The influence of the SFM carrier frequency was also evaluated in filter units. In some units, the particular carrier frequency used was not critical for evoking locked discharges so long as the signal encroached upon the unit's tuning curve. In the majority of filter units, however, there was...
1A.i). We then explore the functional roles of our neuromodulated learning rule in a neural network (Fig. 1A.ii). Given the established role of dopamine as a reward signal and the increased release of acetylcholine during exploratory behaviours, we model navigation, specifically a task where ...
An EDFA boosts the power of the beat note before the output is split into two arms of equal power by a second 3 dB coupler. One output illuminates the photomixer emitter, which converts the optical beat to THz radiation. A pair of parabolic mirrors guide the THz signal from the ...
This, together with signal synchronization, suggests that the islets contain a functional pacemaker (FPM) from which excitation propagates by means of gap junctions to the rest of the islet cells (mostly beta-cells). Thus, the electric characteristics of the individual beta-cells are functionally ...
The stimu- lus signal consisted of a carrier tone of 8 kHz modulated in amplitude (95% depth) at a rate of 115 Hz. This carrier tone was selected since previous rat studies have demonstrated a peak of sensitivity at 8 kHz.19-21 This carrier and others lower than 8...
At step 108, the parallel processing unit encodes chroma information and modulation information derived from the image decomposition algorithm into a video signal for the mixed-primary display. The encoding may include generating a number of sub-frames, each sub-frame corresponding to one mixed-primar...
Current scanning devices rely on optical lansing to focus the image on paper onto the image plane of a "camera tube". Modern "camera tubes" are actually solid state charge coupled devices (CCD) or photo-junction sensors that convert the image into a digital signal. ...
2.2Wide bandwidth: 47 ~ 862 & 950 ~ 2410MHz working bandwidth, one fiber can transmit CATV & SAT-IF signal at the same time. 2.3Transmit 1 ~ 2 satellite signals. 2.4The optical transmitter can provide the same satellite with two polarized power supply options either with...
that ranges from 0 Hz to 1 kHz in 1 s and its mirrored version of 1 kHz to 0 Hz. Between both sweeps, flagella remained 1 s unstimulated (shown as a shorter section in the figure). The flagellar responses to sweeps (middle) were used to extract an “envelope” of the...
EEG data were recorded at 2048 Hz and were acquired referenced to linked electrodes located midway between POz and PO3/PO4 respectively and were re-referenced off-line to the average of the signal at the two mastoids. EEG data were filtered off-line (0.03–40 Hz) and downsampled ...
