  • Values are mean ± SD and [minimum–maximum]. Numbers preceded by > and < sign refer to column number with statistically significant differences and to the direction of the difference. The f–I slope values are also given separately for FSLFI and FSC cells in the fast spiking cells column as these two subclasses of fast spiking cells showed a significant difference for this variable.
