Excerpt
To the Editor: In peripheral tissues glucose uptake is established as a measure of insulin sensitivity, whereas the majority of glucose fluxes into the brain are insulin independent. However, at the level of neurons within the brain, insulin has been shown to modulate cell cycle, neurotransmitter production and electrical activity, and when insulin action fails, alterations in neuronal survival, food intake, body weight and determination of life-span occur. Based on these findings, insulin resistance of the brain is proposed to contribute to the development of obesity [
