The heart rules the head when we make financial decisions
Our ‘gut feelings’ influence our decisions, overriding ‘rational’ thought, when we are faced with financial offers that we deem to be unfair, according to a new study.

Acid in the brain: Team develops new way to look at brain function
University of Iowa neuroscientist John Wemmie, M.D., Ph.D., is interested in the effect of acid in the brain.

The findings also suggest that eating behavior is related to brain dopamine pathways involved in addictions.
