Live-feed use in the classroom as an engagement tool.

Background And Purpose: Recent studies suggest that social media use in the classroom leads to improved engagement and participation. However, student attitudes regarding classroom engagement, academic performance, and overall teaching effectiveness toward this tool have been mixed. The aim of this study was to determine the effectiveness of live-feed on students' classroom engagement.

The impact of a diagnostic reminder system on student clinical reasoning during simulated case studies.

Introduction: Diagnostic reminder systems (DRS) may help students improve their clinical reasoning skill and gain competency in using informatics tools. This study explored the influence of Isabel PRO, a web-based DRS, on student diagnostic reasoning during simulated encounters.

Methods: Diagnostic reasoning was assessed in 20 fourth-year medical students during four simulated case scenarios.

Noradrenergic antagonism of the P13 and N40 components of the rat auditory evoked potential.

Rationale: Two rat auditory evoked potential (AEP) components P13 and N40 are suggested as analogues to the human P50, which has abnormal suppression properties in schizophrenia. However, P50 likely reflects neural activity from several different brain areas. Studies examining each of these components in the rat model have proposed circuitry that involves alpha2 norepinephrine (NE) receptors, and different disruption effects are predicted depending on whether effects are presynaptic or postsynaptic.

GABA(B) receptor gene expression is not altered in cocaine-sensitized rats.

Recent behavioral and neurobiological data indicate that GABA(B) receptor transmission is involved in cocaine-induced hyperactivity and reinforcement. GABA(B) receptor gene expression in cocaine-sensitized rats was examined in this study. Rats were injected with cocaine (15 mg/kg, daily, i.
