Abstract
This chapter summarizes the results of intracellular electrophysio-logical recordings obtained from lobster olfactory receptor cells in response to stimulation with complex odor mixtures. These experiments collectively provide evidence for multiple conductance pathways in lobster olfactory receptor cells. The functional significance of having more than one conductance underlying the depolarizing receptor potential is as yet unclear. Large, graded depolarizing receptor potentials can be routinely recorded in the soma of more than 50% of the cells challenged with broad-spectrum odorants such as TetraMarin extract. Lobster olfactory receptor cells appear to have electrical properties like those found in the olfactory receptor cells of other species, many of which are common to small neurons in general. They also share many of the morphological features of olfactory receptor cells in other organisms. Lobster olfactory receptor cells are proving to be a useful model for studying chemosensory transduction, not only from a biophysical, but also a biochemical perspective.
