First detection of neuropeptide Y (NPY)-like immunoreactivity in the lateral line: presence and distribution in the neuromasts of the Antarctic notothenioid fish Trematomus bernacchii
The mechanosensory lateral line (LL) is involved in many fish and amphibian behaviors, however little is known about the molecules involved in the signal transmission. Neuropeptide Y (NPY) has a num- ber of functions in vertebrate physiology and also plays important roles in different sensory system...
