Table 1. Protocol and Calculations Used to Separate Overall Excitatory and Inhibitory Components of Synaptic Mechanisms

MAC = minimum alveolar concentration; GABA^A=γ-aminobutyric acid receptor type A; BIC = bicuculline; eq. = equation; α=[F^e− F^con]/F^e; F^e= peak discharge frequency of the neuron during complete GABA^Aergic block with BIC; F^con= control peak discharge frequency during the prevailing basal conditions of GABA^Aergic inhibition (the level of prevailing GABA^Aergic inhibition is described by the inhibitory constant α—see text for details).
