Narcolepsy is the most common neurological cause of chronic sleepiness. The discovery about 20 years ago that narcolepsy is caused by selective loss of the neurons producing orexins (also known as hypocretins) sparked great advances in the field. Here, we review the current understanding of how orexin neurons regulate sleep-wake behaviour and the consequences of the loss of orexin neurons. We also summarize the developing evidence that narcolepsy is an autoimmune disorder that may be caused by a T cell-mediated attack on the orexin neurons and explain how these new perspectives can inform better therapeutic approaches...

AIM: To examine: (1) relationships between brain structure, and concurrently assessed neurological and behavioural functioning, in infants born preterm at term-equivalent age (TEA; approximately 38-44wks); and (2) whether brain structure-function relationships differ between infants born very (24-29wks) and moderate-late (32-36wks) preterm. METHOD: A total of 257 infants (91 very preterm, 166 moderate-late preterm; 120 males, 137 females) had structural magnetic resonance imaging (MRI) and neurological and behavioural assessments (Prechtl's general movements assessment, Neonatal Intensive Care Unit Network Neurobehavioral Scale [NNNS] and Hammersmith Neonatal Neurological Examination [HNNE])...

Mindfulness-based training reduces pain in clinical and experimental settings. Evidence suggests these beneficial effects are facilitated via increased focus on the present moment, and reduced emotional enhancement of pain. The majority of the existing literature has focused on mindfulness as a learned skill, and on the neural mechanisms that underlie the acquisition of this skill. It is unknown whether similar mechanisms are associated with trait mindfulness in the absence of training and whether these mechanisms confer the ability to cope with pain...

A major component of cognitive control is the ability to act flexibly in the environment by either behaving automatically or inhibiting an automatic behaviour. The interleaved pro/anti-saccade task measures cognitive control because the task relies on one's abilities to switch flexibly between pro and anti-saccades, and inhibit automatic saccades during anti-saccade trials. Decline in cognitive control occurs during aging or neurological illnesses such as Parkinson's disease (PD), and indicates decline in other cognitive abilities, such as memory...

Employee deviance and time theft is an expensive and pervasive workplace problem. Research indicates that a primary reason employees engage in deviant behaviour is the perception of injustice often associated with psychological contract breach (i.e., broken promises). This study used a rodent model to mimic said experience of broken promises and then examined the subsequent neurophysiological changes that lead to the display of deviant behaviours. Specifically, we generated a psychological contract using a 3 choice serial reaction task, then broke the promise, and finally examined deviant behaviours and neurological correlates...

BACKGROUND: Sensory interventions are prevalent amongst adult mental health practitioners and are supported by major stakeholders and policy makers across the world. The term commonly used by occupational therapists applying sensory practices is sensory modulation, however this term has evolved. AIMS: This paper aims to investigate and clarify the definition of 'sensory modulation' for application by occupational therapists. METHOD: A framework guided this concept analysis on sensory modulation...

Functional neurological disorder (FND) is a common and highly disabling disorder, but its aetiology remains enigmatic. Conceptually, there has been reduced emphasis on the role of psychosocial stressors in recent years, with a corresponding increase in neurobiological explanations. However, a wealth of evidence supports the role of psychosocial adversities (eg, stressful life events, interpersonal difficulties) as important risk factors for FND. Therefore, there is a need to integrate psychosocial (environmental) and neurobiological factors (eg, sensorimotor and cognitive functions) in contemporary models of FND...

BACKGROUND: Disorders affecting mental health are highly prevalent, can be disabling, and are associated with substantial premature mortality. Yet national health system responses are frequently under-resourced, inefficient, and ineffective, leading to an imbalance between disease burden and health expenditures. We estimated the disease burden in the Americas caused by disorders affecting mental health. This measure was adjusted to include mental, neurological, and behavioural disorders that are frequently not included in estimates of mental health burden...

