Inconsistent findings

• research on the relationship between amygdala volume and the severity of ASD has mixed results
• Howard et al


  an increased volume in the amygdala in those with ASD
• Pierce et al


  found a decreased volume in amygdala in those with ASD in adults
• Herbert et al


  found contrasting findings,children with ASD have a smaller amygdala volume
• amygdala function becomes unclear,casts doubt of the validity of the theory
