the eye on the opposite side (the contralateral eye) sends information to layers 1, 4 and 6. This description applies to the LGN of many primates, but not all. The sequence of layers receiving information from the ipsilateral and contralateral (opposite side of the head) eyes is different in the tarsier. [10]
Dogs also have a greater divergence of the eye axis than humans, enabling them to rotate their pupils farther in any direction. The divergence of the eye axis of dogs ranges from 12–25°, depending on the breed. [36] Experimentation has found that dogs can distinguish between complex visual images such as those of a cube or a prism.
The depth of the olfactory fossa is determined by the height of the lateral lamella of the cribriform plate. Keros in 1962, classified the depth into three categories. [3] type 1: has a depth of 1–3 mm (26.3% of population) type 2: has a depth of 4–7 mm (73.3% of population) type 3: has a depth of 8–16 mm (0.5% of population)
Its peripheral part is formed by the eyes, the intermediate (by the transmission of nerve impulses) - the optic nerves, and the central - the visual centers in the cerebral cortex. The recognition of visual stimuli in mammals is the result of the joint work of the eyes and the brain.

This is a result of the slippery lamellae sliding past each other when the corpuscle is structurally deformed by external pressure so that effects of sustained pressure are soon dissipated by the lamellae, abolishing deformation of the central axon terminal itself. [8] The capsule thus acts as a physiological high-pass filter. [3]
