  • (13) As has now been observed in studies of serotonergic immunohistochemistry and in our own findings on VIP, histamine terminals were observed to lie in close contact with somata and axon hillocks, all of which suggest that axo-somatic connections in molluscs may be more prevalent than previously considered.
  • (14) Iontophoretic application of TTX inside the axon cap, a distinctive neuropil surrounding the initial segment and the axon hillock and circumscribed by a glial border, and at various positions along the lateral dendrite confirmed the Na+-dependency of the action potentials recorded in normal and axotomized cells and further demonstrated that the soma generates the additional spike component in the latter.
  • (15) At later post-treatment intervals (15 and 21 days), there were also alterations in the pericellular basket at the Purkinje cell axon hillock, which was poorly developed in or absent from the majority of cells.
  • (16) The P terminal occasionally surrounds an axon hillock, making symmetric synaptic contacts.
  • (17) A simple method is presented for selective cell culture of human mesangial cells using explantation of mesangial cell hillocks.
  • (18) The other allegation – that Alam and Park View's governing trust has taken over nearby schools – is also dismissed by Alam, who says that it was the DfE that asked Park View to take over two struggling schools: Golden Hillock secondary and Nansen primary, which is right next door.
  • (19) A few synaptic boutons were found on the surface of the axon hillock.
  • (20) The results that the cell membrane of axon hillock and proximal stem regions of many sensory large and small neurons may have numerous sodium channels and could affect signal propagation.
