autoradiography showed that the receptor subpopulation labelled with [ 125i ] 204-090 , which we named ss1 , was preferentially localized in layers v and vi , whereas the subpopulation having low affinity for somatostatin octapeptides ( named ss2 ) , measured with somatostatin-28 radioligand , was concentrated in the superficial cortical layers ( i-iv ) and particularly enriched in parts of lamina iv .
