The results support the hypothesis that visual imagery is a function of the visual association cortex.
In other words, it is possible that similar information from different sensory modalities might be processed within the same brain region and that the visual association cortex might not only be involved in visual processing.

The SMA area presents efferent connectivity to posterior sensory association cortex and to primary motor areas (Kunzle, 1978).
Areas that receive projections from primary cortex are called unimodal sensory association cortex. Unimodal cortex projects to polymodal or heteromodal association cortex, so called because it processes more than one type of sensory input.
The lower bank of the sylvian fissure contains the primary auditory cortex on Heschl's gyms and auditory association cortex on the planum (Figure 4).
Afferent input into these nuclei is from the cerebral cortex, information being received from the primary motor cortex (Brodmann's area 4), primary sensory cortex (Brodmann's area 3, 1, 2), association cortex (Brodmann's area 5), premotor cortex (Brodmann's area 6), and supplementary cortex (Brodmann's area 6).
After completing this training, the animals displayed coinciding bursts of gamma-wave activity in areas of the visual cortex and the association cortex as they eyed the grating and waited for it to rotate.
