The role of high spatial frequencies in hemispheric processing of categorical and coordinate spatial relations.

abstract：:Neural responses in early sensory areas are influenced by top-down processing. In the visual system, early visual areas have been shown to actively participate in top-down processing based on their topographical properties. Although it has been suggested that the auditory cortex is involved in top-down control, functi...
