A novel method to trigger the reconsolidation of fear memory.

The procedure of memory reconsolidation provides an opportunity to improve some mental disorders caused by maladaptive memories, such as Posttraumatic Stress Disorder. Prediction error was considered a necessary condition for triggering memory reconsolidation. However, it is difficult to create a satisfying prediction error to successfully open memory reconsolidation in a clinical context. The purpose of this study was to explore a more practicable method to trigger memory reconsolidation. We used a success...

The Influence of Phonomotor Treatment on Word Retrieval: Insights From Naming Errors.

Purpose An increasing number of anomia treatment studies have coupled traditional word retrieval accuracy outcome measures with more fine-grained analysis of word retrieval errors to allow for more comprehensive measurement of treatment-induced changes in word retrieval. The aim of this study was to examine changes in picture naming errors after phonomotor treatment. Method Twenty-eight individuals with aphasia received 60 hr of phonomotor treatment, an intensive, phoneme-based therapy for anomia. Confronta...

Direct and generative autobiographical memory retrieval: How different are they?

Theories of autobiographical memory have emphasised effortful generative retrieval, but recent research indicates that subjectively effortless direct retrieval is common. We compared the processes of direct and generative retrieval. Sixty-five participants retrieved 24 autobiographical memories across three cue types: concrete, emotional, and personal. We recorded retrieval latency, and participants judged direct versus generative retrieval and rated memory specificity, vividness, significance, rehearsal, a...

Direct Error-Driven Learning for Deep Neural Networks With Applications to Big Data.

In this brief, heterogeneity and noise in big data are shown to increase the generalization error for a traditional learning regime utilized for deep neural networks (deep NNs). To reduce this error, while overcoming the issue of vanishing gradients, a direct error-driven learning (EDL) scheme is proposed. First, to reduce the impact of heterogeneity and data noise, the concept of a neighborhood is introduced. Using this neighborhood, an approximation of generalization error is obtained and an overall error...

Retrieval practice decreases processing load of recall: Evidence revealed by pupillometry.

Retrieval practice is an effective long-term learning strategy. Items practiced through repeated retrieval are resistant to interference, stress, and secondary load, which attributes also characterize automatization in skill learning. In two experiments, we investigated whether retrieval practice is associated with decrease in processing load, which is a further attribute of automatization. Participants first learned paired associates, and then they practiced the items either by repeatedly studying or engag...

On the sensitivity of event-related potentials to retrieval mode.

Event-related potential (ERP) signatures of preparation to retrieve episodic memories have been identified in several studies. A common finding is relatively more positive-going ERP activity over right-frontal sites when people prepare for episodic rather than semantic retrieval. This activity has been linked to the process of retrieval mode - a retrieval set that ensures subsequent events are treated as cues for episodic retrieval. This experiment was designed to test one explanation for why this putative ...

Intravenous Vancomycin Therapeutic Drug Monitoring in Children: Evaluation of a Pharmacy-Driven Protocol and Collaborative Practice Agreement.

Vancomycin optimization is challenging, requiring careful therapeutic drug monitoring (TDM) to avoid toxicity and ensure an efficacious concentration. Most prescriptions are empiric and often discontinued within 72 hours, which makes early TDM unnecessary. Although TDM using trough levels is common, the area under the concentration-time curve (AUC) is the preferred pharmacodynamic target. We studied the effect of a pharmacy-driven vancomycin collaborative practice agreement (CPA) at a children's hospital th...

Dynamic internal states shape memory retrieval.

Why do we sometimes easily retrieve memories, but other times appear to forget them? We often look to our external environment for retrieval cues, but another way to optimize memory retrieval is to be in a mental state, or mode, that prioritizes access to our internal representation of the world. Such a 'retrieval mode' was proposed by Endel Tulving (1983), who considered it a neurocognitive state in which one keeps the goal of memory retrieval in mind. Building on Tulving's proposal, we review converging e...

Failed sperm retrieval from severely oligospermic or non-obstructive azoospermic patients on oocyte retrieval day: Emergent oocyte cryopreservation is a feasible strategy.

Unexpected sperm retrieval failure on the day of oocyte retrieval is not common but frequently happened in patients with severe oligospermia or non-obstructive azoospermia(NOA). Oocyte cryopreservation is a common strategy after failed collection of sperm when concurrent ovarian stimulation is underwent. However, the use of oocyte vitrification in such male-infertility cases remains unclear.

Safety and efficacy of leadless pacemaker retrieval.

The success rate of leadless cardiac pacemaker retrieval remains a major concern for this disruptive technology. The present paper performed a systematic review of the safety and feasibility of the retrieval of leadless cardiac pacemakers.

Adolescent nonsuicidal self-injury and cortisol response to the retrieval of adversity: A sibling study.

There is evidence for alterations in hypothalamus-pituitary-adrenal (HPA) axis response to the retrieval of traumatic events among individuals with Posttraumatic Stress Disorder. However, no study has so far investigated HPA response to trauma retrieval among individuals engaging in non-suicidal self-injury (NSSI). In the present study, we compared reports of childhood adversity (CA) between adolescents engaging in NSSI and their siblings and tested for differences in the cortisol response to the retrieval ...

A gist orientation before retrieval impacts the objective content but not the subjective experience of episodic memory.

