Abstract: In vivo whole-cell recordings combined with an intracellular N-methyl-d-aspartate receptor (NMDAR) blocker and membrane hyperpolarization are used to examine the contribution of dendritic NMDAR-dependent regenerative responses to the angular tuning of layer 4 neurons; the results show that active dendritic processing sharpens the sensory responses of cortical neurons in vivo.
