Tail amputation has no effect on DHPG-LTD in the IC. (A and B) Pooled data showing the comparable magnitude and temporal progression of DHPG-LTD between sham control (superficial layer: n = 7 slices/7 mice, A; deep layer: n = 8 slices/8 mice, B) and tail amputation (superficial layer: n = 9 slices/9 mice, A; deep layer: n = 9 slices/9 mice, B) groups. Sample fEPSP recordings taken at the times indicated by the corresponding numbers are shown above the plot. Calibration: 100 μV, 10 ms. Horizontal bars denote the period of DHPG application. (C) The induction ratio of DHPG-LTD in either superficial layer or deep layer does not differ between the two groups (sham control: n = 8 slices/8 mice; tail amputation: n = 9 slices/9 mice). NS, no significance. Error bars represent SEM.
