Figure 7. Inhibition of field potential and CBF responses by AMPA or NMDA receptor blockade.

Figure 7

Effect of glutamate receptor blockade on cerebral blood flow (CBF), field potential (FP) responses and neurovascular coupling. Ordinate indicates inhibition of CBF response while abscissa indicates inhibition of FP responses. Dashed line has slope of −1. Data points indicate maximal inhibition of CBF and FP amplitudes. CNQX (n = 6) and CNQX + MK801 (n = 4) produced proportional decreases of FP and CBF amplitudes. MK801 (n = 6) given alone, and GYKI (n = 6), a reversible and transient AMPA receptor antagonist, attenuated the CBF increases without a corresponding decrease of FP amplitude.
