Here we report that decyl-thio-trifluoropropanone also inhibited the responses of two pheromone receptor neurons of Bombyx mori to bombykol and bombykal. In contrast, decyl-thio-trifluoropropanone activated receptor neurons of the moth Imbrasia cyrtherea tuned to the pheromone component (Z)-5-decenyl 3-methyl-butanoate. However, decyl-thio-trifluoropropanone did not affect the responses of two receptor neurons of B. mori females specialized to the plant volatiles benzoic acid and linalool, respectively. These results indicate that decyl-thio-trifluoropropanone, besides inhibiting the sensillar esterase, interferes with proteins involved specifically in the excitation of pheromone receptor neurons. In binding studies with radiolabelled decyl-thio-trifuoroproparopnone, the inhibitor was bound by the pheromone-binding protein of A. polyphemus. However, the amount of decyl-thio-trifluoropropanone causing response inhibition was 300 times lower than the amount of pheromone-binding protein present in the sensilla. Since the amount of decyl-thio-trifluoropropanone adsorbed corresponded to about the maximum number of receptor molecules calculated per sensillum, we expect that decyl-thio-trifluoropropanone, probably in complex with pheromone-binding protein, competitively inhibits the pheromone receptor molecules.","PeriodicalId":15522,"journal":{"name":"Journal of comparative physiology.

Dancing and trophallactic events were recorded for bees returning from a rate feeder that provided 50% weight on weight sucrose solution at a constant flow rate of 5 microl min(-1). Bees that had danced immediately before their trophallactic contact had more recipients per trophallaxis compared with bees that did not dance before. Thus, besides information coded in dancing behavior, dance maneuvers could serve as a stimulus to increase attention of bees located on the dance floor to receive nectar. In addition, the number of bees receiving food during a trophallaxis showed a positive correlation with the probability of dancing immediately after contacting. The time from arrival at the hive to when the first or the subsequent contacts took place presented no correlation with the probability of dancing after trophallaxis. Also, the duration of a trophallaxis was positively correlated with the number of recipients per trophallaxis. These results suggest that returning foragers could receive information during a trophallactic contact with their hive mates that modify thresholds for dancing. Dance maneuvers and trophallactic contacts performed by foraging bees seem to be \"mutually\" affected.","PeriodicalId":15522,"journal":{"name":"Journal of comparative physiology.

We use the nerve discharge in the external peritentacular nerve evoked by applying a puff of conditioned odor to the nose to document crossed inhibition between left and right odor processing pathways. Responses in the external peritentacular nerve evoked by stimulating one superior nose with a conditioned odor are strongly lateralized as responses occur only on the stimulated side. Stimulating both superior noses simultaneously with the same conditioned odor yields responses in both external peritentacular nerves that resemble the sum of responses to unilateral stimulation. Simultaneously stimulating both superior noses, each with a different conditioned odor leads to strong inhibition of both external peritentacular nerve responses. The crossed inhibition is also evident if both superior and inferior noses on the same side are stimulated simultaneously. A lateral inhibitory mechanism, situated postsynaptic to odor recognition, appears to inhibit external peritentacular nerve responses if the two noses receive conflicting sensory inputs.","PeriodicalId":15522,"journal":{"name":"Journal of comparative physiology.

In the closer muscle, activation of GABA(B) receptors by baclofen reduced the mean quantal content of excitatory junctional currents by about 25%. Blocking GABA(B) receptors with CGP 55845 diminished presynaptic inhibition at a similar percentage. GABA(B) receptor-mediated presynaptic inhibition is linked to G proteins. Application of pertussis toxin eliminated about 25% of the inhibition exerted by the common inhibitory neuron. GABA(B) receptors participate in presynaptic inhibition at release boutons of the slow and the fast closer excitor at a similar percentage. In the opener muscle, presynaptic inhibition of transmitter release from the same endings of the opener excitor was about 15% stronger with the specific inhibitor than with the common inhibitor. About 10% of the presynaptic inhibition produced by either one of the two inhibitors could be abolished by blocking GABA(B) receptors. The amplitudes of the excitatory junctional currents in the opener were reduced in the presence of baclofen by about 25%, suggesting that synaptic terminals of the opener excitor are endowed with a similar percentage of GABA(B) receptors as terminals of the slow and the fast closer excitors. Baclofen had no effect on postsynaptic inhibition, indicating that GABA(B) receptors are not involved in postsynaptic neuromuscular inhibition.","PeriodicalId":15522,"journal":{"name":"Journal of comparative physiology.

