In order to understand the interaction between different senses in the brain it is necessary to be able to use multisensory stimulation. We use multisensory stimulation, with the possibility of auditory, visual, somatosensory, as well as elecctrical stimulation via cochlear implants. We use matlab controlled stimuli and IO-cards with a special emphasis of temporal precise sensory stimulation (ViewPIXX, Psychtoolbox, NI cards, Stroboscope, CI, Speaker).
