在幼猫的视觉皮层中，单眼眼睑短暂缝合后眼优势移位的程度低于局部灌注中等浓度β-肾上腺素能受体阻滞剂的半球的预期。目前的结果不是由于类似于双眼剥夺的作用，因为β-肾上腺素能受体阻滞剂的“局部麻醉作用”不太可能涉及目前的范例。因此，本研究结果与视皮层内的β-肾上腺素能受体对于视皮层可塑性的调节是必需的（至少部分是必需的）这一观点一致。
In the visual cortex of young kittens, the extent of ocular dominance shift following brief monocular lid suture was less than expected in the hemisphere which had been locally perfused with β-adrenergic receptor blockers at a moderate concentration. The present result was not due to the effect similar to binocular deprivation, since “local anesthetic effect” of β-adrenergic blockers was unlikely to be involved in the present paradigm. Thus, the present results are consistent with the idea that β-adrenergic receptors within the visual cortex are necessary, at least in part, for the regulation of visuocortical plasticity.
