Neurofeedback (NFB) enables the voluntary regulation of brain activity, with promising applications to enhance and recover emotion cognitive processes, their underlying neurobiology. It remains unclear whether NFB can be used aid sustain complex emotions, ecological validity implications. We provide a technical proof concept novel real-time functional magnetic resonance imaging (rtfMRI) procedure. Using rtfMRI-NFB, we enabled participants voluntarily own neural activity while they...
In Ridley Scott's film "Blade Runner", empathy-detection devices are employed to measure affiliative emotions. Despite recent neurocomputational advances, it is unknown whether brain signatures of emotions, such as tenderness/affection, can be decoded and voluntarily modulated. Here, we multivariate voxel pattern analysis real-time fMRI address this question. We found that participants were able use visual feedback based on patterns a neurofeedback signal increase activation characteristic...
Amputation in adults is associated with an extensive remapping of cortical topography primary and secondary sensorimotor areas. Here, we used tactile residual limb stimulation 3T functional magnetic resonance imaging humans to investigate connectivity changes the network patients long-term lower traumatic amputations phantom sensation, but without pain. We found a pronounced reduction inter-hemispheric between homologous regions amputees, including (S1) (S2) somatosensory areas, (M1) (M2)...
In this methods article, we present a new implementation of recently reported FSL-integrated neurofeedback tool, the standalone version "Functional Real-time Interactive Endogenous Modulation and Decoding" (FRIEND). We will refer to as FRIEND Engine Framework. The framework comprises client-server cross-platform solution for real time fMRI fMRI/EEG studies, enabling flexible customization or integration graphical interfaces, devices data processing. This allows fast setup novel plug-ins...
Humans are intrinsically motivated to bond with others. The ability experience affiliative emotions (such as affection/tenderness, sexual attraction, and admiration/awe) may incentivize promote these bonds. Here, we interrogate the role of critical reward circuitry, especially Nucleus Accumbens (NAcc) septo-hypothalamic region, in anticipation response rewards using a novel incentive delay task. During Functional Magnetic Resonance Imaging (FMRI), participants (n = 23 healthy humans; 14...
Understanding the neural, metabolic, and psychological mechanisms underlying human altruism decision-making is a complex important topic both for science society. Here, we investigated whether transcranial Direct Current Stimulation (tDCS) applied to two prefrontal cortex regions, ventromedial (vmPFC, anode) right dorsolateral (DLPFC, cathode) can induce changes in self-reported emotions modulate local metabolite concentrations. We employed vivo quantitative MR Spectroscopy healthy adult...
During the last decades, neurofeedback training for emotional self-regulation has received significant attention from scientific and clinical communities. Most studies have investigated emotions using functional magnetic resonance imaging (fMRI), including real-time application in training. However, electroencephalogram (EEG) is a more suitable tool therapeutic application. Our study aims at establishing method to classify discrete complex (e.g., tenderness anguish) elicited through...
Abstract During the last decades, neurofeedback training for emotional self-regulation has received significant attention from both scientific and clinical communities. However, most studies have focused on broader states such as “negative vs. positive”, primarily due to our poor understanding of functional anatomy more complex emotions at electrophysiological level. Our proof-of-concept study aims investigating feasibility classifying two that been implicated in mental health, namely...
In this paper, we present the specification of a type genetic algorithm that was used for detection segments in ECG signal waves. The tested and evaluated its efficiency front samples obtained from MIT-BIH Arrhythmia Database results are also presented here. based on abstract data types implemented MatLab. showed detector can be systems detecting arrhythmias may become tool to improve medical care treatment is provided patients with cardiovascular problems.
