This chapter reviews data from a range of disciplines and, in particular, the comparison of lesion effects with those of anti-anxiety drugs. It presents an essentially two-dimensional picture of the neurology of defense that matches the two ethological dimensions described in Chapter 2. Small defensive distances are dealt with by lower neural levels and large ones by higher neural levels following the hierarchy: periaqueductal gray; hypothalamus; amygdala/hippocampus; cingulate cortex; prefrontal cortex. Different streams within these levels control fear and anxiety, respectively.Less
