The drug discrimination assay for LSD in rats involves both 5-HT1A and 5-HT2A mediated components, and while lysergic acid 2-butyl amide is more potent than LSD as a 5-HT1A agonist, it is slightly less potent as a 5-HT2A agonist, and so would probably be slightly less potent than LSD as a hallucinogen in humans. The main use for this drug has been in studies of the binding site at the 5-HT2A receptor through which LSD exerts most of its pharmacological effects, with the stereoselective activity of these unsymmetric monoalkyl lysergamides foreshadowing the subsequent development of compounds such as lysergic acid 2,4-dimethylazetidide (LSZ). StarGeezer  StarGeezer is an album by folk artist "Spider" John Koerner, released in 1996. Some of the songs are re-recordings of titles previously released by Koerner on albums that are no longer in print. In his Allmusic review, critic Thom Owens wrote, "There aren't any standout songs, but the entire album has a relaxed, welcoming vibe that makes it quite a pleasant listen." Tom Sinclair of "Entertainment Weekly" called "StarGeezer" "a rootsy album of traditional folk and wry originals," and added that Koerner "shows that four decades of obscurity haven't diminished his talent for making engaging music out of wholly familiar elements." All songs traditional unless otherwise noted. Production notes     Washington County Railroad  Washington County Railroad or Railway may refer to:     S. K. Shivakumar  S. K.
