effectiveness of different cues in NF training for attention enhancement through a multimodal approach. We conducted neurological (Quantitative Electroencephalography), neuropsychological (Mindfulness Attention Awareness Scale-15), and behavioral (Stroop test) assessments before and after NF training on 36 healthy participants, divided into audiovisual (G1) and visual (G2) groups. Twelve NF training sessions were conducted on alternate days, each consisting of five subsessions, with pre- and post-NF baseline electroencephalographic evaluations using power spectral density. The pre-NF baseline was used for thresholding the NF session using the beta frequency band power. Two-way analysis of variance revealed a significant long-term effect of group (G1/G2) and state (before/after NF) on the behavioral and neuropsychological assessments, with G1 showing significantly higher Mindfulness Attention Awareness Scale-15 scores, higher Stroop scores, and lower Stroop reaction times for interaction effects. Moreover, unpaired t-tests to compare voxel-wise standardized low-resolution brain electromagnetic tomography images revealed higher activity of G1 in Brodmann area 40 due to NF training. Neurological assessments show that G1 had better improvement in immediate, short-, and long-term attention. The findings of this study offer a guide for the development of NF training protocols aimed at enhancing attention effectively.

Introdução: O transtorno de estresse pós-traumático (TEPT) é um problema de saúde mental proeminente em militares veteranos e, também, na população em geral. Podendo durar desde apenas alguns meses a muitos anos, causa diversas incapacidades aos indivíduos que sofrem com o transtorno. Existem opções não medicamentosas que podem, não apenas contribuir, como até mesmo serem necessárias para a recuperação integral de pacientes com TEPT. Objetivo: Examinar as interações entre aspectos fisiológicos-psicofisiológicos e eletrofisiológicos (padrões corticais) com exercício físico, buscando possíveis alternativas não-medicamentosas para o tratamento de pacientes com transtorno de estresse pós-traumático (TEPT). Resultados e Discussão: A disfunção do hipocampo e causa o TEPT e problemas no funcionamento cerebral (ansiedade, depressão e comprometimento cognitivo), além de prejuízos na função mitocôndria e na neuroplasticidade. O exercício físico e a neuromodulação autorregulatória podem contribuir, e até serem indispensáveis, para a recuperação desses pacientes. Conclusão: Exercícios físicos, por meio da melhora induzida do nível do fator neurotrófico derivado do cérebro, do aprimoramento da função mitocondrial e da indução à neuroplasticidade e a taxa de apoptose no hipocampo contribui para a recuperação de pacientes com TEPT. Além disso, indica-se a neuromodulação autorregulatória.
