Enhancing Primary Care Learning in a Referral Hospital Setting: Introducing Veterinary Clinical Demonstrators.

With the majority of veterinary graduates entering primary care practice (PCP), there is increasing recognition of the importance of preparing students to practice across a broad spectrum of care (SoC). The traditional model of veterinary training, focused on the referral hospital environment, can make this challenging. In 2018, Bristol Veterinary School recruited five primary care (PC) veterinary surgeons as veterinary clinical demonstrators (VCDs) who collaborated with rotation-specific specialists to help enhance student focus upon day-one skills and to emphasize SoC relevance of the referral caseload.

Two kinds of memory signals in neurons of the human hippocampus.

Prior studies of the neural representation of episodic memory in the human hippocampus have identified generic memory signals representing the categorical status of test items (novel vs. repeated), whereas other studies have identified item specific memory signals representing individual test items. Here, we report that both kinds of memory signals can be detected in hippocampal neurons in the same experiment.

One-trial perceptual learning in the absence of conscious remembering and independent of the medial temporal lobe.

A degraded, black-and-white image of an object, which appears meaningless on first presentation, is easily identified after a single exposure to the original, intact image. This striking example of perceptual learning reflects a rapid (one-trial) change in performance, but the kind of learning that is involved is not known. We asked whether this learning depends on conscious (hippocampus-dependent) memory for the images that have been presented or on an unconscious (hippocampus-independent) change in the perception of images, independently of the ability to remember them.

Neuropsychological and neuropathological observations of a long-studied case of memory impairment.

We report neuropsychological and neuropathological findings for a patient (A.B.), who developed memory impairment after a cardiac arrest at age 39.

Spiking activity in the human hippocampus prior to encoding predicts subsequent memory.

Encoding activity in the medial temporal lobe, presumably evoked by the presentation of stimuli (postonset activity), is known to predict subsequent memory. However, several independent lines of research suggest that preonset activity also affects subsequent memory. We investigated the role of preonset and postonset single-unit and multiunit activity recorded from epilepsy patients as they completed a continuous recognition task.
