The reliability of nonlinear least-squares algorithm for data analysis of neural response activity during sinusoidal rotational stimulation in semicircular canal neurons
Description of neural response activity and fitting functions in frequency test (A) and amplitude test (B). The upper black solid curves indicated the dynamic head instantaneous angular velocity. The black circles in the medium and bottom rows show the dynamic instantaneous neural response activity (instantaneous fire rate) to the corresponding stimulation for regular and irregular SCNs separately. The red solid curves over the data of neural response activity indicate the fitting function calculated by nonlinear least-squares algorithm with sinusoidal model.
