Cortical spreading depolarization (CSD), cortical spreading ischemia (CSI), and early brain injury are involved in the occurrence of delayed brain ischemia after subarachnoid hemorrhage (SAH). We tested whether local application of magnesium (Mg) sulfate solution suppressed CSD and CSI, and decreased brain damage in a rat SAH-mimicking model. ⋯ Local application of Mg suppressed CSI and reduced brain damage in a rat SAH-mimicking model. Mg irrigation therapy may be beneficial to suppress brain damage due to CSI after SAH.

We examined performance differences between expert and novice neurosurgeons under a surgical microscope with the goal to evaluate surgical expertise. ⋯ The action-related fixation can be used to evaluate microsurgeons' level of expertise and in surgical education for gaze training.
