Abstract

The relations between the emotions and the brain's functioning have been the subject of scientific investigation over the past decade. This report continues this investigation in a single case study that required the subject to evoke different emotional states (happiness, love, depression) and rate the emotional states on an intensity scale while brain activity was monitored by quantitative electroencephalography (QEEG). The variations in brain activation patterns in these evoked emotional states indicated a predominant QEEQ activation of the beta2 (32–64 Hz) frequency range for all emotional states, with specificity of left hemisphere and temporal lobe activation for happiness and right hemisphere for depression. The response pattern also indicated a greater activation of central and posterior locations for the emotional states.
