Listening to numbers affects visual and haptic bisection in healthy individuals and neglect patients

► Numbers are represented in a spatial format, the mental number line (MNL). ► The MNL has been found to affect space representation. ► Here we show that listening to numbers affects visual and haptic line bisection. ► Critically, this effect was observed also in patients with left unilateral neglect. ► Neglect does not prevent a crossmodal interaction between numbers and space.
