Background: Peripheral nerve stimulation (PNS) has emerged as a minimally invasive percutaneous procedure addressing neuropathic pain. However, the percutaneous cylindrical lead ultrasound-guided implantation procedure requires expertise that limits widespread PNS utilization. To overcome these challenges, a microinvasive endoscopy device has very recently been developed, enhancing the precision of PNS implantation by providing accurate visualization of the targeted nerve.

- Understanding the deep brain's architecture is difficult due to its complex structure, which controls movement and behavior, and lacks dedicated exploration tools.
- A new deep-brain MRI architecture atlas was created using advanced MRI-based mapping techniques, featuring a young male adult template and various MRI datasets.
- This open-source tool includes high-resolution images of 118 labeled deep brain structures, enhancing existing 3D atlases and clinical resources for better analysis.
Objective: To identify optimal bipolar stimulation parameters for robust generation of brain evoked potentials (BEPs), namely the interelectrode distance (IED) and the intensity of stimulation (IS), in cortical and axonal stimulation.
Methods: In 15 patients who underwent awake surgery for brain tumor removal, BEPs were elicited at different values of IED and IS, respectively: 5 mm-5 mA, 5 mm-10 mA, and 10 mm-10 mA. The number of BEPs elicited by stimulation, as well as the delays and amplitudes of the N1 waves were compared between the different groups of stimulation parameters and according to the stimulated brain structure (cortical vs.
Objective: The sensory ventroposterior (VP) thalamic nuclei display a mediolateral somatotopic organization (respectively head, arm, and leg). We studied this somatotopy using directional VP deep brain stimulation (DBS) in patients treated for chronic neuropathic pain.
Methods: Six patients with central (four) or peripheral (two) neuropathic pain were treated by VP DBS using directional leads in a prospective study (clinicaltrials.
