Fig. 5

Blocking of NMDA receptors by AP-5 caused a significant decrease in TCC neuronal responses. Vibrissal (V) and GON (N) responses were halved by AP-5 (50 μM). In addition, the GON-evoked facilitation was blocked by AP-5 and unmasked a GON-evoked inhibition. * p < 0.05; *** p < 0.0001. All values are expressed as percentages with respect to the corresponding basal responses before AP-5 application
