Methods During neuronavigated operations of 20 patients with supratentorial cerebral lesions, the amount of brain shift was measured using neuronavigation system.

方法大脑内病变20例，术中在硬脑膜打开前、后用导航仪测出硬脑膜和脑表面标记点的差值，为病变切除前的脑移位量。

Objective A quantitative analysis of intraoperative brain shift in neuronavigator-guided surgery was performed to evaluate the impact of brain shift on accuracy of neuronavigation.

目的定量研究不同神经导航手术中的脑移位，评价术中脑移位对神经导航手术定位准确性的影响。

OBJECTIVE: Neuronavigational devices have traditionally used preoperative imaging with limited possibilities for adjustment to brain shift and intraoperative manipulation of the surgical lesions.

目的：神经导航装置传统上用于大脑变化调整低可能性时术前成像和术中手术病灶的处理。

This shift in language prompts the brain to focus on solutions rather than obstacles.

And it helps them shift into the meeting context with less strain on their brain.

And so, throughout the day, the more you shift contexts and the more unrelated those contexts are, the harder your brain works to transfer, store, and flush information out of short-term memory.
