- Literal Fig 8: "At presynaptic level, immunoparticles for Kv1.4 were observed in boutons of pyramidal cell axons (b) extrasynaptically (double arrows) and in presynaptic membrane specialization (double arrowheads) of synapses on spines (s)"
- Presynaptic localization is shown for neocortex (Fig 8I) and hippocampus (Fig.8J) [see double arrowheads]
- integral component in the annotation is derived from TM-domains in the annotated protein.
