Whole brain optical imaging

Nowadays, there are several imaging techniques offering a complementary approach to visualize intact neural networks on large areas. Each of those offers a different strategy and furnish complementary information on the role of neural components. We will describe different approaches enabling to move from single neuron details to whole brain imaging, connecting short range structural information to long range one. In particular, some examples of correlative microscopies, combining linear and non linear techniques will also be described.
