NPY-immunoreactive profiles in the La at the ultrastructural level. NPY-immunoreactivity is localized in cell bodies frequently displaying indented nuclei (arrow in a), in dendrites (b) synaptically contacted by unlabeled terminals (inset represents magnification of boxed area in b; arrow points at synaptic cleft) and in axon terminals forming symmetric synapses (c arrows point at postsynaptic area in a small unlabeled dendrite). M mitochondrion, uD unlabeled dendrite, uT unlabeled terminal. Scale bar in a is 5,000 nm, in b and c 500 nm