Single neurons can switch from the gastric or the pyloric pattern to the cardiac sac pattern. Some of the pyloric neurons fire with the gastric pattern. All of the gastric neurons fire with the pyloric pattern, unlike those in reptantians. Proctolin activates and modulates the cardiac sac and the pyloric rhythm, and promotes reconfiguration of the networks. Neurons of the three networks have so many interconnections that they construct a multifunctional neural network like those in Cancer. This network may function in different configurations under the appropriate conditions. Several modes of interactions between the networks found in different reptantian species can apply to the penaeidean shrimp. Such interactions are general features of the stomatogastric nervous system in decapods. Phylogenetic differences among the decapod infraorders are seen in the number and orientation of muscles and the innervation pattern of muscles. The multifunctional networks have existed in the most primitive decapod species, and types of configurations of the networks would have evolved to produce a wide range of motor patterns as the foregut structure has become complex.","PeriodicalId":15522,"journal":{"name":"Journal of comparative physiology.

Included in the radiocollared field group were 30 chipmunks with supra-chiasmatic nucleus-targeted lesions, 24 surgical controls, and 20 intact controls. An additional 17 chipmunks were used in a laboratory study as lesion-calibration controls to correlate degree of circadian arrhythmicity with extent of supra-chiasmatic nucleus deletion. Survival was documented in the field by daily radio tracking and by regular trapping censuses except during winter hibernation. A significantly higher proportion of supra-chiasmatic nucleus-lesioned than surgical control chipmunks or intact controls were killed by weasel predation during the first 80 days after repatriation. A 28-h continuous census found no surface activity of any chipmunks during hours of darkness. However, episodes of nocturnal movement were detected within the permanent dens by radio telemetric data logging, especially in supra-chiasmatic nucleus-lesioned animals. Excavation and mapping of six chipmunk burrow systems aided in the interpretation of the telemetric activity data. Nighttime restlessness of supra-chiasmatic nucleus-lesioned animals may have acted as a clue to the predator for locating its prey.","PeriodicalId":15522,"journal":{"name":"Journal of comparative physiology.

Twenty compounds belonging to four different chemical substance classes were tested, both in the laboratory and in the field. In the laboratory, the bats (Glossophaga soricina) approached odour sources spontaneously and without preceding experience. Without ever receiving any reward they preferred the scent of a sulphur-containing compound, dimethyl disulphide, to several other odour components emitted by bat-pollinated flowers, and to scentless controls. In the field, at La Selva station in the tropical lowland rain forest of Costa Rica, G. commissarisi were attracted by two sulphur-containing compounds, dimethyl disulphide and 2,4-dithiapentane, to visit artificial flowers filled with sugar water. Thus, in nectarivorous bats the sense of smell obviously plays an important role in searching for and localising food sources, and even single components of the scent bouquets of bat-pollinated flowers are attractive.

The array could be rotated to cover the sphere around the cicada. The sound was analysed in one-third-octave bands with centre frequencies from 3.15 kHz to 16 kHz, the frequency range of the calling song. The seven cicadas studied had very similar spatial radiation patterns, but somewhat different emitted sound powers (range 190-440 nW, mean 280 nW, at 22 degrees C). At low frequencies, the pattern of sound radiation was close to spherical. At higher frequencies, systematic deviations from a spherical pattern were evident. The deviations were of the order of magnitude expected for monopolar sound sources located on sound-shielding bodies. We conclude that, although the singing cicada produces a quite complex acoustic near field, it behaves as a monopole in the far field. These findings are compared with data from a singing grasshopper of similar size, which in the far field behaves as a multipole.","PeriodicalId":15522,"journal":{"name":"Journal of comparative physiology.

By measuring visual field sizes and optical axes in different parts of the dorsal rim area, we assessed the optical properties of the ommatidia. Due to the large angular sensitivities (median about 20 degrees) and the high sampling frequency (about 1 per degree), the visual fields overlap extensively, such that a given portion of the sky is viewed simultaneously by a large number of ommatidia. By comparing the dye markings in the retina and in the optic lobe, the axon projections of the retinula cells were examined. Receptors R1, R2, R5 and R6 project to the lamina, whereas R7 projects to the medulla. The microvilli orientation of the two projection types differ by 90 degrees indicating the two analyser channels that give antagonistic input to polarisation-sensitive interneurons. Using the retinal marking pattern as an indicator for the quality of the intracellular recordings, the polarisation sensitivity of the photoreceptors was re-examined. The polarisation sensitivity of recordings from dye-coupled cells was much lower (median: 4.5) than that of recordings in which only one cell was marked (median: 9.8), indicating that artefactual electrical coupling between photoreceptors can significantly deteriorate polarisation sensitivity. The physiological value of polarisation sensitivity in the cricket dorsal rim area is thus typically about 10.","PeriodicalId":15522,"journal":{"name":"Journal of comparative physiology.
