Abstract

The clarification of the biological basis of emotions in humans is an important neuroscientific issue with potential implications for the diagnosis and treatment of various mental disorders. Recent advances in neuroimaging studies demonstrate the existence of an organization of neural structures consistently related to the invocation and maintenance of emotional states. Concurrently, the development of neurofeedback technology introduces an innovative field for treatments of different types of diseases that affect the brain and may be a non-invasive and non-pharmacological alternative for affective disorders, for example. Thus, this study has the main objective to investigate the decoding capability of emotional states and the prefrontal cortex neuromodulation through a voluntary evocation of emotions. To this end, the subjects held emotional evocation and neurofeedback sessions based on spectroscopy near infrared (the acronym "NIRS").Additionally to the ability to differentiate the emotional patterns by the classifiers and the performance of the subjects in neurofeedback task, we will investigate spatial characteristics related to the patterns of interest. It enables better understanding of the neural substrates of emotional processes and possible improvements in neurofeedback systems.
