Neuronal specificity is not the only “force” or effect governing the regrowth of axons (after e.g. an optic nerve crush).
Squint eye = eye that is not properly calibrated (i.e. it becomes “unused” by the brain, leading to for example lazy eye).
Binocular vision = stereo vision where oculi are close together (e.g. humans).
Ocular dominance columns → make sure that stereo vision field is properly mapped inside the (6?) layers of the visual cortex.
In new-borns, the ocular dominance columns are not yet present (i.e. underdevelopment), hence blurry vision. Over time, the visual system gets finetuned (i.e. formation of ocular dominance columns), leading to clear vision.
Axonal competition; inactive axons are eliminated dependent on the visual experience of the individual during the finetuning period (e.g. other eye “takes over function”).
Depth of field (i.e. focus on an object) is dependent on the angle at which the eyes focus on an object.
Experience during finetuning defines stereo vision. Lack of stereovision ⇒ lack of development of stereovision.
