In sum, the results of the present investigation, and probable role of the hippocampal complex in transfer/transformation of stimulus function, underscore the broad functionality of SE based preparations.
Of these two functions, the first or fast function can be thought of as an organ feed or stimulus function consisting of rapidly changing blood pool background within the organ.
In a second step, a calculated convolution function of an assumed impulse response function and the stimulus function was fitted with the measured [deoxy-Hb] and [Cyt-Ox] curves to obtain amplitude, time delay, and time constant parameters.
The regressor was created by convolving a stimulus function with an assumed hemodynamic response function (HRF), where the function was shifted based on the phase determined from the fourier analysis of the polar angle scans.
We used a standard rapid-event related fMrapid-event relatedh evoked hemodynamic responses to stimulus events are estimated separately by convolving a canonical hemodynamic response fMRItion with approachus functinn encoding the onsets for each event.
Equation (9) implies that when the value of the stimulus function in one direction is much larger than the value in the other direction (i.e., g1 ≫ g2 or g1 ≪ g2), then a uniaxial fiber distribution (i.e., β p → 0) is obtained.
