Figure 2. Impaired learning of neutral cue in human Met allele carriers.
Elevated skin conductance response (SCR) to the cue never paired with the aversive stimulus during fear conditioning as a function of time in Met allele carriers (VM) relative to nonMet allele carriers (VV). All results are presented as a mean ± SEM. *p < 0.001, Student’s t test. VV = Val/Val; VM = Val/Met.
