The neural basis of how learned vocalizations change during development and in adulthood represents a major challenge facing cognitive neuroscience. This plasticity in the degree to which learned vocalizations can change in both humans and songbirds is linked to the actions of sex steroid hormones during ontogeny but also in adulthood in the context of seasonal changes in birdsong. We investigated the role of steroid hormone signaling in the brain on distinct features of birdsong using adult male canaries (Serinus canaria), which show extensive seasonal vocal plasticity as adults...

Americans are suffering from a culture of taking pills. Six out of ten Americans utilize at least one prescription drug, and more than one in ten use five or more prescription medicines. Although this torrent of taking pills is already high, drug use in the USA has not yet crested. Prescription drugs have specific targets, but often they adversely affect other tissues and organs. In keeping with the mission of the recently named National Center for Complementary and Integrative Health (NCCIH), Brain, Behavior, and Immunity searches for the underlying cause and potential efficacy of both drug and non-drug interventions...

Parkinson's disease (PD), a neurodegenerative disorder, affects millions of people and has gained attention because of its clinical roles affecting behaviors related to motor and nonmotor symptoms. Although studies on PD from various aspects are becoming popular, few rely on predictive systems modeling approaches. Using Biochemical Systems Theory (BST), this article attempts to model and characterize dopaminergic cell death and understand pathophysiology of progression of PD. PD pathways were modeled using stochastic differential equations incorporating law of mass action, and initial concentrations for the modeled proteins were obtained from literature...

Emotionally Focused Therapy for Couples (EFT) is an evidence-based couple therapy based in attachment theory. Research has amassed over the past three decades pointing to the role of relationships in health and and well-being. Affective neuroscience suggests that secure relationships appear to foster adaptive stress co-regulation. The effectiveness of EFT has been demonstrated in couples facing high levels of stress, and has been shown to reduce depressive and post-traumatic stress symptoms. Furthermore, EFT has been shown to help couples regulate their neurophysiological stress response...

Heterogeneity of the posterior alpha rhythm (AR) is a widely assumed but rarely tested phenomenon. We decomposed the posterior AR in the cortical source space with a 3-way PARAFAC technique, taking into account the spatial, frequency, and temporal aspects of mid-density EEG. We found a multicomponent AR structure in 90% of a group of 29 healthy adults. The typical resting-state structure consisted of a high-frequency occipito-parietal component of the AR (ARC1) and a low-frequency occipito-temporal component (ARC2), characterized by individual dynamics in time...

PURPOSE: Sensory approaches to mental illness are increasingly prominent in occupational therapy. Despite indicators of efficacy, a paucity of literature supports these approaches. This article provides a scoping review of research on the relationship between sensory processing and mental illness. METHOD: Using Arksey and O'Malley's (2005) framework, we mapped this area of research and identified gaps in the knowledge base. We searched PubMed, CINAHL Plus, PsycINFO, OTseeker, and the Cochrane Library using the terms sensory and mental health...

PURPOSE OF REVIEW: Sexual dysfunction is a frequent issue in patients with affective disorders, affecting its quality of life and posing challenges to the approach of these patients. RECENT FINDINGS: In recent years, human sexuality has attracted interest from the scientific community, and today we have a much deeper knowledge of the mechanisms involved in the sexual response. Paraphilias or sexual dysfunctions like low sexual desire, premature ejaculation, and erectile dysfunction, are frequent in affective disorders, and the frequency of each sexual problem varies according to the affective disorder...

PURPOSE OF THE STUDY: The aim of the study was to propose "the risk formula" for obstructive sleep apnea in children according to the general and local clinical parameters and findings relevant for obstructive sleep apnea (OSA) severity. The unmet need for this formula arises from the economic burden of polysomnography (device, staff, training, special sleep centers, etc) as the golden standard for the diagnostics. MATERIALS AND METHODS USED: The study was performed from January 2013 until January 2016 in the Sleep Center, Department for Neuroscience, School of Medicine of the University of Split, Department of Pediatrics, University Hospital Split, Croatia and ENT Dept...

Taste stimuli have a temperature that can stimulate thermosensitive neural machinery in the mouth during gustatory experience. Although taste and oral temperature are sometimes discussed as different oral sensory modalities, there is a body of literature that demonstrates temperature is an important component and modulator of the intensity of gustatory neural and perceptual responses. Available data indicate that the influence of temperature on taste, herein referred to as "thermogustation", can vary across taste qualities, can also vary among stimuli presumed to share a common taste quality, and is conditioned on taste stimulus concentration, with neuronal and psychophysical data revealing larger modulatory effects of temperature on gustatory responding to weakened taste solutions compared to concentrated...

