This systematic protocol describes a new animal model of post-traumatic epilepsy after repetitive mild traumatic brain injury. The first part details steps for traumatic brain injury induction using a modified weight drop model. The second part provides instructions on the surgical approach for single- and multi-channel electroencephalographic data acquisition systems.

We present a method for replicating the glioma tumor microenvironment at the invasive front that incorporates interstitial fluid flow. This model is a hyaluronan-collagen I hydrogel in a tissue culture insert where a fluid pressure head can be applied. Invasion can be quantified, and cells can be isolated or lysed.
