Sounds in everyday life seldom appear in isolation. Both humans and machines are constantly flooded with a cacophony of sounds that need to be sorted through and scoured for relevant information-a phenomenon referred to as the 'cocktail party problem'. A key component in parsing acoustic scenes is the role of attention, which mediates perception and behaviour by focusing both sensory and cognit...

Auditory spatial attention serves important functions in auditory source separation and selection. Although auditory spatial attention mechanisms have been generally investigated, the neural substrates encoding spatial information acted on by attention have not been identified in the human neocortex. We performed functional magnetic resonance imaging experiments to identify cortical regions tha...

Auditory attention has been examined extensively over the years, primarily by means of event-related brain potentials (ERPs). Sustained attention to specific targets embedded in a series of non-targets (e.g. the ‘oddball’ paradigm) causes an increase in the amplitudes of various components of the auditory ERP after about 80 ms and results in the appearance of new waveforms, such as the N2B and ...

Humans have the ability to pay attention one of sound sources in a multispeaker acoustic environment. Auditory detection (AAD) seeks detect attended speaker from one’s brain signals that will enable many innovative human–machine systems. However, effective representation learning electroencephalography (EEG) remains challenge. In this article, we propose neural mechanism dynamically assigns dif...