To date, most investigations in the field of affective neuroscience mainly focused on the processing of facial expressions, overlooking the exploration of emotional body language (EBL), its capability to express our emotions notwithstanding. Few electrophysiological studies investigated the time course and the neural correlates of EBL and the integration of face and body emotion-related information. The aim of the present study was to investigate both the time course and the neural correlates underlying the integration of affective information conveyed by faces and bodies...

REVIEW
Henri Leinonen, Heikki Tanila
Mice and rats are nocturnal mammals and their vision is specialized for detection of motion and contrast in dim light conditions. These species possess a large proportion of UV-sensitive cones in their retinas and the majority of their optic nerve axons target superior colliculus rather than visual cortex. Therefore, it was a widely held belief that laboratory rodents hardly utilize vision during day-time behavior. This dogma is being questioned as accumulating evidence suggests that laboratory rodents are able to perform complex visual functions, such as perceiving subjective contours, and that declined vision may affect their performance in many behavioral tasks...

The casper strain of zebrafish is widely used in studies ranging from cancer to neuroscience. casper offers the advantage of relative transparency throughout adulthood, making it particularly useful for in vivo imaging by epifluorescence, confocal, and light sheet microscopy. casper was developed by selective breeding of two previously described recessive pigment mutants: 1) nacre, which harbors an inactivating mutation of the mitfa gene, rendering the fish devoid of pigmented melanocytes; and 2) roy orbison, a mutant with so-far unidentified genetic cause that lacks reflective iridophores...

Vicarious pain perception has been an influential paradigm for investigating the social neuroscience of empathy. This research has highlighted the importance of both shared representations (i.e., involved in both experiencing first-hand physical pain and observing pain) and mechanisms that discriminate between self and other. The majority of this research has been conducted in healthy younger adults using a group-average approach. There are, however, known inter-individual differences that can contribute to vicarious experience...

OBJECTIVE: Spondylodiscitis is a rare inflammatory syndrome affecting intervertebral discs and adjacent vertebral bodies. Without appropriate therapy, many serious complications such as secondary spinal epidural abscess (SEA) may prolong recovery time. The aim of the study is to compare the main characteristics of our patients to the international literature and to analyze the impact of complications associated with spondylodiscitis concerning clinical outcome. METHODS: We designed a retrospective study based on patients of the National Institute of Clinical Neurosciences, Hungary, between 2008 and 2015...

Social neuroscience, the study of the neurobiological basis of social behavior, has become a major area of current research in behavioral neuroscience and psychiatry, since many psychiatric disorders are characterized by social deficits. Social behavior refers to the behavioral response with regard to socially relevant information, and requires the perception and integration of social cues through a complex cognition process (i.e. social cognition) that involves attention, memory, motivation and emotion. Neurobiological and molecular mechanisms underlying social behavior are highly conserved across species, and inter- and intra-specific variability observed in social behavior can be explained to large extent by differential activity of this conserved neural network...

Subclinical narcissism is a personality trait with two faces: According to social-cognitive theories it is associated with grandiosity and feelings of superiority, whereas psychodynamic theories emphasize vulnerable aspects like fluctuating self-esteem and emotional conflicts. The psychodynamic view, however, is commonly not supported by self-report studies on subclinical narcissism. Personality neuroscience might help to better understand the phenomenon of narcissism beyond the limits of self-report research...

OBJECTIVE: The advent of High-Performance Computing (HPC) in recent years has led to its increasing use in brain study through computational models. The scale and complexity of such models are constantly increasing, leading to challenging computational requirements. Even though modern HPC platforms can often deal with such challenges, the vast diversity of the modeling field does not permit for a homogeneous acceleration platform to effectively address the complete array of modeling requirements...

Evidence for endemically low statistical power has recently cast neuroscience findings into doubt. If low statistical power plagues neuroscience, this reduces confidence in reported effects. However, if statistical power is not uniformly low, such blanket mistrust might not be warranted. Here, we provide a different perspective on this issue, analysing data from an influential paper reporting a median power of 21% across 49 meta-analyses (Button et al., 2013). We demonstrate, using Gaussian mixture modelling, that the sample of 730 studies included in that analysis comprises several subcomponents; therefore the use of a single summary statistic is insufficient to characterise the nature of the distribution...

A hallmark feature of episodic memory is that of "mental time travel," whereby an individual feels they have returned to a prior moment in time. Cognitive and behavioral neuroscience methods have revealed a neurobiological counterpart: Successful retrieval often is associated with reactivation of a prior brain state. We review the emerging literature on memory reactivation and recapitulation, and we describe evidence for the effects of emotion on these processes. Based on this review, we propose a new model: Negative Emotional Valence Enhances Recapitulation (NEVER)...
