The authors have used a neural network to regress between inputs from NSS-based spectral amplitude fall-off curves in combination with positional similarity measure of wavelet coefficients and the corresponding quality value.
In contrast, in medical images like mammograms, amplitude falls more rapidly with frequency, roughly with a slope of − 1.5 (Burgess et al., 2001).
The time of the zero-crossing is qualified as a spike event if the peak amplitude falls above a given threshold and outside of a given refractory period after the last spike.
Stimulation once triggered was sustained until beta amplitude fell below threshold again (Fig 2).
This motion amplitude falls well within the range of normal steady fixation consisting of tremor, drift, and microsaccades [ 17].
Here, the power at which the peak-to-peak derivative amplitude falls to half the value expected for a linear response, P50, is the value reported.
Event words from the PET scanner were included in the new list whenever the amplitude fell between the L and U thresholds defined in Materials and Methods.
Because action potential amplitude falls off with distance, it is possible to use the unique combination of amplitudes from the 7 electrodes to triangulate the locations of the neurons (Litke et al. 2004).
There would be no perceptible delay in the peak of the pulse arriving at different parts of the synapse although, of course, the amplitude falls with distance and does not quite achieve that seen with a continuous NO output.
Average amplitude fell from 2.27 ± 0.34 for 37 oscillations recorded under control conditions to 0.99 ± 0.11 in 37 oscillations recorded from 20 to 40 s after the start of nifedipine application (P < 0.001).
