Abstract excerpt
Fyn-tyrosine-kinase-deficient mice exhibit increased fearfulness. To elucidate the neural mechanisms of their emotional defects, we compared fyn(-/-) and fyn(+/-) mice by behavioral analysis of conditioned fear and by functional neuroanatomical analysis of the distribution of highly responsive neurons associated with conditioned fear. The mice were exposed to the auditory conditioned stimulus paired with electric...
