Freely chosen and instructed actions are terminated by different neural mechanisms revealed by kinematics-informed EEG.

Neuroimage 2018 Dec 3. Epub 2018 Dec 3.

Cognitive Neuroscience, Institute of Neuroscience and Medicine (INM-3), Research Centre Jülich, 52425, Jülich, Germany; Department of Neurology, University Hospital Cologne, 50924, Cologne, Germany.

Neurophysiological accounts of human volition are dominated by debates on the origin of voluntary choices but the neural consequences that follow such choices remain poorly understood. For instance, could one predict whether or not an action was chosen voluntarily based only on how that action is motorically executed? We investigated this possibility by integrating scalp electroencephalograms and index-finger accelerometer recordings acquired while people chose between pressing a left or right button either freely or as instructed by a visual cue. Even though freely selected and instructed actions were executed with equal vigor, the timing of the movement to release the button was comparatively delayed for freely selected actions. Read More

Adaptive task difficulty influences neural plasticity and transfer of training.

Neuroimage 2018 Dec 3. Epub 2018 Dec 3.

Center for Neuroscience, University of California at Davis, 1544 Newton Court, Davis, CA, 95618, USA; Department of Psychology, University of California at Davis, One Shields Avenue, Davis, CA, 95616, USA.

The efficacy of cognitive training is controversial, and research progress in the field requires an understanding of factors that promote transfer of training gains and their relationship to changes in brain activity. One such factor may be adaptive task difficulty, as adaptivity is predicted to facilitate more efficient processing by creating a prolonged mismatch between the supply of, and the demand upon, neural resources. To test this hypothesis, we measured behavioral and neural plasticity in fMRI sessions before and after 10 sessions of working memory updating (WMU) training, in which the difficulty of practiced tasks either adaptively increased in response to performance or was fixed.

The allosteric dopamine D1 receptor potentiator, DETQ, ameliorates subchronic phencyclidine-induced object recognition memory deficits and enhances cortical acetylcholine efflux in male humanized D1 receptor knock-in mice.

Behav Brain Res 2018 Dec 3. Epub 2018 Dec 3.

Department of Psychiatry and Behavioral Sciences, Northwestern Feinberg School of Medicine, Chicago, IL, 60611, USA.

Diminished dopamine D1 stimulation may contribute to cognitive impairment in Alzheimer's and Parkinson's diseases, schizophrenia, and other neuropsychiatric disorders. However, orthosteric D1 receptor (D1R) agonists produce receptor desensitization and an inverted U-shaped dose-response curve, but positive allosteric modulators (PAMs) do not. We examined the cognitive effects of DETQ, a D1R PAM, in mice genetically modified to express the human D1 receptor ("hD1 mice"). Read More

Department of Pharmacology, University of Michigan, Ann Arbor, MI, USA; Department of Biology, Hope College, Holland, MI, USA; Department of Biomedical Sciences, Western Michigan University Homer Stryker M.D. School of Medicine, Kalamazoo, MI, USA.

Epidemiological data suggest that body mass index and obesity are strong risk factors for depression and anxiety. However, it is difficult to separate cause from effect, as predisposition to obesity may enhance susceptibility to anxiety, or vice versa. Here, we examined the effect of diet and obesity on anxiety-like behaviors in male and female selectively bred obesity-prone and obesity-resistant rats, and outbred Sprague-Dawley rats. Read More

Genetic inactivation of hypoxia inducible factor 1-alpha (HIF-1α) in adult hippocampal progenitors impairs neurogenesis and pattern discrimination learning.

Neurobiol Learn Mem 2018 Dec 3. Epub 2018 Dec 3.

Department of Neuroscience, University of New Mexico Health Sciences Center, Albuquerque, New Mexico. Electronic address:

HIF-1α is a hypoxia-inducible protein that regulates many cellular processes, including neural stem cell maintenance. Previous work demonstrated constitutive stabilization of HIF-1α in neural stem cells (NSCs) of the adult mouse subventricular zone (SVZ) and hippocampal subgranular zone (SGZ). Genetic inactivation of NSC-encoded HIF-1α in the adult SVZ results in gradual loss of NSCs, but whether HIF-1α is required for the maintenance of SGZ hippocampal progenitors and adult hippocampal neurogenesis has not been determined.

Department of Anesthesiology, Perioperative Care and Pain Medicine, New York University School of Medicine, New York, NY, USA; Department of Neuroscience and Physiology, New York University School of Medicine, New York, NY, USA. Electronic address:

Background: Traditional methods to assess pain in rodents depend on measures of nociceptive responses, most commonly from the hind paws. While these measures can quantify nociceptive responses to allow pharmacologic testing, they typically have high inter-experimenter variability and are not time-sensitive enough to correct with neural processes that occur on millisecond scales.

New Method: We have invented a pain detection device that uses changes in skin conductance to measure nocifensive withdrawal responses. Read More

Cracking the Function of Layers in the Sensory Cortex.

