The presence of secondary sensory cells in the Octopus gravity receptor system has been demonstrated. In serial thin sections of the receptor cells (hair cells) no axons were found leaving the cells. Instead, synapses were observed with synaptic vesicles lying inside the receptor cells. Both data clearly indicate that the receptor hair cells represent(More)

In spite of considerable diversity in their outer structures, the organs manifest many similarities in their internal structure (pore system with pores of about 50-100 A diameter, a single sensory cell with two branching ciliary outer segments, reduction of the outer receptor lymph(More)
