We are broadly interested in the relationship between structural and functions in the brain, particularly at the level of micro-circuits. We often employ reduced experimental preparations such as dissociated neuron cell culture because they are a precious model to investigate electrical activity, synaptic transmission, and overall, the emergence of collective states. The method we propose is ideal for rapid fabrication of microscale, polymeric devices.

This can be immediately used for the experimental study of modular neural networks in a dish, and it do not requires a high level of technical expertise in soft photolithography. This method and our simple proof of concept allow the designing of modular neuronal networks where we can define the structure, and control the flow of biological signals. Drug screening and investigation of pathological conditions immediately benefit from these sophisticated in vitro neuronal networks.
