-monocular deprivation produces structural and functional changes in the visual cortex and thalamus.

-Cortical neurons only respond to input from the nondeprived eye.

-During early development, active synapses in the visual cortex dominate over inactive synapses, thus, when one eye is deprived, synapses from that eye are retracted and the synapses from the nondeprived eye are maintained.

-Sensitive period for cats is the first four months of life and for rhesus monkeys the sensitive period six months.

-Ocular Dominance Histograms show the response of cells in the visual cortex under different conditions
