Abstract

Parylene neurocages are biocompatible and very robust, making them ideally suited for studying neural networks. We present a design and fabrication process for building parylene neurocages for in vitro studies of neural networks. The fabrication process, on either silicon or glass substrates, incorporates electrodes into the neurocages to allow for stimulation and recording of action potentials. The resulting neurocages have a long-term cell survival rate of ∼50% and have proven to be 99% effective in trapping neurons.
