The neural link between stimulus duration and spatial location in the human visual hierarchy.

ABSTRACT: Integrating spatial and temporal information is essential for our sensory experience. While psychophysical evidence suggests spatial dependencies in duration perception, few studies have directly tested the neural link between temporal and spatial processing. Using ultra-high-field functional MRI and neuronal-based modeling, we investigated how and where the processing and the representation of a visual stimulus duration is linked to that of its spatial location. Our results show a transition in duration coding: from monotonic and spatially-dependent in early visual cortex to unimodal and spatially-invariant in frontal cortex. Along the dorsal visual stream, particularly in the intraparietal sulcus (IPS), neuronal populations show common selective responses to both spatial and temporal inf
