We attempt to decode emotional valence from electroencephalographic rhythmic activity in a naturalistic setting. We employ a data-driven method developed in a previous study, Spectral Linear Discriminant Analysis, to discover the relationships between the classification task and independent neuronal sources, optimally utilizing multiple frequency bands. A detailed investigation of the classifier provides insight into the neuronal sources related with emotional valence, and the individual…

Anger and frontal brain activity: EEG asymmetry consistent with approach motivation despite negative affective valence.
- Psychology, BiologyJournal of personality and social psychology

The hypothesis that dispositional anger, an approach-related motivational tendency with negative valence, would be associated with greater left- than right-anterior activity was tested, suggesting that the anterior asymmetry varies as a function of motivational direction rather than affective valence.

Recent findings indicate that network oscillations bias input selection, temporally link neurons into assemblies, and facilitate synaptic plasticity, mechanisms that cooperatively support temporal representation and long-term consolidation of information.
