Figure 1: BF of the Multiunit Response Shifts with Intensity.

From: Bidirectional Shifting Effects of the Sound Intensity on the Best Frequency in the Rat Auditory Cortex

Figure 1

(A) Schematic of the recording setup. Right panel, track of the recording tungsten electrode. Scale bar, 200 μm. (B) An example of a tonotopic map of the primary auditory cortex. Each dot represents a recording site. The color represents the CF. A cross indicates no response to white noise at 70 dB SPL. D, dorsal; R, rostral. A1, primary auditory cortex. (C) Example of the TRFs with a low (left), middle (middle), and high (right) CF. The color represents the number of spikes. The white stars indicate the BF at each intensity level. THR, intensity threshold. The horizontal arrows indicate the difference between the BF at 70 dB SPL and the BF at the threshold level. (D) Example TRFs obtained in awake rats with their heads in a fixed position.
