Prefrontal Neurons Encode Actions and Outcomes in Conjunction with Spatial Location in Rats Performing a Dynamic Delayed Non-Match to Position Task

To respond adaptively to change organisms must utilize information about recent events and environmental context to select actions that are likely to produce favorable outcomes. We developed a dynamic delayed nonmatching to position task to study the influence of spatial context on event-related activity of medial prefrontal cortex neurons during reinforcement-guided decision-making. We found neurons with responses related to preparation, movement, lever press responses, reinforcement, and memory delays. Combined event-related and video tracking analyses revealed variability in spatial tuning of neurons with similar event-related activity. While all correlated neurons exhibited spatial tuning broadly consistent with relevant task events, for instance reinforcement-related activity concentrated in locations where reinforcement was delivered, some had elevated activity in more specific locations, for instance reinforcement-related activity in one of several locations where reinforcement was delivered. Timing analyses revealed a limited set of distinct response types with activity time-locked to critical behavioral events that represent the temporal organization of dDNMTP trials. Our results suggest that reinforcement-guided decision-making emerges from discrete populations of medial prefrontal neurons that encode information related to planned or ongoing movements and actions and anticipated or actual action-outcomes in conjunction with information about spatial context

Assessing Patients\u27 Perceptions of Clinician Communication: Acceptability of Brief Point-of-Care Surveys in Primary Care

BACKGROUND: Improving patient-centered (PC) communication is a priority in many healthcare organizations. Most PC communication metrics are distal to the care encounter and lack clear attribution, thereby reducing relevance for leaders and clinicians. OBJECTIVE: We assessed the acceptability of measuring PC communication at the point-of-care. DESIGN: A brief patient survey was conducted immediately post-primary care appointments at one Veterans Affairs Medical Center. Audit-feedback reports were created for clinicians and discussed in qualitative interviews. PARTICIPANTS: A total of 485 patients completed the survey. Thirteen interviews were conducted with clinicians and hospital leaders. MAIN MEASURE(S): Measures included collaboRATE (a 3-item tool measuring PC communication), a question about how well needs were met, and overall visit satisfaction. Data were analyzed using descriptive statistics to characterize the mean and distribution of collaboRATE scores and determine the proportion of patients giving clinicians a top score on each item. Associations among responses were examined. Interviews focused on the value of measuring PC communication and were analyzed using a framework approach. KEY RESULTS: The proportion of patients giving PC communication top scores ranged from 41 to 92% for 16 clinicians who had \u3e /= 25 completed surveys. Among patients who gave top scores for PC communication, the odds of reporting that needs were completely met were 10.8 times higher (p \u3c .001) and the odds of reporting being very satisfied with their care were 13.3 times higher (p \u3c .001) compared with patients who did not give top scores. Interviewees found clinician-specific feedback useful; concerns included prioritizing this data when other measures are used to evaluate clinicians\u27 performance. Difficulties improving PC communication given organizational structures were noted. Recommendations for interventions included peer-to-peer education and mentoring by top-scoring clinicians. CONCLUSIONS: Assessing provider communication at the point-of-care is acceptable and useful to clinicians. Challenges remain to properly incentivize and support the use of this data for improving PC communication

Ce compte rendu s'inscrit dans le cadre d'un projet de recherche ayant pour objectif une comparaison entre traduction automatique et traduction humaine. Un exemple de traduction (allemand-anglais) effectuée par un programme interactif est examiné et comparé à la traduction faite par des étudiants-traducteurs. Le texte choisi, un texte technico-commercial relativement simple, est d'un type réputé apte à la traduction automatique. Les difficultés les plus fréquentes rencontrées par la traduction automatique aux différents niveaux linguistiques sont commentées, et les aspects essentiels d'une traduction dont le traducteur humain peut tenir compte mais non la machine évoqués
