Optical densitometric measurements of reaction product of CO (A and F) and immunoreaction product of GluN1 (B and G), GABAARα1 (C and H), BDNF (D and I) and TrkB (E and J) in single, non‐deprived and deprived layer V neurons are shown for the three time points (P23, P32 and P39) after 4 days of MD without or with in vivo 7,8‐DHF or ANA‐12. Comparisons that have reached statistical significance are indicated by asterisks. Changes were most striking at P32. All ***
