“…Heretofore concepts of pattern coding by olfactory receptors have emphasized the differences in the total changes in spike frequency from one cell to the next (Boeckh, 1967;Schoonhoven & Dethier, 1966;Dethier, 1967). The direction and magnitude of the changes reflect differences in sensitivity among the cells.…”

“…The minimum sensory requirement for this accomplishment is a specific, narrowly tuned olfactory receptor. A number of such "specialists" (e.g., the grass receptor of Locusta, the queen substance receptor and the Nasanov pheromone receptor of drone honeybees, the carrion receptors of Calliphora and Thanatophilus, the bombykol receptor of Bombyx) have been discovered by electrophysiological methods (Boeckh, 1962(Boeckh, , 1967Boeckh, Kaissling & Schneider, 1965;Lacher, 1964;Lacher & Schneider, 1963;Schneider, 1957Schneider, , 1962Schneider, , 1963Schneider, , 1969Schneider & Boeckh, 1962;Schneider, Block, Boeckh & Priesner, 1967;Schneider, Lacher & Kaissling, 1964).…”

Extracellular electrophysiological recording from olfactory receptors in the antennae of tobacco hornworm larvae (Manduca sexta (Johan.)) has revealed that cells respond differentially to different odors by changing latency, rate of increase of frequency of firing, rate of adaptation, and alternation of frequency increase and decrease. The resulting temporal patterns of spike activity could function as a code to allow for discrimination among various plant odors.It is well-known that insects are able to detect single odors which have special behavioral significance. The minimum sensory requirement for this accomplishment is a specific, narrowly tuned olfactory receptor. A number of such "specialists" (e.g., the grass receptor of Locusta, the queen substance receptor and the Nasanov pheromone receptor of drone honeybees, the carrion receptors of Calliphora and Thanatophilus, the bombykol receptor of Bombyx) have been discovered by electrophysiological methods

“…First, the pheromone-induced increase in cGMP concentration shows no relation to the dose-response behavior of the receptor potential amplitude (Schneider et al, 1967;Zack, 1979;Kaissling, 1986Kaissling, , 1987Zack Strausfeld and Kaissling, 1986;Kaissling et al, 1987). Second, the increased cGMP level persists for at least 10 min in intact animals and at least 30 min in isolated antennae, although the receptor potential returns within about 5 set after termination of the stimulus to half its resting value (Zack, 1979;Kaissling et al, 1987).…”

“…The results are discussed in the context of electrophysiological responses of the olfactory receptor cells (Schneider et al, 1967;Zack, 1979;Kaissling, 1986Kaissling, , 1987Zack Strausfeld and Kaissling, 1986;Kaissling et al, 1987). Additional electrophysiological measurements were made to study the changes in concentration of cyclic nucleotides and recovery after adaptation under identical stimulus conditions in intact animals and isolated antennae.…”

Cyclic GMP levels and guanylate cyclase activity in pheromone-sensitive antennae of the silkmoths Antheraea polyphemus and Bombyx mori

et al. 1990

Female sex pheromones applied to freshly isolated, living antennae of male Antheraea polyphemus and Bombyx mori led to an increase of cGMP. A 1:1 mixture of 2 pheromone components of Antheraea polyphemus blown for 10 sec in physiological concentrations over their antennal branches raised cGMP levels about 1.34-fold (+/- 0.08 SEM, n = 23) from a basal level of 3.0 +/- 0.6 (SEM, n = 20) pmol/mg protein. Similarly, bombykol elicited a 1.29-fold (+/- 0.13 SEM, n = 23) cGMP increase in antennae of male Bombyx mori from a basal level of 2.7 +/- 0.5 (SEM, n = 24) pmol/mg protein. No cross-sensitivity was found with respect to pheromones from either species. In antennae of female silkmoths, the cGMP response was missing upon stimulation with their own respective pheromones according to the known lack of pheromone receptor cells in the female. cAMP levels in the male antennae of 14.2 +/- 2.9 (SEM, n = 4) pmol/mg protein in A. polyphemus and 15.0 +/- 3.0 (SEM, n = 5) pmol/mg protein in B. mori were not affected by pheromone stimulation. Within 1–60 sec, the extent of cGMP increase in B. mori was independent of the duration of pheromone exposure. The levels of cGMP in pheromone- stimulated antennae of both species remained elevated for at least 10 min, i.e., much longer than the duration of the receptor potential measured in single-cell recordings. Guanylate cyclase activity was identified in homogenates of male and female antennae from both species. The Km of the guanylate cyclase from male B. mori for the preferential substrate MnGTP was 175 microM.(ABSTRACT TRUNCATED AT 250 WORDS)

“…In this section, electrophysiological recording from insect antennae with different methods using various micro devices will be introduced, which are mainly divided into two categories: electroantennogram (EAG) measurements and FET-based methods. EAG has become one of the most commonly used and well-established methods for the measurement of insect antennae in response to the chemical volatile compounds since its first report in 1955 [12,13]. There are mainly two types of EAG measurement modes.…”
