31 Jan, 2011 - A potential mechanism for the effects of omega-3 on mood have been suggested by a new study published in Nature Neuroscience. The research studied mice fed a life-long diet imbalanced in omega-3 and omega-6 fatty acids, finding that in omega-3 difficient mice certain receptors in the central nervous system – which play a strategic role in neurotransmission – suffer a complete loss of function. The researchers said that this neuronal dysfunction was accompanied by depressive behaviours among the malnourished mice.
