Psychometric Testing of a Simulation Rubric for Measuring Interprofessional Communication.

Aim: The aim of this study was to establish psychometric testing of the Indiana University Simulation Integration Rubric (IUSIR), a tool for measuring interprofessional communication in simulations.

Background: Educators engage in a wide variety of activities to promote interprofessional education, with many of these activities involving simulation. As interprofessional education evolves, tools are needed to measure the effectiveness of interventions.

The blood supply of the cat's visual cortex and its postnatal development.

We examined the blood supply of the cat's visual cortex using alkaline phosphatase histochemistry to demonstrate the capillary endothelial cells. In the adult, layer 4 is marked by a band that is of obviously greater density, extends throughout areas 17 and 18, and ends abruptly at the 18/19 border. We quantified blood vessel density in area 17, observing a 23% greater density in layer 4 than in supragranular and infragranular layers.

Intracellular injection in fixed slices: obtaining complete dendritic arbors of large cells.

Intracellular injection of Lucifer yellow into fixed brain slices is widely used to demonstrate dendritic morphology. A major limitation of this technique is that large dendritic arbors are usually truncated at the cut surfaces. Here we describe modifications that allowed us to obtain complete dendritic arbors of large spiny stellate cells.
