FIG. 14.
Top panels are amplitude envelopes (top) and spectrograms (bottom) for sounds presented to awake mustached bats. Bottom panels are PSTHs (bin width = 5 ms) representing neural responses to 200 repetitions (2/s) of the sound in the corresponding top panel. All responses shown here originate from the same DSCF neuron. Amplitude envelopes and spectrograms of the CF at BFlow are shown, respectively, as unfilled, outlined rectangles and white outlined bars; amplitude envelopes of CFs at BFhigh are shown as solid, filled rectangles and bUFM. A: top: spectograms by black bars is the best call of the neuron. Bottom: PSTH the neuron's response to the bUFM call. *This axis range differs from the adjacent axis in E. Note that this panel contains the unit number. B: top: band-pass filtered bUFM call fragment paired with the BFlow (25.60 kHz). The call fragment is quasi-linear (slope = ∼0.63 kHz), centered on the BFhigh (59.19 kHz), and has a 5-kHz bandwidth (61.69–56.69 kHz). Bottom: PSTH depicting the response of the neuron to the call fragment and BFlow. C: top: band-pass filtered bUFM call fragment alone. Call fragment is parametrically identical to its description in B. Bottom: PSTH depicting the response of the neuron to the call fragment. D: top: the BFlow presented alone. Bottom: the neuron's PSTH depicting the response to the BFlow. E: top: the BFlow paired with the BFhigh. Bottom: PSTH response of the neuron to the BFlow and BFhigh. F: top: reversed band-pass filtered bUFM call fragment paired with the BFlow. All stimulus parameters are the same as in B except for call fragment direction. Bottom: response to the reversed call fragment and BFlow. G: top: reversed band-pass filtered bUFM call fragment alone. All stimulus parameters are the same as in C except for call fragment direction. Bottom: response to the reversed call fragment alone. H: top: the BFhigh presented alone. Bottom: PSTH depicting the neuron's response to the BFhigh. All stimuli presented at BA.