Eliciting predictable flight responses in insects via exogenous stimulation of the nervous system is an area of both scientific and engineering interest. Blowflies in particular possess an excellent biological flight control system, making them an ideal system for characterising responses to stimulation. Here we demonstrate a means of electrically controlling Calliphoridae-Protophormia terranovae wing behaviour, generating a repeatable yaw response via biphasic electrical stimulation of the H1 lobula plate tangential cell (LPTC)...

Microtubules are cytoskeletal elements with important cellular functions, whose dynamic behaviour and properties are in part regulated by microtubule-associated proteins (MAPs). The building block of microtubules is tubulin, a heterodimer of α- and β-tubulin subunits. Longitudinal interactions between tubulin dimers facilitate a head-to-tail arrangement of dimers into protofilaments, while lateral interactions allow the formation of a hollow microtubule tube that mostly contains 13 protofilaments. Highly homologous α- and β-tubulin isotypes exist, which are encoded by multi-gene families...

Wilson's Disease is an inborn error of metabolism associated with accumulation of copper in the body manifesting as hepatic, neurological and behavioural symptoms. Almost 20% patients initially present with behavioural symptoms such as depression, personality changes or even mania. Schizophrenia and catatonia are less common. We describe the case of a 35 year old female with behavioural abnormalities diagnosed as a case of Schizophrenia and started on antipsychotics, which led to further worsening of her primary complaints...

Acquired language disorders after stroke are strongly associated with left hemisphere damage. When language difficulties are observed in the context of right hemisphere strokes, patients are usually considered to have atypical functional anatomy. By systematically integrating behavioural and lesion data from brain damaged patients with functional MRI data from neurologically normal participants, we investigated when and why right hemisphere strokes cause language disorders. Experiment 1 studied right-handed patients with unilateral strokes that damaged the right (n = 109) or left (n = 369) hemispheres...

PURPOSE: The objective of this study was to determine the extent to which the dual-process theory of medical diagnosis enjoys neuroscientific support. To that end, the study explored whether neurological correlates of system-2 thinking could be located in the brain. It was hypothesised that system-2 thinking could be observed as the activation of the prefrontal cortex. METHOD: An experimental paradigm was applied that consisted of a learning and a test phase. During the learning phase, 22 medical students were trained in diagnosing chest X-rays...

BACKGROUND: Coping positively and negatively influences psychosocial and other outcomes in multiple sclerosis (MS), but there is conflicting evidence about the use of different coping strategies and their associations with demographic and disease characteristics. Our aims were to examine which coping strategies are used by a large sample of people with MS, then to identify any associations between demographic and disease related factors with use of individual coping strategies. METHODS: Participants in the Trajectories of Outcomes in Neurological Conditions (TONiC) study completed the Coping Orientations to Problems Experienced (COPE60) questionnaire...

Mucopolysaccharydosis IIIB is the second most frequent form of Sanfilippo syndrome, a degenerative, pediatric lysosomal storage disease (LSD) characterized by severe neurological disorders and death. We have generated two iPSCs lines derived from dermal fibroblast from a MPSIIIB homozygous (P358L) donor. Cells were reprogrammed with OriP/EBNA1-based episomal plasmids containing: OCT3/4, SOX2, KLF4, L-MYC, LIN28, BCL-xL and shp53. Both cell lines are homozygous for the P358L mutation of the α-N-acetylglucosaminidase (NAGLU) gene, have normal karyotype, are free of plasmid integration, express high levels of pluripotency-associated markers and can differentiate into the three germ layers...

In this paper we investigate the changes in the functional connectivity intensity, and some related properties, in healthy people, across the life span and at resting state. For the explicit computation of the functional connectivity we exploit a recently proposed model, that bases not only on the correlations data provided by the acquisition equipment, but also on different parameters, such as the anatomical distances between nodes and their degrees. The leading purpose of the paper is to show that the proposed approach is able to recover the main aspects of resting state condition known from the available literature, as well as to suggest new insights, perspectives and speculations from a neurobiological point of view...
