Myelination of the central nervous system requires the generation of functionally mature oligodendrocytes from oligodendrocyte precursor cells (OPCs). Electrically active neurons may influence OPC function and selectively instruct myelination of an active neural circuit. In this work, we use optogenetic stimulation of the premotor cortex in awake, behaving mice to demonstrate that neuronal activity elicits a mitogenic response of neural progenitor cells and OPCs, promotes oligodendrogenesis, and increases myelination within the deep layers of the premotor cortex and subcortical white matter. We further show that this neuronal activity-regulated oligodendrogenesis and myelination is associated with improved motor function of the corresponding limb. Oligodendrogenesis and myelination appear necessary for the observed functional improvement, as epigenetic blockade of oligodendrocyte differentiation and myelin changes prevents the activity-regulated behavioral improvement.

Neuronal activity promotes oligodendrogenesis and adaptive myelination in the mammalian brain.

Medical student mistreatment remains a concern, particularly in the surgery clerkship. This is a single academic institution's report of medical student perceptions of a mistreatment program embedded in the surgery clerkship.

Medical student perceptions of a mistreatment program during the surgery clerkship.

Early exposure to surgery in a positive learning environment can contribute to increased student interest. The primary objectives of this study included developing increased comfort in the operating room (OR) environment, confidence in surgical skills, and mentorship for students interested in surgery.

Introductory Surgical Skills Course: Technical Training and Preparation for the Surgical Environment.

To examine the validity evidence for a scrub training knowledge assessment tool to demonstrate the utility and robustness of a multimodal, entrustable professional activity (EPA)-aligned, mastery learning scrub training curriculum.

Validity Evidence for a Knowledge Assessment Tool for a Mastery Learning Scrub Training Curriculum.

Many medical students mentally commit to specialties prior to entering clerkships. This is why early preclinical interactions with surgical specialties, through mentorship and/or interest groups, increases the opportunity to nurture enthusiasm for surgery. In 2007, a course providing preclinical medical students with introductory surgical skills training and preparation for the surgical environment ("SURG205") was established at our institution. The course underwent a major revision in 2016, increasing intraoperative mentorship by matching students to surgical attendings and requiring students to scrub into operative cases together. We anticipate that the positive surgical experiences created by the course will lead to further development and enhancement of student interest in surgical specialties-interest that we hypothesized would reflect in their National Resident Matching Program (NRMP) Match outcomes.

Preclinical Surgical Preparatory Course and the NRMP Match: Early Exposure and Surgical Recruitment a 10-Year Follow-Up.

Recent endeavors from governing bodies such as the AAMC have formally recognized the importance of aseptic technique. AAMC guidelines include activities that all graduating physicians should be able to perform with minimum indirect supervision and were developed to recognize these needs. For example, the skills necessary for aseptic technique include daily safety habits and general physician procedures.
