Multisensory facilitation of behavior in monkeys: effects of stimulus intensity

Cappe, Céline ; Murray, Micah M. ; Barone, Pascal ; Rouiller, Eric M.

In: Journal of Cognitive Neuroscience, 2010, vol. 22, no. 12, p. 2850-2863

Multisensory stimuli can improve performance, facilitating RTs on sensorimotor tasks. This benefit is referred to as the redundant signals effect (RSE) and can exceed predictions on the basis of probability summation, indicative of integrative processes. Although an RSE exceeding probability summation has been repeatedly observed in humans and nonprimate animals, there are scant and inconsistent...

The thalamocortical projection systems in Primate : an anatomical support for multisensory and sensorimotor interplay

Cappe, Céline ; Morel, Anne ; Barone, Pascal ; Rouiller, Eric M.

In: Cerebral Cortex, 2009, vol. 19, no. 9, p. 2025-2037

Multisensory and sensorimotor integrations are usually considered to occur in superior colliculus and cerebral cortex, but few studies proposed the thalamus as being involved in these integrative processes. We investigated whether the organization of the thalamocortical (TC) systems for different modalities partly overlap, representing an anatomical support for multisensory and sensorimotor...
