The effect of sound removal (present study) and object removal (Watanabe et al. 2008) on cortical activation in response to the sound‐object stimuli

	No‐sound (present study)	No‐object [Watanabe et al., 2008]
Response patterns Reduction		Regions
Deactivation	STG (early auditory), MTGa*	·
No activation	SFG	MOG (LO), SFG
Activation	MOG (early visual), MTGp, MTGa*, IPL	MTGp, IPL, IFG
No difference
Activation	MOG (LO), IFG	MOG (early visual), STG (early auditory), MTGa

Notes: The following response patterns were observed; deactivation: significant activation in the multisensory condition and significant deactivation in the condition wherein either the object or sound stimulus was removed; no activation: significant activation in the multisensory condition and no significant activation upon removal of either of the stimuli, with significant differences being observed between the 2 conditions; reduced activation: significant activation in the multisensory condition and the condition in which one of the stimuli had been removed, followed by significant reduction in activation upon removal of either of the stimuli as compared to activation in the multisensory condition and the condition in which either of the stuimuli had been removed, with no significant difference being observed between the 2 conditions. The asterisks (*) indicate that the MTGa region showed activation in the early time window and deactivation in the later time window in the no‐sound condition.
