Analysis of Contemporary Violin Recordings of 19th Century Repertoire: Identifying Trends and Impacts.

The study of violin recordings as evidence of interpretation and performance approach has been quite extensive throughout recent decades. Findings such as the limited use of vibrato in early recordings, the relative stabilization of tempo and rhythm characteristic of mid-20th century violin playing, or the effect of 'historically informed performance' (HIP) on 'mainstream' (MS) violinists performing early music repertoire, are fundamental in the identification of prevailing norms of practice and changes of ...

Differences in violin fixation force and muscle activity among violinists with and without complaints of the neck shoulder region.

The aim of this study is to determine the relationship between complaints of the neck and shoulder region, the jaw-shoulder violin fixation force, and the activity of the neck and shoulder muscles in violinists.

Memory: Theta Rhythm Couples Periodic Reactivation during Memory Retrieval.

Memory retrieval involves the reactivation of memory traces distributed throughout the brain. New research suggests that these memory reactivations have an oscillatory nature and that they are coupled to preferential stages of the hippocampal theta cycle.

Opinion: Virtual memory CD8 T cells and lymphopenia-induced memory CD8 T cells represent a single subset: homeostatic memory T cells.

It is well established that lymphopenia induces the formation of the memory-phenotype T cells without the exposure to foreign antigens. More recently, the memory-phenotype antigen-inexperienced memory T cells were described in lymphoreplete mice and called virtual memory T cells. In this review, we compare multiple aspects of the biology of lymphopenia-induced memory T cells and virtual memory T cells, including cytokine requirements, the role of T-cell receptor specificity in the differentiation process, g...

Memory bias and its association with memory function in women with posttraumatic stress disorder.

Memory abnormalities are among a central feature of posttraumatic stress disorder (PTSD). It is suggested that individuals with PTSD exhibit memory bias; while evidence shows poor memory function in these individuals. We aimed to examine memory bias in PTSD patients relative to controls and to explore an association between memory bias and memory function.

A trait for a high emotionality favors spatial memory to the detriment of cue-based memory in Japanese quail.

Recent studies provided evidence that a personality trait such as a trait for a high or a low emotionality can either promotes or impairs learning and memory performances. This variability can be partly explained because this trait may have opposite effect on memory performances depending on the memory system involved. The present study investigated in Japanese quail the relationships between emotionality and two forms of memory, spatial- memory and cue-based memory. We showed that birds with a high emotion...

Impact of stress response systems on forced choice recognition in an experimental trauma film paradigm.

Traumatic events are often followed by memory impairments of key features of the trauma. Stress hormones are involved in emotional memory formation. However, little is known about their influence during trauma on subsequent recognition memory.

Novelty enhances memory persistence and remediates propranolol-induced deficit via reconsolidation.

Memory reactivation has been shown to open a time window for memory modulation. The majority of the methodological or pharmacological approaches target disruption of reconsolidation to weaken aversive memories. However, methods to improve appetitive memory persistence through reconsolidation or to reverse drug-induced reconsolidation impairment are limited. To improve memory persistence, previous studies show that a novel event, introduced around the time of memory encoding, enables the persistence of an ot...

Neuroevolution of a Modular Memory-Augmented Neural Network for Deep Memory Problems.

We present Modular Memory Units (MMUs), a new class of memory-augmented neural network. MMU builds on the gated neural architecture of Gated Recurrent Units (GRUs) and Long Short Term Memory (LSTMs), to incorporate an external memory block, similar to a Neural Turing Machine (NTM). MMU interacts with the memory block using independent read and write gates that serve to decouple the memory from the central feedforward operation. This allows for regimented memory access and update, administering our network t...

Strength in diversity: Phenotypic, functional, and molecular heterogeneity within the memory B cell repertoire.

The vast majority of vaccines exploit antibody memory to induce lasting immunity. Memory B cells are generated during the initial response to infection, but persist long after the infection has cleared. Immune memory success relies on its adaptability: in response to different pathogens, variants of a single pathogen, and in balancing persistence with reactivation and plasma cell differentiation. This is likely achieved by producing a B cell memory population that is highly diverse, and recent work has high...

Patients' accounts of memory lapses in interactions between neurologists and patients with functional memory disorders.

One of the most commonly made diagnoses in secondary care memory services is functional memory disorder (FMD). FMD is non-progressive and characterised by persistent worries about memory failures without objective evidence of cognitive impairment. This study explores how patients with FMD present their memory concerns. Utilizing video recordings of consultations between patients and neurologists in a memory clinic, we show that FMD patients account for their memory deficits as significant disruptions to the...

Localizing memory functions in brain tumor patients: anatomical hotspots over 260 patients.

Memory complaints are common in brain tumor patients, but is difficult to map memory functions during awake surgery, to preserve them. Thus we analyzed one of the largest data set on clinical, surgical and anatomical correlates of memory in brain tumor patients to date, providing anatomical hotspots for short and long term memory functions.

Relationship between episodic memory and volume of the brain regions of two functional cortical memory systems in multiple sclerosis.

Two functional networks are proposed as neuronal support for the complex processes of memory: the anterior temporal and the medial posterior systems. We examined the atrophy of hippocampus (HC) and of those areas constituting the two functional memory systems in multiple sclerosis (MS) patients with low disability.

Experimental Effects of Acute Exercise on Episodic Memory Function: Considerations for the Timing of Exercise.

