Neurological Sciences > 2019 > 40 > 7 > 1443-1451

Background and purpose The Aperio thrombectomy device (Aperio) is a stent retriever designed to achieve rapid and substantial flow restoration in acute ischemic stroke due to large-vessel occlusions (LVOs). We evaluated the safety and efficacy of the Aperio device and compared it with published data of established stent retrievers. Methods We retrospectively analyzed institutional data of consecutive...

European Radiology > 2018 > 28 > 12 > 4949-4958

Objectives The pathogenesis leading to poor functional outcome after aneurysmal subarachnoid haemorrhage (aSAH) is multifactorial and not fully understood. We evaluated a machine learning approach based on easily determinable clinical and CT perfusion (CTP) features in the course of patient admission to predict the functional outcome 6 months after ictus. Methods Out of 630 consecutive subarachnoid...

On the integrity of functional brain networks in schizophrenia, Parkinson's disease, and advanced age: Evidence from connectivity‐based single‐subject classification

Human Brain Mapping > 38 > 12 > 5845 - 5858

Previous whole‐brain functional connectivity studies achieved successful classifications of patients and healthy controls but only offered limited specificity as to affected brain systems. Here, we examined whether the connectivity patterns of functional systems affected in schizophrenia (SCZ), Parkinson's disease (PD), or normal aging equally translate into high classification accuracies for these...

The aim of this study was to evaluate the objective and subjective image quality of a novel computed tomography (CT) protocol with reduced radiation dose for body packing with 80 kVp and automated tube current modulation (ATCM) compared to a standard body packing CT protocol. 80 individuals who were examined between March 2012 and July 2015 in suspicion of ingested drug packets were retrospectively...

Functional Connectivity Differences of the Subthalamic Nucleus Related to Parkinson's Disease

Christian Mathys, Julian Caspers, Robert Langner, Martin Südmeyer, więcej

Human Brain Mapping > 37 > 3 > 1235 - 1253

A typical feature of Parkinson's disease (PD) is pathological activity in the subthalamic nucleus (STN). Here, we tested whether in patients with PD under dopaminergic treatment functional connectivity of the STN differs from healthy controls (HC) and whether some brain regions show (anti‐) correlations between functional connectivity with STN and motor symptoms. We used functional magnetic resonance...

Target sites for transcallosal fibers in human visual cortex – A combined diffusion and polarized light imaging study

Cortex > 2015 > 72 > C > 40-53

Transcallosal fibers of the visual system have preferential target sites within the occipital cortex of monkeys. These target sites coincide with vertical meridian representations of the visual field at borders of retinotopically defined visual areas. The existence of preferential target sites of transcallosal fibers in the human brain at the borders of early visual areas was claimed, but controversially...

Human Brain Mapping > 36 > 5 > 1951 - 1962

Over 90 percent of patients with Parkinson's disease experience speech‐motor impairment, namely, hypokinetic dysarthria characterized by reduced pitch and loudness. Resting‐state functional connectivity analysis of blood oxygen level‐dependent functional magnetic resonance imaging is a useful measure of intrinsic neural functioning. We utilized resting‐state functional connectivity modeling to analyze...

Receptor architecture of visual areas in the face and word-form recognition region of the posterior fusiform gyrus

Brain Structure and Function > 2015 > 220 > 1 > 205-219

Recently, two extrastriate visual areas on the posterior fusiform gyrus, areas FG1 and FG2, were identified based on cytoarchitectonical criteria (Caspers et al. in Brain Struct Funct 218:511–526, 2013a). They are located within the object-related ventral visual stream at the transition between early and higher-order (category-specific) visual areas. FG2 has a topographical position which is best...

Functional characterization and differential coactivation patterns of two cytoarchitectonic visual areas on the human posterior fusiform gyrus

Human Brain Mapping > 35 > 6 > 2754 - 2767

The ventral stream of the human extrastriate visual cortex shows a considerable functional heterogeneity from early visual processing (posterior) to higher, domain‐specific processing (anterior). The fusiform gyrus hosts several of those “high‐level” functional areas. We recently found a subdivision of the posterior fusiform gyrus on the microstructural level, that is, two distinct cytoarchitectonic...

A novel meta-analytic approach: Mining frequent co-activation patterns in neuroimaging databases

Julian Caspers, Karl Zilles, Christoph Beierle, Claudia Rottschy, więcej

NeuroImage > 2014 > 90 > Complete > 390-402

In recent years, coordinate-based meta-analyses have become a powerful and widely used tool to study co-activity across neuroimaging experiments, a development that was supported by the emergence of large-scale neuroimaging databases like BrainMap. However, the evaluation of co-activation patterns is constrained by the fact that previous coordinate-based meta-analysis techniques like Activation Likelihood...

The mid-fusiform sulcus: A landmark identifying both cytoarchitectonic and functional divisions of human ventral temporal cortex

Kevin S. Weiner, Golijeh Golarai, Julian Caspers, Miguel R. Chuapoco, więcej

NeuroImage > 2014 > 84 > Complete > 453-465

Human ventral temporal cortex (VTC) plays a pivotal role in high-level vision. An under-studied macroanatomical feature of VTC is the mid-fusiform sulcus (MFS), a shallow longitudinal sulcus separating the lateral and medial fusiform gyrus (FG). Here, we quantified the morphological features of the MFS in 69 subjects (ages 7–40), and investigated its relationship to both cytoarchitectonic and functional...

Introduction Dynamic perfusion computed tomography (PCT) has been established as a diagnostic instrument for the detection of vasospasm after subarachnoid hemorrhage (SAH). The purpose of this study was to assess the prognostic impact of PCT parameters after SAH on the long-term outcome of patients.

Cytoarchitectonical analysis and probabilistic mapping of two extrastriate areas of the human posterior fusiform gyrus

The human extrastriate visual cortex comprises numerous functionally defined areas, which are not identified in the widely used cytoarchitectonical map of Brodmann. The ventral part of the extrastriate cortex is particularly devoted to the identification of visual objects, faces and word forms. We analyzed the region immediately antero-lateral to hOc4v in serially sectioned (20 μm) and cell body-stained...

2012 25th IEEE International Symposium on Computer-Based Medical Systems (CBMS)

Large-scale neuroimaging databases provide a rich fundus of functional neuroimaging experiments exhibiting maximum activation coordinates for specific task conditions. Aiming to explore major neuronal networks of the human brain, we developed a meta-analytic pattern-mining approach which combines Gaussian mixture modeling with the Apriori algorithm to identify frequent activation patterns within these...
