Neural and hormonal consequences of neonatal 5,7-dihydroxytryptamine may not be associated with serotonin depletion.


The neurotoxin 5,7-dihydroxytryptamine (5,7-DHT) is often used in neonatal rats to induce specific, rapid, and permanent depletion of brain serotonin (5-HT). One assumed benefit of using this drug in neonates is that it is well-tolerated, with pups exhibiting few side effects normally attributed to 5-HT depletion. Here, we present evidence that 5,7-DHT… (More)
