I recently co-authored the largest functional brain imaging study in history, with 21,000 subjects, showing that a particular type of brain imaging, single-photon emission computed tomography (SPECT) can distinguish PTSD from TBI. We were thrilled to be selected by Discover Magazine as #19/100 for their Top Stories of 2015.

Probably the two most frequently confused psychiatric disorders, schizophrenia and dissociative identity disorder, are worlds apart in their core features.
Dementia is widely regarded as the coming public health crisis of an aging population, but what is it?
Everybody knows that elevated dopamine is the reason we experience pleasure, right?
It seems like a paradox: we prescribe stimulants for kids who are hyperactive. Once we understand the neurobiology of ADHD, this approach makes a lot more sense.
What is Attention Deficit Hyperactivity Disorder? What are its symptoms? How common is it?
To understand the Oedipus complex and how it came to have such a central role in psychoanalytic thought, let’s first turn to its inspiration, Sophocles’s tragedy, Oedipus Rex, or Oedipus the King, a play Aristotle referred to as “The purest classical tragedy.”
