The electroencephalogram (EEG) is a widely used noninvasive method for monitoring the brain. It is based upon placing metal electrodes on the scalp which measure the small electrical potentials that arise outside of the head due to neuronal action within the brain. Its key benefits compared to other brain imaging techniques are that it has a very high time resolution – able to track events within the brain with millisecond accuracy – and that it is in principle portable allowing real-world neuroimaging to be performed outside of clinical and lab environments. As a result it is a very widely used sensing modality for a range of health and wellbeing applications ranging from epilepsy diagnosis to emotionalmonitoring. The EEG is a very widely used technology for neuroimaging. It is unique amongst sensing methods in that it can monitor the brain portably, over a long period of time, and with a high time resolution for capturing rare and transient events. As a result it has seen substantial use in medical diagnoses and increasingly in out-of-the-lab brain monitoring.

PUFAs in the n-3 and n-6 (omega-3 and omega-6) families play a number of important physiological roles as components of cell membranes, as signaling mediators, and as precursors of signaling mediators. The role of PUFAs, particularly n-3 PUFAs, in brain development is well established. There is also increasing evidence that suboptimal levels of n-3 PUFAs, as a result of inadequate diet or metabolic deficiencies, appear to interact with genetic and environmental factors in the etiologies of a variety of neuropsychiatric disorders.PUFAs are important dietary fats containing more than one double bond, and are named according to the number of carbons they contain, the number of double bonds, and the position of the first double bond from the methyl end.
