    - aggressive and sexual behaviour. Increased activity in criminals
  4. corpus callosum

Mednick et Al
1. to test if criminal behaviour is linked to nature or nurture
  1. Denmark 1400 adopted male criminals. Compared criminal records of biological and adoptive parents
    1. neither bio / adoptive = 13.5%
    2. only adoptive = 14.7%
    3. only bio = 20%
    4. both = 24%
    5. strong genetic component. Did not totally rule out effect of environment
      1. convictions may not be accurate
      2. contamination effect
      3. androcentic / gender and cultural bias
