Density of α₇ mRNA and [¹²⁵I]α-BTX binding-site expression in the primary barrel region of P7 pups that received a cytochemical VB lesion at P6

Cortical hemisphere	α7 mRNA (dpm/mg)		[125I]α-BTX (fmol/mg)
	IV	VI	IV	VI
Control	487.36  ± 55.93	965.89  ± 49.51	1.53  ± 0.04	1.65  ± 0.11
Lesioned	151.54  ± 85.66*	157.68  ± 68.19‡	1.02  ± 0.09†	0.74  ± 0.04‡

mRNA and binding-site density were determined at the level of layers IV and VI of control and lesioned cortical hemispheres. Animals were unilaterally lesioned on P6 as described in Materials and Methods and allowed to survive for 1 d postlesion. Data represent the mean ± SEM for three to four animals. *, p < 0.05, ^†, p < 0.01, ^‡,p < 0.001 significantly different from the control hemisphere.
