Neurodevelopment

When different stimuli are presented it gives the brain the capability to build new

connections and to grow. When the brain is deprived of stimuli those connections cannot be

made. Plasticity of the brain means the brains neurons can continuously grow new connections.

Visual stimulation can enhance these growths and connections resulting in the thickening of the

cortex and more synapses per neuron. Plasticity is at its peak during the developmental stages in

a person's life, after adulthood it slowly decreases. Critical sensitive periods are early stages of

development; children develop double the amount of neurons that adults do. That is why it is

easier for children to learn a second language rather than learning it in adulthood. Without visual

stimulation of any stimuli for that matter, it doesn't allow for full cognitive development, and

also with deprived visual stimulation that can result in undeveloped parts of the eye. Sensory

cortex and auditory cortex are important when developing. The potential is there and once the

stimuli are presented the full capability can be shown. In a study it was shown that an eye that

was deprived of light for a few days suffered weakness as a
