“…Intracellular recording in the integrative zone (dendrites) of the L3 neuron frequently results in increased ''spontaneous'' firing that would be difficult or impossible to distinguish from impulses created by the prolonged response. Navia et al (2003) clearly demonstrated that L3, recorded intracellularly and stained with Lucifer yellow, produced both the previously described immediate response (Atkins et al,'89) and the prolonged response. Only two pairs of neurons that arise in the prothoracic ganglion and send an axon up the cervical connective have been clearly identified and described in any of the gryllid species (L1 and L3 in A. domesticus, AN1 and AN2 in several other gryllids) that encode behaviorally important features of the CSs at carrier frequencies and intensities that are behaviorally relevant to phonotaxis.…”

“…Post-stimulus time (PST) histograms and spiking rates were calculated. To avoid counting spikes of the immediate response or the reduction of the prolonged response by the delayed inhibition of L3's responses (described by Navia et al, 2003), spiking rates were determined at all intensities by measuring the last 300 ms of the interval between chirps.…”

“…1B,D). This paper describes another, more tonic, prolonged response (identified and described as an additional response by L3s to model CSs by intracellular recording and staining with Lucifer yellow, Navia et al, 2003) which occurred during and following each chirp at a much slower spiking rate than the immediate response to the syllables (in response to 5 kHz CSs, Figs. 1A, 2).…”

“…To evaluate these prolonged responses more effectively, extracellular recordings from L3's axon in the neck connective were performed to eliminate possible damage (depolarization) caused by intracellular recordings (Navia et al, 2003). Extracellular recordings showed that the prolonged response had a slow onset that takes 3-8 sec following the initial chirp to reach a maximum spiking rate and 6-20 sec following stimulation (n=10) for the response to decay to a level of activity seen before the onset of stimulation (an example is shown in Fig.…”

“…The L3 auditory interneuron is also found in the prothoracic ganglion of female A. domesticus and is involved in the female's phonotactic response (Stout et al,'85;Atkins et al,'84,'92). L3 exhibits two different responses to model CS: an immediate response which encodes the syllables of the call (Atkins et al,'89;Henley et al,'92), and a prolonged response which does not encode the temporal features of the call (Navia et al, 2003).…”

L3, an auditory interneuron in the prothoracic ganglion of female crickets (Acheta domesticus) exhibited two kinds of responses to models of the male's calling song (CS): a previously described, phasically encoded immediate response; a more tonically encoded prolonged response. The onset of the prolonged response required 3-8 sec of stimulation to reach its maximum spiking rate and 6-20 sec to decay once the calling song ceased. It did not encode the syllables of the chirp. The prolonged response was sharply selective for the 4-5 kHz carrier frequency of the male's calling songs and its threshold tuning matched the threshold tuning of phonotaxis, while the immediate response of the same neuron was broadly tuned to a wide range of carrier frequencies. The thresholds for the prolonged response covaried with the changing phonotactic thresholds of 2- and 5-day-old females. Treatment of females with juvenile hormone reduced the thresholds for both phonotaxis and the prolonged response by equivalent amounts. Of the 3 types of responses to CSs provided by the ascending L1 and L3 auditory interneurons, the threshold for L3's prolonged response, on average, best matched the same females phonotactic threshold. The prolonged response was stimulated by inputs from both ears while L3's immediate response was driven only from its axon-ipsilateral ear. The prolonged response was not selective for either the CS's syllable period or chirp rate.

Female crickets (Gryllus pennsylvanicus), caught in the field as nymphs, responded as adults in the laboratory with selective phonotaxis to model calling songs (CSs) that reproduced the dominant carrier frequencies and syllable periods (SPs) characteristic of the male's natural calling song. Extracellular recordings demonstrated two types of auditory interneurons in the female's cervical connectives that were very similar to the AN1 and AN2 neurons previously described in other gryllid species. The AN2 neuron responded to model CSs with a phasically encoded immediate response, and a more tonically encoded prolonged response. AN2's immediate response exhibited SP-dependent decreases (termed decrement) in its responses to sequential syllables of the CS that were greatest to CSs with the shortest SPs and diminished as SPs were lengthened, resulting in an SP-dependent habituation. Picrotoxin application transformed this SP-dependent habituation by AN2 to SP-selective responses in which the degree of decrement was greatest to SPs that were most phonotactically attractive. AN2's prolonged response was most sensitive to 5 kHz CSs and correlated with the carrier frequency tuning for the thresholds of phonotaxis by females. Thus, in females, AN2's immediate (in the presence of picrotoxin) and prolonged responses were selectively tuned to the SPs and carrier frequencies of the male's calls that were most attractive behaviorally. AN1's responses at threshold were also tuned to the dominant carrier frequencies of the male's CS.

Sound processing properties for calling song (CS) models, as described for the prothoracic L3 auditory neurone in Acheta domesticus, are investigated for the homologous auditory neurone 2 (AN2) in female Gryllus bimaculatus De Geer. AN2 of G. bimaculatus responds selectively to the syllable period (SP) of models of a male CS. The selectiveness of this response parallels the selectivity of phonotaxis females perform in response to the same SPs. Both, the responses of AN2 and female behaviour show clear interindividual variability. The SP‐selective responses of AN2 result from an SP‐dependent reduction in the spiking to subsequent syllables of the model CSs, measured as the percentage decrement. This SP‐dependent response does not primarily result from inbuilt properties of the AN2 membrane. Rather, it is dependent on inhibitory input to the AN2. However, clear inhibitory postsynaptic potentials in dendritic recordings of the AN2 are not encountered. This immediate response of AN2 to CSs is followed by an increased rate of tonic firing between stimulus CSs, which is termed the prolonged response, and is dependent on the carrier frequencies that make up the male CSs. With stimulation on the contralateral side of the soma of AN2s, more than 50% of AN2s exhibit a prolonged response. However, with stimulation from the ipsilateral side of the soma, most AN2s exhibit a prolonged response. The prolonged response of AN2 at 5 kHz may be even more sensitive than the immediate response. Thus, the AN2 neurone could provide a basis for phonotaxis that is selective for both the SPs and the carrier frequencies of potentially attractive calling songs.
