Investigating the role of task relevance during rhythmic sampling of spatial locations

open access: yesScientific Reports, 2023
Recently it has been discovered that visuospatial attention operates rhythmically, rather than being stably employed over time. A low-frequency 7–8 Hz rhythmic mechanism coordinates periodic windows to sample relevant locations and to shift towards other,

Modality-specific Affective Responses and their Implications for Affective BCI [PDF]

open access: yes, 2011
Reliable applications of multimodal affective brain-computer interfaces (aBCI) require a detailed understanding of the processes involved in emotions. To explore the modality-specific nature of affective responses, we studied neurophysiological responses
