There is the usual, gradual accretion of understanding of the details of particular circuits in both inver-Neurons, Networks, and Motor Behavior tebrates and vertebrates. Although such accounts are essential as the foundation for extracting principles of Edited motor control, the more important advances are those which change the way we think about circuits generally. These have occurred on several fronts and have in common the development of a much better appreciation for the dynamic aspects of motor circuits. The most fundamental change in our thinking is one that is clearly owed to the invertebrate models. This is Even though studies of neuronal networks for movement do not move at the blistering speed of molecular biology, the notion that circuits, as defined by anatomical connections , can be reconfigured in very dynamic ways to important advances still occur at a steady pace. This produce different motor outputs.

The book emphasizes those systems in which motor circuits are reasonably well defined at a cellular level, including the brainstem and spinal cord of vertebrates and key model systems from invertebrates.

Evaluation in France: a Decade of Experience
In France, the last decade has been marked by the institutionalisation of evaluation as part of the landscape of public policies. This movement started with science and technology, which, compared to other public policies, went through a specific institutionalisation process. In this chapter I shall present the main transformations and draw some preliminary conclusions on the specific choice ma...
