From: Burst predicting neurons survive an in vitro glutamate injury model of cerebral ischemia

Excitotoxic insult causes widespread neuronal death.
(a) Two representative phase contrasts (top row) as well as propidium iodide (PI) and fluorescent images (bottom row). PI images have inversed colour tones. (b) Percentage of dead neurons for each treatment condition (see Assessment of Neuronal Injury section). Error bars are standard error of the mean.
