The Superficial Anastomosing Veins of the Human Brain Cortex: A Microneurosurgical Anatomical Study.

In this microneurosurgical and anatomical study, we characterized the superficial anastomosing veins of the human brain cortex in human specimens. We used 21 brain preparations fixed in formalin (5%) that showed no pathological changes and came from the autopsy sections. The superficial veins were dissected out of the arachnoid with the aid of a surgical microscope.

Restoration of ankle movements with the ActiGait implantable drop foot stimulator: a safe and reliable treatment option for permanent central leg palsy.

OBJECT The ActiGait drop foot stimulator is a promising technique for restoration of lost ankle function by an implantable hybrid stimulation system. It allows ankle dorsiflexion by active peroneal nerve stimulation during the swing phase of gait. In this paper the authors report the outcome of the first prospective study on a large number of patients with stroke-related drop foot.

Accuracy of subthalamic nucleus targeting by T2, FLAIR and SWI-3-Tesla MRI confirmed by microelectrode recordings.

Background: Successful deep brain stimulation is mostly dependent on accurate positioning of the leads at the optimal target points. We investigated whether the identification of the subthalamic nucleus in T2-weighted 3-T MRI, fluid-attenuated inversion recovery 3-T MRI and susceptibility-weighted 3-T MRI is confirmed by intraoperative neurological microelectrode recording.

Methods: We evaluated 182 microelectrode recording leads in 21 patients with bilateral deep brain stimulation, retrospectively.
