thus , [ 3h ] prazosin and [ 3h ] wb4101 binding sites seen in forebrain regions such as lamina v of the cortex , thalamic nuclei and dorsal raphe probably represent alpha 1-adrenergic receptors and confirm electrophysiological and biochemical studies which demonstrate that adrenergic transmission in these regions can be mediated through an alpha 1-receptor .
