The response of a van der Pol oscillator to a sinusoidal input with a sinusoidally varying amplitude is discussed.
For example, the activity of the primary motor cortex is continuously modulated by somatosensory information (here abstracted with a sinusoidal input), or by motor efferent copies, during movement performance.
Examples of flow profiles are given to show that the criterion of a "sinusoidal" input flow profile required by USP is not a sufficiently accurate characterization at the inlet as numerous profiles can be conceived which have the same average flow rate.
Networks were driven with a sinusoidal input (Fig. 2 A), as elicited by a sinusoidal grating in layer 4 of cat visual cortex (Fig. 1 A).
bias for a sinusoidal input.
The model is driven with a sinusoidal input of 1 V.
In one experiment, a sinusoidal input of amplitude ±300 μrad was employed at 10 Hz.
Let us consider the case of a sinusoidal input with frequency higher than the bandwidth.
As mentioned previously, we chose a sinusoidal input with a particular frequency to help discriminate between the models.
For example, if demanding a sinusoidal input may be unrealistic in a laboratory setting, and an optimal input in a smaller input function space is practically required, such constraints can be added to the nonlinear optimization criteria.
