Changes in EEG amplitude (Alpha and Beta waves) with Thermal environment

When executing a task, brain activity can be observed through electric waves recorded in different frequency bands. The main ones are the Alpha, Beta, Theta and Delta waves. According to some authors, Alpha and Beta waves are related with cognitive capacity and, their presence and evolution, with an...

Los principales son las ondas Alfa, Beta, Theta y Delta. Según algunos autores, las ondas Beta y Alfa están relacionados con la capacidad cognitiva y, su presencia y evolución, la aparición y evolución, con el estado de alerta de un individuo. En este estudio, la intención fue evaluar cómo actividad cerebral está directamente influenciada por la temperatura y humedad mientras realiza una tarea. Por lo tanto, se llevaron a cabo un conjunto de pruebas de laboratorio para simular trabajo sedentario en dos diferentes ambientes térmicos: 18 ºC - 40% RH (en frío) y 35 ºC - 80% RH (caliente). En el ambiente térmico caliente, la oscilación de amplitud de las ondas alfa sugiere una alternancia entre periodos de cansancio con los períodos en que aumenta la concentración. Con respecto a las ondas Beta en el ambiente térmico frío, la mayoría de la actividad Beta es típicamente mayor que el verificado en el ambiente térmico caliente.application/pdfspaUniversidad Nacional de Colombia (Sede Medellín).
