This paper proposes a version of the brain mechanism for emergence and formation of perceptual and mental images. The initial event of perceptual image emergence is the result of interaction on thalamic relay neurons between chaotic sensory impulse flow and also impulse flow organized in trains and coming from reticular structures. The subsequent step is the formation of a metastable dynamic association of excited allocortex columns. The role played by the functional association of allocortex columns and the intrafusal muscular reception in the activation of distributed brain systems and in the formation of a perceptual image is considered. This image is seen as a meta-stable state of synergistic processes in neuromuscular structures. The rationale for the imperceivableness of a perceptual image is given. It is assumed that a mental image is based on the perceived effects of Newtonian forces caused by muscle contractions. Properties of perceptual and mental images, their difference and conjugacy, and also the role of a mental image in interaction with conscious images are discussed.
