Cognitive impairment resulting from the radiotherapeutic management of brain tumors represents a clinically intractable condition that adversely impacts quality of life. The capability to critically evaluate potential interventions for ameliorating radiation-induced cognitive decrements ultimately depends on the capability to undertake rigorous quantitative assessments of cognition.

The cranial mesenchyme undergoes dramatic morphogenic movements that likely provides a driving force for elevation of the neural folds1,2. Here we describe a simple ex vivo explant assay to characterize the cellular behaviors of the cranial mesenchyme during neurulation. This assay has numerous applications including being amenable to pharmacological manipulations and live imaging analyses.

MazeSuite is a complete toolset to prepare, present and analyze navigational and spatial experiments. Functional near-infrared spectroscopy (fNIR) is an optical brain imaging technique that enables noninvasive and portable monitoring of cerebral blood oxygenation changes. This paper summarizes collective use of MazeSuite and fNIR within a cognitive processing learning paradigm.
FAQs
Registration aligns the patient’s actual anatomy with corresponding MRI or CT data. This step establishes a shared spatial reference, allowing the system to relate an instrument’s observed position to structures represented in the images. The accuracy of that image-to-patient relationship is important because subsequent guidance depends on how reliably the displayed anatomy corresponds to the patient during the procedure.
Optical and electromagnetic trackers provide alternative ways to monitor instrument position during an operation. Regardless of the tracking modality, the system uses this position information to show where the instrument lies relative to image-based brain anatomy. This connection helps the surgical team maintain orientation while working toward a planned target, including deep or functionally important regions.
Cranial navigation is especially valuable when the intended path or target is difficult to judge from exposed anatomy alone. Relating the instrument to preoperative or intraoperative images can support decisions near deep structures or areas with important function. The technology therefore adds image-based orientation to clinical judgment rather than serving as an independent substitute for surgical expertise.
A typical workflow begins with acquisition of MRI or CT data, followed by registration of those images to the patient before or during surgery. The tracking system then monitors the selected instrument, and the display presents its position within the registered anatomy. This sequence links preoperative or intraoperative imaging with surgical planning, targeting, and anatomical orientation.
Different procedures require different targeting goals. During tumor resection, navigation can help relate the operative approach to the imaged lesion; during biopsy, it can support access to a selected target; and during electrode placement, it can assist positioning relative to brain anatomy. These applications show how one guidance platform can support both tissue removal and focused placement tasks.
In neuroscience, cranial navigation connects surgical actions with three-dimensional brain structure and functionally important regions. Image-based localization can make anatomical relationships more explicit during planning and targeting, particularly when deep structures are involved. It supports precise decision-making while interpretation of the anatomy and final operative choices remain responsibilities of the clinical team.
