Intraoperative microelectrode recording equipment: what features are necessary?
Intraoperative neurophysiologic methods for localizing targets deep in the brain require the use of specialized monitoring and recording equipment, including stimulators, neurophysiologic recording devices, and image manipulation tools. When using microelectrode recording devices there are some specifications that are more important than others, such as signal-to-noise ratios and amplifier impedance. As more companies develop tools to be used in the operating room, the end users have more choices. Some of the more important specifications are discussed and a comparison is made of the five major brands on the market today.

Comparative StudySpinal cord stimulation prevents the effects of combined experimental ischemic and traumatic brain injury. An MR study.
Spinal cord stimulation (SCS) interferes with cerebral blood flow (CBF). In this paper we try to evaluate the possible preventing effect of SCS in an animal model of combined ischemic and traumatic injury. ⋯ MR examination was performed in all the animals at the end of the experiments. Compared to the control group none but one of the SCS showed lesional pattern far from the craniectomy suggesting a 'preventing' effect of SCS on the secondary damage associated with our model combined ischemic and traumatic brain injury.

Combined treatment with stereotactic intracavitary irradiation and gamma knife surgery for craniopharyngiomas.
To evaluate the effectiveness of the combined treatment of stereotactic intracavitary irradiation and Gamma Knife surgery on craniopharyngiomas. ⋯ Gamma Knife surgery plays an important role in the treatment of the solid component of craniopharyngiomas and the combination of treatment is a simple, safe and effective method for treatment of craniopharyngiomas, especially for the recurrent mixed solid and cystic tumors.
