Figure 5: Antagonist analysis by PCA. PCA scores plot for various concentrations of glutamate and 0.05mM DNQX (Js) and 0.05mM NBQX (Ks) combined for antagonist evaluation. The area on the clustered PCA plots of Glu samples is indicated by dotted line and the area of antagonist (NBQX, DNQX) is indicated by a solid line.
