Particular interests of Dr. Cohen's group include
abnormalities of bioenergetics and mitochondrial function in psychiatric and mood disorders and
abnormalities of connectivity and
myelination, especially in those with schizophrenia.
As a general limitation that applies to the current DTI research at large we recognise that FA differences between groups could be a result of several factors (
myelination, axon density, axon diameter, membrane permeability, or even axonal orientation and fiber crossing) and that simple DTI tensor calculations as employed in our study may not conclusively link the regional
abnormalities to any specific mechanism (Jones et al. 2013).
