Figure 7.
The role of IPSPs and EPSPs in promoting submillisecond firing coordination. A, C, Scatterplots of JSSI values versus the ICS for all SOM–FS (A) and FS–FS (C) pairs. Symbols representing bidirectionally connected pairs are filled gray. The linear regression lines apply to all data points and have r2 values of 0.50 (A) and 0.35 (C). B, D, The effect of blocking fast glutamate receptors (APV/CNQX), GABAA receptors (GBZ), or both (APV/CNQX/GBZ) on the JSSI, for nine SOM–FS pairs (B) and seven FS–FS pairs (D). Symbols representing the same pair are connected by lines. Note that blocking ionotropic glutamate receptors had little effect on synchrony, whereas blocking GABAA receptor profoundly reduced it.
