Neurite branch development of an identified serotonergic neuron from embryonic Helisoma: evidence for autoregulation by serotonin.
Previous studies have shown that in select neurons, neurite outgrowth can be regulated by the same neurotransmitter that is synthesized and released by those neurons. However, it is not known whetherExpand

Interactions of gonadal steroids with brain dopamine and gonadotropin-releasing hormone in the control of gonadotropin-II secretion in the goldfish.
In goldfish it is known that intraperitoneal implantation with testosterone (T) or estradiol (E2) potentiates the serum gonadotropin-II (GtH-II) response to gonadotropin-releasing hormone (GnRH)Expand
