Extract:

The neural basis of unconditional love reports a functional magnetic resonance imaging study where human subjects viewed pictures of individuals with intellectual disabilities and instructed to either just view the pictures or "to self-generate a feeling of unconditional love toward the individuals depicted".

The study has been critically commented by Thomas Ramsøy on his blog.[1]

[edit] Critique

  1. The Talairach atlas is referenced, but is not a MRI stereotaxic space. The template is not clear, but as SPM2 is used it is probably MNI space.
  2. Small volume correction is used.
  3. It is not stated which form of multiple comparison correction is used. Guessing from the used of SPM2 it is probably random field corrected over voxels and voxels values.
  4. Under "Data analysis" section it is stated that a P < 0.005 corrected threshold was used. However, under the result section for "A posteriori correlational analyses" it is stated that a threshold on P<0.05 is used.
