Combined Near-infrared Fluorescent Imaging and Micro-computed Tomography for Directly Visualizing Cerebral Thromboemboli

This protocol describes the application of combined near-infrared fluorescent (NIRF) imaging and micro-computed tomography (microCT) for visualizing cerebral thromboemboli. This technique allows the quantification of thrombus burden and evolution. The NIRF imaging technique visualizes fluorescently labeled thrombus in excised brain, while the microCT technique visualizes thrombus inside living animals using...

Language: The N400 in Semantic Incongruity

Source: Laboratories of Sarah I. Gimbel and Jonas T. Kaplan— University of Southern California
Understanding language is one of the most complex cognitive tasks that humans are capable of. Given the incredible amount of possible choices when combining individual words to form meaning in sentences, it is crucial that the brain is able to identify when words form coherent combinations and when an anomaly appears that undermines meaning. Extensive research has shown that certain...

Interaction between Phonological and Semantic Processes in Visual Word Recognition using Electrophysiology

We present a protocol to explore the relative activation sequence of phonology and semantics in visual word recognition. The results show that consistent with interactive accounts, semantic and phonological representations may be processed interactively, and higher-level linguistic representations may affect early...

Visualization of Mouse Cerebral Thrombi Using Near-Infrared Fluorescence Imaging

Source: Kim, D. E., et al. Combined Near-infrared Fluorescent Imaging and Micro-computed Tomography for Directly Visualizing Cerebral Thromboemboli. J. Vis. Exp. (2016)This video demonstrates near-infrared fluorescent (NIRF) imaging to visualize thrombi in excised brain tissue labeled with a fibrin-specific probe. Near-infrared light excites the probe, causing the thrombus to fluoresce, enabling high-contrast thrombi visualization in the major cerebral artery and small cortical blood...

Enhancing Electrode Location Assessment in Cochlear Implantation via Computed Tomography Image Fusion

This protocol demonstrates a method for fusing pre-operative and post-operative computed tomography images for cochlear implant recipients. The approach may enhance the measurement accuracy of insertion depth and the center frequency of electrode array contacts. Additionally, this method has potential applications in anatomy-based fitting, an emerging area within the cochlear implant...
