1. Mild in vitro trauma induces rapid Glur2 endocytosis, robustly augments calcium permeability and enhances susceptibility to secondary excitotoxic insult in cultured Purkinje cells by Joshua D.

2. Validation of Purkinje cell culture system via immunocytochemical labelling using glial fibrillary acidic protein (GFAP) (A), calbindin D-28K (B), MAP2 (C,D) as markers for astrocytes, Purkinje cells and neurons, respectively. Joshua D. Bell et al. Brain 2007;130:2528-2542 © 2007 The Author(s)‏

3. (A) Injury magnitude-propidium iodide (PI) uptake dose–response curve for stretch pressures ranging from 2.5 to 7.5 psi. Joshua D. Bell et al. Brain 2007;130:2528-2542 © 2007 The Author(s)‏

4. Mild stretch robustly augments AMPA induced calcium influx as evidenced by normalized Purkinje cell Fura-2AM ratios (340 nm/380 nm) following application of 4 µM AMPA. (A) Calcium influx is moderate, and quickly returns to baseline values in control cells. Joshua D. Bell et al. Brain 2007;130:2528-2542 © 2007 The Author(s)‏
