Developmental increase in AMPA/NMDA ratio in the PrV. (A) An example of measurement of compound EPSCs at different holding potentials. The amplitude at 8 ms shows an AMPA-like linear voltage-dependency. The amplitude at 30 ms displays a typical NMDA voltage-dependency. (B) Example records illustrating the increase in AMPA/NMDA ratio at the second postnatal week in the normal PrV (upper vs. lower traces). (C) Example records showing the developmental increase in AMPA/NMDA ratio in the denervated PrV (upper vs. lower traces). (D) Linear correlation and regression between the AMPA/NMDA ratio and postnatal ages in the normal (closed circles, dashed line) and denervated barrelette neurons (open circles, dotted line). The analysis of covariance (ANCOVA) shows the slopes and intercepts of regression lines are the same (p=1.00). (E) Linear correlation and regression between the AMPA/NMDA ratio and postnatal ages in the normal (closed circles, dashed line) and denervated interbarrelette neurons (open circles, dotted line). The analysis of covariance (ANCOVA) shows the slopes and intercepts of regression lines are similar (p=0.58).
