Galanin and its binding sites in the brain of eels submitted to different osmolar conditions
A galanin (GAL)-like peptidergic system was investigated in the brain of Anguilla anguilla subjected to hyperosmolar and hypoosmolar conditions, by using antisera raised against porcine 1–29 GAL. A group of immunoreactive perikaria was identified in the periventricular hypothalamus, in the ventral t...