Neuron 2018 Dec;100(5):1028-1043

Department of Molecular and Cell Biology, University of California, Berkeley, Berkeley, CA, USA; The Helen Wills Neuroscience Institute, University of California, Berkeley, Berkeley, CA, USA.

Understanding how cortical activity generates sensory perceptions requires a detailed dissection of the function of cortical layers. Despite our relatively extensive knowledge of their anatomy and wiring, we have a limited grasp of what each layer contributes to cortical computation. We need to develop a theory of cortical function that is rooted solidly in each layer's component cell types and fine circuit architecture and produces predictions that can be validated by specific perturbations.

Interleukin-6 inhibition of hERG underlies risk for acquired long QT in cardiac and systemic inflammation.

PLoS One 2018 6;13(12):e0208321. Epub 2018 Dec 6.

Cardiovascular Research Program, VA New York Harbor Healthcare System, Brooklyn, New York, United States of America.

Increased proinflammatory interleukin-6 (IL-6) levels are associated with acquired long QT-syndrome (LQTS) in patients with systemic inflammation, leading to higher risks for life-threatening polymorphic ventricular tachycardia such as Torsades de Pointes. However, the functional and molecular mechanisms of this association are not known. In most cases of acquired LQTS, the target ion channel is the human ether-á-go-go-related gene (hERG) encoding the rapid component of the delayed rectifier K current, IKr, which plays a critical role in cardiac repolarization.

Electrophysiological Properties of Identified Oxytocin and Vasopressin Neurons.

J Neuroendocrinol 2018 Dec 6:e12666. Epub 2018 Dec 6.

Department of Physiology and Biophysics, University of Colorado School of Medicine, Aurora, CO.

To understand the contribution of intrinsic membrane properties to the different firing patterns of oxytocin (OT) and vasopressin (VP) neurons in vivo, in vitro studies are needed, where stable intracellular recordings can be made. Combining immunochemistry for OT and VP and intracellular dye injections allows characterization of identified OT and VP neurons, and several differences between the two cell types have emerged. These include a greater transient K current that delays spiking to stimulus onset, and a higher Na current density leading to greater spike amplitude and a more stable spike threshold, in VP neurons.

The mechanisms that underpin the formation, growth and composition of otoliths, the biomineralized stones in the inner ear of fish, are largely unknown, as only a few fish inner ear proteins have been reported. Using a partial transcriptome for the inner ear of black bream (Acanthopagrus butcheri), in conjunction with proteomic data, we discovered hundreds of previously unknown proteins in the otolith. This allowed us to develop hypotheses to explain the mechanisms of inorganic material supply and daily formation of growth bands. Read More

An embodied neurocomputational framework for organically integrating biopsychosocial processes: An application to the role of social support in health and disease.

Psychosom Med 2018 Dec 5. Epub 2018 Dec 5.

University of Arizona, Departments of Psychiatry, 1501 N. Campbell Ave, Tucson, AZ 85724-5002, United States.

Objective: Two distinct perspectives - typically referred to as the biopsychosocial and biomedical models - currently guide clinical practice. While the role of psychosocial factors in contributing to physical and mental health outcomes is widely recognized, the biomedical model remains dominant. This is due in part to 1) the largely non-mechanistic focus of biopsychosocial research, and 2) the lack of specificity it currently offers in guiding clinicians to focus on social, psychological, and/or biological factors in individual cases.

Signal transduction at vertebrate excitatory synapses involves the rapid activation of AMPA (a-amino-3-hydroxy-5-methyl-4-isoxazole propionate) receptors, glutamate-gated ion channels whose four subunits assemble as a dimer-of-dimers. Technical advances in cryo-electron microscopy brought a slew of full-length structures of AMPA receptors, on their own and in combination with auxiliary subunits. These structures indicate that dimers might undergo substantial lateral motions during gating, opening up the extracellular layer along the central 2-fold symmetry axis. Read More

Treatment-resistant and multi-therapy-resistant criteria for bipolar depression: consensus definition.

Br J Psychiatry 2018 Dec 6:1-9. Epub 2018 Dec 6.

Clinical Senior Lecturer in Mood Disorders and Consultant Psychiatrist,National Affective Disorders Service; Academic Psychiatry Training Programme Lead,Institute of Psychiatry,Psychology and Neuroscience,King's College London,South London and Maudsley NHS Foundation Trust (SLaM); andCRN South London Lead for Mental Health,Centre for Affective Disorders, Institute of Psychiatry,Psychology and Neuroscience,King's College London,South London and Maudsley NHS Foundation Trust (SLaM),UK.

