Right superior posterior parietal lobe is essential in mental rotation and this activity is consistent with a variety of visuospatial and visuomotor transformations. Evidence suggest visual imagery is similar to visual perception of objects.

Bilateral superior parietal lobule lateral premotor area and supplementary motor area involved in mental rotation in all subjects. Also activated in visual perception. Evidence suggests same areas in visual imagery and visual perception.

Results from image scanning studies reflect metric properties of mental imagery. Mental imagery uses mechanisms that are used to encode and interpret objects during perception.

Laeng & Teodorescu (2001)
Eye movements during visual scanning and imagery of an irregular checkerboard or coloured pictures of fish. The order of scanning correlated to the order of perception. Eye scanpaths during visual imagery re-enact those of perception.

Borst & Kosslyn (2008)
Exp. 1 scanned over patterns of dots. Exp. 2 mental images created from information in LTM, pts scanned more slowly. Evidence suggests mental images and perceived stimuli are represented similarly and can be processed in the same way.

Kosslyn et al (1996)
PETs and fMRIs. Create visual images of letters from the alphabet. PET showed bloodflow to occipital visual cortex. The same region activated when perceiving the shape of actual visual stimuli. Evidences suggests same areas in brain used during v.i/p

Farah et al (1988)
ERPs. Reading task- Exp. 1 read concrete words. Exp. 2 read and imagine each word. Similar activity for 450ms. Evidence suggests similar brain activity during v.i/p.

Ganis, Thompson & Kosslyn (2004)
fMRIs. Pts visualised or saw faint drawings and asked to judge specific aspects. Results demonstrate same neural machinery for v.i/p. Evidence suggests brain same neural mechanisms used in v.i/p.
