METODOLOGÍA PARA EL ESTUDIO DE SEÑALES SINÁPTICAS MEDIANTE UN SISTEMA DE EEG PORTÁTIL (METHODOLOGY FOR STUDYING SYNAPTIC SIGNALS USING A PORTABLE EEG SYSTEM)
Resumen
El EMOTIV EPOC+ es un sistema de electroencefalograma (EEG) portátil de alta resolución frecuentemente utilizado para sistemas BCI que es una interfaz de computadora con el cerebro. La interfaz cerebro-computadora (BCI) a través de la electroencefalografía (EEG) atrae la atención de la comunidad científica gracias a sus últimas mejoras en términos de rendimiento y aplicaciones. Mediante el software EmotivPRO se adquieren las señales EEG del EPOC + a través de conexión Bluetooth entre el auricular y la computadora. El análisis en frecuencia permite la detección y el estudio de trastornos psicológicos, el software EmotivPro permite obtener las frecuencias fundamentales derivadas del cálculo de la Transformada Rápida de Fourier. Esta información ha sido utilizada por diversos autores para el análisis de patologías psicológicas. El presente estudio se centra en el uso del Emotiv Epoc utilizando el software EmotivPro para obtener las señales alpha, beta, theta y gamma ya que estas son los marcadores que diferencian entre una persona sana y una persona con algún tipo de trastorno psicológico.
Palabras Clave: Electroencefalograma, Emotiv, trastorno psicológico.
Abstract
The EMOTIV EPOC + is a high resolution portable electroencephalogram (EEG) system frequently used for BCI systems that is a computer interface to the brain. The brain-computer interface (BCI) through electroencephalography (EEG) attracts the attention of the scientific community thanks to its latest improvements in terms of performance and applications. Through the EmotivPRO software, the EEG signals of the EPOC + are acquired through a Bluetooth connection between the headset and the computer. The frequency analysis allows the detection and study of psychological disorders, the EmotivPro software allows obtaining the fundamental frequencies derived from the calculation of the Fast Fourier Transform. This information has been used by various authors for the analysis of psychological pathologies. The present study focuses on the use of the Emotiv Epoc using the EmotivPro software to obtain the alpha, beta, theta and gamma signals since these are the markers that differentiate between a healthy person and a person with some type of psychological disorder.
Keywords: Electroencephalogram, Emotiv, psychological disorder.
