Our brain is made mainly of fats and has a ratio of 1 (omega 3) : 1 ( omega 6) . So I think it's very important to take both at the same time.
The reason why Fish oil appeared to work for many trials is because the people were already deficient in both the unadulterated and unprocessed fatty acids eating a bat diet. So when you have one useful fatty acid introduced to the body system . Your brain is going to love it but the queston remains - Is this the optimal choice ( esp for organs, muscle and skin which demand more N-6) ?
The fatty brain

The membranes of neurons – the specialized brain cells that communicate with each other – are composed of a thin double-layer of fatty acid molecules. Fatty acids are what dietary fats are composed of. When you digest the fat in your food, it is broken down into fatty acid molecules of various lengths. Your brain then uses these for raw materials to assemble the special types of fat it incorporates into its cell membranes.

In a Canadian study of human breast milk, trans fatty acids (TFAs) averaged 7.2% of the total fatty acids. Partially hydrogenated vegetable oils were determined to be the major source of these unnatural fats. Also, levels of LA (linoleic) and ALA were inversely related to the total TFAs, indicating that the elevation of TFAs in Canadian human milk is at the expense of essential omega-3 and omega-6 fatty acids.3

Do u see how bad is it to have 'experts' warning us on popular press about the danger of fats without differentiating the good and bad one ?
The ultimate brain blocker : Trans fats
The Human Brain - Fats Quote:
Trans fatty acids found in foods like french fries, margarine, potato chips and anything else with partially hydrogenated oil disrupt communication in your brain. Trans fatty acids are rarely found in nature and are mostly man made.
Studies show that the trans fatty acids we eat do get incorporated into brain cell membranes, including the myelin sheath that insulates neurons. They replace the natural DHA in the membrane, which affects the electrical activity of the neuron.
Trans fatty acid molecules disrupt communication, setting the stage for cellular degeneration and diminished mental performance.
