dc.description.abstract | Neural circuits, groups of neurons connected in directional manner, play a central role in information processing. Advances in neuronal biology research is limited by a lack of appropriate in vitro methods to construct and probe neuronal networks. Here, we describe a microfluidic culture platform that directs the growth of axons using "neural diode" structures to control neural connectivity. This platform is compatible with live cell imaging and can be used to (i) form pre-synaptic and postsynaptic neurons by directional axon growth and (ii) localize physical and chemical treatment to pre-or postsynaptic neuron groups (i.e. virus infection and etc.). The "neural diode" design consist of a microchannel that split into two branches: one is directed straight toward while the other returns back toward the starting point in a closed loop to send the axons back to the origin. We optimized the "neural diode" pattern dimension and design to achieve close to 70% directionality with a single unit of the "diode". When repeated 3 times, near perfect (98-100% at wide range of cell concentrations) directionality can be achieved. The living neural circuit was characterized using Ca imaging and confirmed their function. The platform also serves as a straightforward, reproducible method to recapitulate a variety of neural circuit in vitro that were previously observable only in brain slice or in vivo models. The microfluidic neural diode may lead to better models for understanding the neural circuit and neurodegenerative diseases. | - |
