Selective Attention Decoding
- Auditory selective attention: Focus on target speaker in background noise
- Cerebral cortex activity in delta (1-4 Hz) and theta (4-8 Hz) band tracks envelope of attended speech
- Envelope can be reconstructed based on single-trial electroencephalography (EEG)
Our EEG systems:
- High-desity scalp EEG
- cEEGrid
- Invasive EEG
Future application: Neuro-steered cochlear implants (CIs)