A gist retrieval-orientation decreases one's ability to remember objective details from past experiences. Here, we examined whether a gist retrieval-orientation manipulation can impact both the objective and subjective aspects of remembering. Young participants took part in two cued-recollection tasks in which they studied pictures associated with labels; at retrieval, from the labels, they evaluated the vividness of their memories of the corresponding pictures, and recalled picture details. Before retrieva...

Neural correlates underlying the effect of reward value on recognition memory.

The prioritized encoding and retrieval of valuable information is an essential aspect of human memory. We used electroencephalography (EEG) to determine which of two hypothesized processes underlies the influence of reward value on episodic memory. One hypothesis is that value engages prefrontal executive control processes, so that valuable stimuli engage an elaborative rehearsal strategy that benefits memory. A second hypothesis is that value acts through the reward-related midbrain dopamine system to modu...

Structural Properties and Magnetic Ordering in 2D Polymer Nanocomposites: Existence of Long Magnetic Dipolar Chains in Zero Field.

The existence of magnetic dipolar nanoparticle chains at zero field has been predicted theoretically for decades, but these structures are rarely observed experimentally. A prerequisite is a permanent magnetic moment on the particles forming the chain. Here we report on the observation of magnetic dipolar chains of spherical iron oxide nanoparticles with a diameter of 12.8 nm. The nanoparticles are embedded in an ultrathin polymer film. Due to the high viscosity of the polymer matrix, the dominating aggre...

Iterative Retrieval and Block Coding in Autoassociative and Heteroassociative Memory.

Neural associative memories (NAM) are perceptron-like single-layer networks with fast synaptic learning typically storing discrete associations between pairs of neural activity patterns. Gripon and Berrou (2011) investigated NAM employing block coding, a particular sparse coding method, and reported a significant increase in storage capacity. Here we verify and extend their results for both heteroassociative and recurrent autoassociative networks. For this we provide a new analysis of iterative retrieval in...

How to evaluate agreement between quantitative measurements.

When a method comparison study is performed, the aim is to evaluate the agreement of measurements of different methods. We present the Bland-Altman plot with limits of agreement as the correct analysis methodology. We also discuss other scaled and unscaled indices of agreement and commonly used inappropriate approaches.

Spacing and Mate Attraction: Sex-Specific Function of Advertisement Calls in the Northern Giant Mouse Lemur (Mirza zaza).

It has been proposed that primates use advertisement calls exclusively to negotiate spacing, but the function of female calls has rarely been studied. Here, we investigated the function of male and female advertisement calls in the northern giant mouse lemur (Mirza zaza),a non-gregarious nocturnal primate from north-western Madagascar. We recorded advertisement calls and associated behaviours of 35 M. zaza individuals at the Duke University Lemur Center. We found that females of M. zazaexclusively use their...

Attraction Between Like-Charged Macroions Mediated by Specific Counter-Ion Configurations.

Attraction between like-charged macroions is fundamental to many processes in biology, chemistry and physics. It also plays an important role in industrial applications such as ion extraction processes or catalysis. In this work we report a novel mechanism by which attraction can be realized between spherical macroions at high ionic strength. It consists of specific configurations of two, three and more counterions that appear between macroins with high statistical probability. The attraction is manifested ...

A survey of outpatient Internal Medicine clinician perceptions of diagnostic error.

Background Little is known about how practicing Internal Medicine (IM) clinicians perceive diagnostic error, and whether perceptions are in agreement with the published literature. Methods A 16-question survey was administered across two IM practices: one a referral practice providing care for patients traveling for a second opinion and the other a traditional community-based primary care practice. Our aim was to identify individual- and system-level factors contributing to diagnostic error (primary outcome...

The effect of rule retrieval on activity in the default mode network.

The default mode network (DMN) is often associated with internally-directed cognition, distinct from the constraints of the external environment. However, a recent finding is that the DMN shows strong activation after large task switches during a demanding externally-directed task (Crittenden et al., 2015; Smith et al., 2018). Following other proposals, we have suggested that the DMN encodes cognitive or environmental context, and that context representations are momentarily strengthened during large cognit...

Permanent His Bundle Pacing using Stylet Directed, Active Fixation Leads Placed via Coronary Sinus Sheaths as Compared to Conventional Lumen-less System.

The use of coronary sinus sheaths to deliver stylet-driven leads for His bundle pacing (HBP) has not been described. Conventionally, HBP is achieved using a styletless lead delivered through a customized catheter.

Associations between memory and verbal fluency tasks.

Previous studies have provided inconsistent evidence concerning the association between delayed retrieval of story information from long-term memory and retrieval of words on verbal fluency tasks. The current study looks for shared retrieval mechanisms in these tasks from childhood to old age. Three-hundred and eighty participants (ages 5-91) performed tasks of story recall, digit span, phonemic fluency, and semantic fluency. Significant correlations between delayed story recall and both fluency tasks emerg...

Harmonized Multimodal Learning with Gaussian Process Latent Variable Models.

Multimodal learning aims to discover the relationship between multiple modalities. It has become an important research topic due to extensive multimodal applications such as cross-modal retrieval. This paper attempts to address the modality heterogeneity problem based on Gaussian process latent variable models (GPLVMs) to represent multimodal data in a common space. Previous multimodal GPLVM extensions generally adopt individual learning schemes on latent representations and kernel hyperparameters, which ig...
