Models of cerebral blood flow and metabolism have been very successful in reproducing the shape and timing of the haemodynamic response to neural activ- ity. On the other hand, as these models are mechanical or phenomenological in nature, they do not allow for judging the efficiency of the underlying allocation of energy. Here, we describe a complementary approach, suggesting that optimality with respect to resource constraints contributes to the characteristics of the haemodynamic response.
