We live in a “multisensory” world Information can be processed on a modality- specific basis Information converges and is integrated in the brain Performance enhancement is larger for multisensory than unisensory stimuli
Color Discrimination Task (Multisensory) (Unisensory)
Multisensory Brain Regions Superior temporal sulcus –STS (BA 22) Inferior temporo-occipital –BA 19/37 Angular gyrus –BA 39/40 Cingulate gyrus –BA 32/9/10 Brodmann Areas
Superior Temporal Sulcus Calvert et al, Current Biology 2000, 10:649–657 Beauchamp et al. – Nature Neuroscience 2004, Atteveldt et al. Neuron , 271–282.
Inferior Temporo-occipital L. Cohen et al. NeuroImage 23 (2004) 1256–1270 Hashimoto et al, Neuron, Vol. 42, (2004) 311–322 Beauchamp et al, Neuron, Vol. 41, 809–823, March 4, 2004,
Angular and Cingulate Gyri Saito et al Cereb Cortex. 2005, 15: Nonlinguistic Linguistic Laurienti et al. (2003) de Zubicaray et al. (2002)
Unisensory Brain Regions Brodmann Areas Do the unisensory cortices interact? How does attention modulate unisensory activity? Are unisensory interactions altered in dyslexia?
Unisensory Brain Regions Cross-modal deactivations are modulated by selective attention Unpublished data removed AuditionVision Laurienti et al. (2002)
Phoneme Recognition Task Dyslexic readers do not deactivate visual cortex during an auditory processing task Unpublished data removed
Imaging Multisensory Processes Multiple multisensory cortical regions Factors that modulate behavior (coincidence, congruence, attention) also modulate fMRI Unisensory and multisensory regions are closely situated Cross-modal deactivations Altered multisensory processing in dyslexia
