Dual-Factor Representation of the Environmental Context in the Retrosplenial Cortex.

The retrosplenial cortex (RSC) is thought to be involved in a variety of spatial and contextual memory processes. However, we do not know how contextual information might be encoded in the RSC or whether the RSC representations may be distinct from context representations seen in other brain regions such as the hippocampus. We recorded RSC neuronal responses while rats explored different environments and discovered 2 kinds of context representations: one involving a novel rate code in which neurons reliably fire at a higher rate in the preferred context regardless of spatial location, and a second involving context-dependent spatial firing patterns similar to those seen in the hippocampus.

Emergency Physicians' Perceived Influence of EHR Use on Clinical Workflow and Performance Metrics.

Objective: Over the last decade, electronic health records (EHRs) have shaped clinical practice. In this article, we investigated the perceived effects of EHR use on clinical workflow and meaningful use (MU) performance metrics.

Materials And Methods: Semistructured interviews were conducted with 20 (= 20) physicians at two urban emergency departments.
