Isointensity curve and comparison between the responses of stimuli in the control and adaptation sequeces for the population of neurons.

<p>A. The population isointensity curve of 167 neurons that their firing rates were normalized and they were aligend to each other according to their adapter and four neighboring frequencies. Error bars are the standard error of the mean (s.e.m.). B. The scatter plots show the firing rate in control sequence vs. adapting sequence and the histogram of neural response changes for the adapted frequency (middle plot) and higher and lower neighboring frequencies in 60 dB. Dots indicate the neural responses of each neuron averaged across trials. Each dot placed upper the red line, demonstrates that the firing rate of that neuron in control sequence (FR-C) is more than the firing rate of it in adapting sequence (FR-A).
