Human fear conditioning is related to dopaminergic and serotonergic biological markers.

Behavioral neuroscience - 1 Apr 2001

Garpenstrand H, Annas P, Ekblom J, Oreland L, Fredrikson M

Abstract excerpt

Biological markers for acquisition and extinction of fear conditioning were studied in 40 individuals selected for displaying either good or poor acquisition of fear conditioning. as estimated by the skin conductance response. Participants with a short serotonin transporter (5-HTT) promoter allele or low monoamine oxidase activity in platelets (trbc-MAO) displayed better acquisition than those with only long...
