Brain Vasculature Color-Labeling Using the Triple-Injection Method in Cadaveric Heads: A Technical Note for Improved Teaching and Research in Neurovascular Anatomy.

Background: Color-labeling injections of cadaveric heads have revolutionized education and teaching of neurovascular anatomy. Silicone-based and latex-based coloring techniques are currently used, but limitations exist because of the viscosity of solutions used.

Objective: To describe a novel "triple-injection method" for cadaveric cranial vasculature and perform qualitative and semiquantitative evaluations of colored solution penetration into the vasculature.

An evaluation of outcomes following the replacement of traditional histology laboratories with self-study modules.

Changes in medical school curricula often require educators to develop teaching strategies that decrease contact hours while maintaining effective pedagogical methods. When faced with this challenge, faculty at the University of Cincinnati College of Medicine converted the majority of in-person histology laboratory sessions to self-study modules that utilize multiple audiovisual modalities and a virtual microscope platform. Outcomes related to this shift were investigated through performance on in-house examinations, results of the United States Medical Licensing Examination (USMLE ) Step 1 Examination, and student feedback.

Medical student retention of embryonic development: impact of the dimensions added by multimedia tutorials.

The purpose of this project was to develop Web-based learning modules that combine (1) animated 3D graphics; (2) 3D models that a student can manipulate independently; (3) passage of time in embryonic development; and (4) animated 2D graphics, including 2D cross-sections that represent different "slices" of the embryo, and animate in parallel. These elements were presented in two tutorials, one depicting embryonic folding and the other showing development of the nervous system after neural tube formation. The goal was to enhance the traditional teaching format-lecture combined with printed diagrams, text, and existing computer animations-with customized, guided, Web-based learning modules that surpassed existing resources.
