They are indeed, but they are not neurons. As I seem to
recall, these receptors are composed modified connective-tissue cells,
and are *innervated* by sensory neurons with distant cell bodies.
The generator potential occurs in the dendrite(s) of the sensory
Similarly, gustatory cells in taste buds are made of modified
epithelial cells (I think), and again are innervated by cranial
sensory neurons in somewhat distant ganglia.
