[Adaptation of the central nervous system to optical correction].
Wearing spectacles imply an adjustment of the visual perception and eye movements. The visual cortex accounts for this plasticity, including at the adulthood, especially by the shift or the sprading of the receptor fields and the adjustment of the sensitivity of the primary visual cortex cells to spatial orientation and movement. The cerebellum modulates the vestibulo-ocular reflex gain. The adjustment latencies range from a few minutes to several days according to the disturbancy severity, the drug interferences and the age and medical history of the subject. Neurotrophins seem to be essential for this adjustment and might become an efficient tool to extend the plasticity period.