Background: Most people with bipolar disorder spend a significant percentage of their lifetime experiencing either subsyndromal depressive symptoms or major depressive episodes, which contribute greatly to the high levels of disability and mortality associated with the disorder. Despite the importance of bipolar depression, there are only a small number of recognised treatment options available. Consecutive treatment failures can quickly exhaust these options leading to treatment-resistant bipolar depression (TRBD). Read More

Mindfulness is positively related to socioeconomic job status and income and independently predicts mental distress in a long-term perspective: Danish validation studies of the Five-Factor Mindfulness Questionnaire.

Psychol Assess 2018 Dec 6. Epub 2018 Dec 6.

Neurobiology Research Unit, The Neuroscience Centre, Rigshospitalet, Copenhagen, Denmark, and Center for Integrated Molecular Brain Imaging.

The Five Factor Mindfulness Questionnaire (FFMQ) measures 5 factor-analytically derived mindfulness aspects (Observe, Describe, Non-Judgment, Non-Reactivity, and Acting with Awareness) and is commonly used as an indicator of mindfulness in population surveys and studies of mindfulness-based interventions (MBI). Outside MBI, FFMQ scores are hypothesized to reflect relatively stable human dispositions of importance to psychological health. However, the long-term test-retest reliability of FFMQ scores is virtually untested and it remains unknown whether FFMQ scores predict psychological health after controlling for standardized socioeconomic status classifications.

Family-based treatment: Where are we and where should we be going to improve recovery in child and adolescent eating disorders.

Int J Eat Disord 2018 Dec 6. Epub 2018 Dec 6.

Department of Psychiatry and UCSF Weill Institute for Neurosciences, University of California, San Francisco, California.

Objective: Family therapy has long been advocated as an effective intervention for eating disorders. A specific form of family therapy, one that utilizes family resources, has proven especially effective for adolescents with anorexia or bulimia nervosa (AN and BN). First developed in London, a behaviorally focused adaptation, called family-based treatment (FBT), has been manualized and systematically studied in six randomized clinical trials for adolescent AN and two for adolescent BN.

Potential of Exosomes for the Treatment of Stroke.

Cell Transplant 2018 Dec 6:963689718816990. Epub 2018 Dec 6.

1 Department of Anatomy, Histology and Embryology, Discipline of Neuroscience, Shanghai Jiao Tong University School of Medicine, Shanghai, China.

Stroke is the result of blockage or rupture of blood vessels in the brain and is the leading cause of death and disability in the world. Currently only a very limited number of therapeutic approaches are available for treatment of stroke patients, and the vast majority of neuroprotective agents that tested positively in pre-clinical studies failed in clinical trials. In recent years, the clinical value of the use of exosomes for stroke treatment has received widespread attention due their unique characteristics such as low immunogenicity, low toxicity and biodegradability, ability to cross the blood-brain barrier (BBB), and their important role in communication between cells.

The impact of the implementation of the Dutch combined Meeting Centres Support Programme for family caregivers of people with dementia in Italy, Poland and UK.

Aging Ment Health 2018 Dec 6:1-11. Epub 2018 Dec 6.

j Department of Psychiatry , VU University Medical Centre , Amsterdam , The Netherlands.

Objectives: The MEETINGDEM research project aimed to implement the combined Dutch Meeting Centre Support Programme (MCSP) for community-dwelling people with dementia and caregivers within Italy, Poland and UK and to assess whether comparable benefits were found in these countries as in the Netherlands.

Method: Nine pilot Meeting Centres (MCs) participated (Italy-5, Poland-2, UK-2). Effectiveness of MCSP was compared to usual care (UC) on caregiver outcomes measuring competence (SSCQ), mental health (GHQ-12), emotional distress (NPI-Q) and loneliness (UCLA) analysed by ANCOVAs in a 6-month pre-test/post-test controlled trial.

Neural correlates of the effect of implementation intention on prospective memory.

Psych J 2018 Dec 5. Epub 2018 Dec 5.

Neuropsychology and Applied Cognitive Neuroscience Laboratory, CAS Key Laboratory of Mental Health, Institute of Psychology, Beijing, China.

Prospective memory (PM) refers to the ability to remember to do something in the future. Implementation intention refers to a self-regulatory strategy in the form of "If …, then …" planning that can improve PM performance. However, the neural basis of the effect of implementation intention on PM remains unclear, as do the phases of PM that are affected by implementation intention. Read More

Reduced capacity for empathy in corticobasal syndrome and its impact on carer burden.

Int J Geriatr Psychiatry 2018 Dec 5. Epub 2018 Dec 5.

The University of Sydney, Brain and Mind Centre.

Corticobasal syndrome (CBS) is clinically characterised by a wide range of motor, cognitive, and behavioural features but remains challenging to diagnose accurately. Despite recent evidence supporting the presence of social cognition and emotion processing disturbances, few studies have explored the nature of empathic ability in CBS. This study aimed to: (i) investigate the extent to which cognitive and affective dimensions of empathy are affected in CBS, and (ii) to determine the impact of such changes on carer burden.
