Ontogenesis of beta-adrenergic binding sites in kitten visual cortex and the effects of visual deprivation

We have determined maximum binding capacities for beta-adrenergic binding sites in developing cat visual cortex. These increase quickly from birth to 4 weeks, after which time a slower increase reaches maximal levels at 12 weeks. Dark-rearing and monocular eyelid suture have no influence on this developmental profile.
