Cortical STPP. (A) Two photon image of a pyramidal neuron (Ai) and its basal dendrite with priming (blue color)/gating (green outline) glutamate uncaging spots on the individual spines in a basal dendrite (Aii). (B) The representative responses to priming plus gating (cyan trace) and gating alone (green trace) glutamate uncaging were shown as photoactivated EPSPs. When the priming stimulus preceded the gating stimulus, the facilitated response (cyan trace) was elicited in the electrical recording at the cell body (Bi). (C) NR2B selective blocker, Ifenprodil, completely blocked the neuronal facilitation (Ci). Population data of control (Bii, n = 12 cells/4 animals) and Ifenprodil (Cii, n = 5 cells/4 animals) in electrical recording of the cell body. **p < 0.01; n.s, P > 0.05.
