This telescope contains frequency-sweep-type spectrum analyzers with the time and frequency resolutions of 500 ms and 500 kHz, respectively.
A TOBSY (Baldus and Meier, 1996) mixing time of 6.6 ms and 10 kHz GARP (Shaka et al, 1985) decoupling were employed.
The shortest response latency of this neuron to 19 kHz was observed at 75 minutes (17.16±0.58 ms), to 20 kHz at 83 minutes (11.18±0.6 ms) and to 21 kHz at 64 minutes (12.50±0.71 ms) after the onset of ESAI.
Long-range C C contacts were obtained with a series of 2D proton-assisted recoupling (PAR) experiments optimized using a C radiofrequency field of ∼50 kHz and a H radiofrequency field of ∼55 kHz for mixing times between 8 and 15 ms and employing 83 kHz TPPM H decoupling during acquisition and evolution periods.
We then produced spectrograms using AviSoft 4.2 (FFT-length 512, FFT-length 512n—1 ms and frequency range—0–8 kHz) and saved time as.txt-files.
A 50-kHz call (length, 20 80 ms; frequency, 35 70 kHz) and a 40-kHz call have been described [1].
6 This coherence block can, for example, have the dimensions of T c =10 ms and W c =100 kHz.
This channel can be approximately decomposed into parallel time-frequency channel using WH sequences as explained in Section 2. We assume in the following that the grids parameters are chosen such that TF = 1.25, where T = 0.1 ms and F = 12.5 KHz.
The sampling rate, frame shift, and window length are 8 kHz, 5 ms, and 25 ms, respectively.
The time interval between the first two components of the composite EPSC remained constant during recording and ranged from 0.3 ms (3 kHz filter) to 3.1 ms. Since a composite EPSC was elicited by one spike, one could rule out the possibility that the components appeared due to variation in the presynaptic spike initiation time.
