This work demonstrates the compatibility of a newly developed glass-guided microelectrode design and microfeed equipment with high-resolution 3D magnetic resonance imaging (MRI). T1- and T2-weighted images allow for the non-invasive visualization of chronically implanted microelectrodes within the brain stem of squirrel monkeys in vivo. Neural extracellular multi-unit recordings proved the functionality of the microelectrode before and after the use of 3D MRI suggesting the preservation of normal brain tissue at the tip of the electrode. Because histology confirmed the absence of lesions attributable to MRI, the approach offers an interactive monitoring during the course of neuroethological experiments. Consequently, MRI may become an in vivo alternative to common histological post mortem verifications of electrode tracks and hence may avoid the early sacrificing of primates after only a small number of experiments."],["dc.identifier.doi","10.1016/j.jneumeth.2005.10.018"],["dc.identifier.gro","3150378"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/7136"],["dc.language.iso","en"],["dc.notes.status","zu prüfen"],["dc.relation.issn","0165-0270"],["dc.title","Compatibility of glass-guided recording microelectrodes in the brain stem of squirrel monkeys with high-resolution 3D MRI"],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dc.type.peerReviewed","yes"],["dspace.entity.type","Publication"]]

A STEAM sequence with image acquisition times of about 500 ms was implemented at 2.35 T using six gradient orientations and b values of 200, 700, and 1200 s mm(-2). The use of half Fourier phase-encoding increased the signal-to-noise ratio by 45% relative to full Fourier acquisitions. Moreover, STEAM-derived maps of the relative anisotropy and main diffusion direction were completely free of susceptibility-induced signal losses and geometric distortions. Within measuring times of 3 h, the achieved resolution varied from 600x700x1000 microm3 for squirrel monkeys to 140x280x720 microm3 for mice. While in monkeys the accessible white matter fiber connections were comparable to those reported for humans, detectable fiber structures in mice focused on the corpus callosum, anterior commissure, and hippocampal fimbria. In conclusion diffusion-weighted single-shot STEAM MRI allows for in vivo diffusion tensor mapping of the brain of squirrel monkeys, rats, and mice without motion artifacts and susceptibility distortions."],["dc.identifier.doi","10.1007/s10334-004-0069-1"],["dc.identifier.gro","3150383"],["dc.identifier.pmid","15580374"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/7141"],["dc.language.iso","en"],["dc.notes.status","final"],["dc.relation.issn","0968-5243"],["dc.subject","Magnetic resonance imaging; Diffusion-weighted imaging; Anisotropy; White matter; Animal brain"],["dc.title","In vivo diffusion tensor mapping of the brain of squirrel monkey, rat, and mouse using single-shot STEAM MRI"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","no"],["dspace.entity.type","Publication"]]