Our previous work employing a between-subject randomized controlled trial design suggests that exercising prior to memory encoding is more advantageous in enhancing retrospective episodic memory function when compared to exercise occurring during or after memory encoding. The present experiment evaluates this potential temporal effect of acute exercise on memory function while employing a within-subject, counterbalanced design. In a counterbalanced order (via Latin squares), 24 participants completed four v...

Monkey Memory: Rehearsal Emerges for Novel Images When Familiarity Cues Fade.

It was thought that, when monkeys use familiarity cues to aid recognition memory, they do not engage working memory. A new study shows that, when the value of those familiarity cues is attenuated, monkeys rehearse novel images like familiar ones, a striking parallel with human working memory.

Association between self-reported and performance-based navigational ability using internet-based remote spatial memory assessment.

Traditionally, studies of spatial memory tend to utilise table-top tasks that focus on new spatial learning, however these in-lab procedures may not be reflective of real world spatial memory or navigation. This study investigated the relationship between self-rated navigation abilities and performance on a naturalistic Internet-based assessment of spatial memory for environments learned long ago. Results indicated that self-rated navigation ability was significantly associated with most of the remote spati...

Induction of Autonomous Memory Alveolar Macrophages Requires T Cell Help and Is Critical to Trained Immunity.

Innate immune memory is an emerging area of research. However, innate immune memory at major mucosal sites remains poorly understood. Here, we show that respiratory viral infection induces long-lasting memory alveolar macrophages (AMs). Memory AMs are programed to express high MHC II, a defense-ready gene signature, and increased glycolytic metabolism, and produce, upon re-stimulation, neutrophil chemokines. Using a multitude of approaches, we reveal that the priming, but not maintenance, of memory AMs requ...

Dendritic Inhibition in Layer 1 Cortex Gates Associative Memory.

Learning-related plasticity is critical for emotional memory. In this issue of Neuron,Abs et al., (2018) describe novel dynamics mediated by neurogliaform cells in layer 1 neocortex of mouse that are associated with aversive memory.

Inflammatory Mechanisms Underlying the Effects of Perceived Discrimination on Age-Related Memory Decline.

Previous research suggests that everyday discrimination is associated with worse episodic memory and partially mediates Black-White disparities in memory aging. The biological mechanisms underlying the link between everyday discrimination and memory are unclear but may involve inflammatory processes. This study aimed to determine whether systemic inflammation, indexed by blood levels of C-Reactive Protein (CRP), mediates associations between everyday discrimination and episodic memory over six years.

Trait anxiety is associated with a decreased visual working memory capacity for faces.

Recent work has suggested that anxiety restricts working memory capacity, which may underlie a wide range of cognitive symptoms in anxiety. However, previous literature on the anxiety-visual working memory association yielded mixed results, with some studies demonstrating an anxiety-related increase in visual working memory capacity. In an attempt to gain a more thorough understanding of the relationship between anxiety and visual working memory maintenance function, the current study examined the influence...

The role of sleep in emotional memory processing in middle age.

Sleep benefits memory in young adults, and this effect may be particularly strong for representations associated with negative emotion. Many aspects of sleep important for memory consolidation change with aging, particularly by middle age, suggesting that sleep-related consolidation may be reduced. However, the influence of sleep on memory has rarely been investigated in a middle-aged population. In the current study, young and middle-aged adults viewed negative and neutral pictures and underwent a recognit...

Effects of An Occupational Therapy Memory Strategy Education Group Intervention on Irish Older Adults' Self-Management of Everyday Memory Difficulties.

An occupational therapy memory strategy education group (MSEG) was developed to assist clients with varying levels of memory impairment to adopt strategies to manage memory impairment in their daily lives. Participants were healthy older adults presenting with subjective memory complaints (SMC, n = 14), mild cognitive impairment (MCI, n = 33), or early stages of dementia (n = 13). Clients and their caregivers attended a one-hour session each week for six weeks. Outcome measures were taken at bas...

Manipulation of hippocampal CA3 firing via luminopsins modulates spatial and episodic short-term memory, especially working memory, but not long-term memory.

The CA3 subregion of the hippocampus is important for rapid encoding, storage and retrieval of associative memories. Lesions and pharmacological inhibitions of hippocampal CA3 suggest that it is essential for different memories. However, how CA3 functions in spatial and episodic memory in different time scales (i.e. short-term versus long term) without permanent lesions has not been systematically investigated yet. Taking advantage of the chemogenetic access to opsins, this study used luminopsins, fusion pr...

Theta band network supporting human episodic memory is not activated in the seizure onset zone.

Episodic memory, everyday memory for events, is frequently impaired in patients with epilepsy. We tested patients undergoing intracranial electroencephalography (intracranial EEG) monitoring for the treatment of medically-refractory epilepsy on a well-characterized paradigm that requires episodic memory. We report that an anatomically diffuse network characterized by theta-band (4-7 Hz) coherence is activated at the time of target selection in a task that requires episodic memory. This distinct network of...

A Critical Time-Window for the Selective Induction of Hippocampal Memory Consolidation by a Brief Episode of Slow-Wave Sleep.

Although extensively studied, the exact role of sleep in learning and memory is still not very clear. Sleep deprivation has been most frequently used to explore the effects of sleep on learning and memory, but the results from such studies are inevitably complicated by concurrent stress and distress. Furthermore, it is not clear whether there is a strict time-window between sleep and memory consolidation. In the present study we were able to induce time-locked slow-wave sleep (SWS) in mice by optogeneticall...
