1. Stress and Primary Headache: Review of the Research and Clinical Management.

    Current Pain and Headache Reports 20(7):45 (2016) PMID 27215628

    This review begins with a discussion of the nature of stress and then presents the functional model of primary headache as a framework for conceptualizing the complex relationship between stress and headaches. Research is reviewed on stress as a trigger of headaches and how stress can play a rol...
  2. Connectivity between the OFF bipolar type DB3a and six types of ganglion cell in the marmoset retina.

    Journal of Comparative Neurology 524(9):1839 (2016) PMID 26559914

    Parallel visual pathways originate at the first synapse in the retina, where cones make connections with cone bipolar cells that in turn contact ganglion cells. There are more ganglion cell types than bipolar types, suggesting that there must be divergence from bipolar to ganglion cells. Here we...
  3. Headache symptoms consistent with migraine and tension-type headaches in children with anxiety disorders.

    Journal of Anxiety Disorders 40:67 (2016) PMID 27124732

    To examine the incidence of headache symptoms consistent with migraine and tension-type headache (TTH) in children with anxiety disorders. Parents of children with anxiety disorders (n=27) and children without anxiety disorders (n=36) completed a headache questionnaire based on the International...
  4. Does rumination mediate the relationship between mindfulness and depressive relapse?

    British Journal of Medical Psychology 89(1):33 (2016) PMID 26119013

    Major depressive disorder is a significant mental illness that is highly likely to recur, particularly after three or more previous episodes. Increased mindfulness and decreased rumination have both been associated with decreased depressive relapse. The aim of this study was to investigate wheth...
  5. Identification of AⅡ amacrine, displaced amacrine, and bistratified ganglion cell types in human retina with antibodies against calretinin.

    Journal of Comparative Neurology 524(1):39 (2016) PMID 26053777

    Antibodies against calretinin are markers for one type of rod pathway interneuron (AⅡ amacrine cell) in the retina of some but not all mammalian species. The AⅡ cells play a crucial role in night-time (scotopic) vision and have been proposed as a target for optogenetic restoration of vision in r...
  6. Cognitive behavior therapy for comorbid migraine and/or tension-type headache and major depressive disorder: An exploratory randomized controlled trial.

    Behaviour Research and Therapy 73:8 (2015) PMID 26226090

    Numerous studies have demonstrated comorbidity between migraine and tension-type headache on the one hand, and depression on the other. Presence of depression is a negative prognostic indicator for behavioral treatment of headaches. Despite the recognised comorbidity, there is a limited research...
  7. Analysis of the lateral geniculate nucleus in dichromatic and trichromatic marmosets.

    Journal of Comparative Neurology 523(13):1948 (2015) PMID 25753496

    Marmosets are diurnal New World monkeys that show sex-linked cone photopigment polymorphism, whereby all males and some females are dichromats ("red-green colorblind"), but most females show trichromatic color vision. Here we asked whether trichromats express chromatic-specific circuitry in the ...
  8. Closely related species of birds differ more in body size when their ranges overlap--in warm, but not cool, climates.

    Evolution 69(7):1701 (2015) PMID 26085317

    Differences in body size are widely thought to allow closely related species to coexist in sympatry, but body size also varies as an adaptive response to climate. Here, we use a sister lineage approach to test the prediction that body size differences between closely related species of birds wor...
  9. Color patterns of closely related bird species are more divergent at intermediate levels of breeding-range sympatry.

    American Naturalist 185(4):443 (2015) PMID 25811081

    Closely related species of birds often differ markedly in their color patterns. Here we examine the influence of breeding-range overlap (breeding sympatry) on the evolution of color pattern differences in a sample of closely related bird species. We used a sister-lineage method to analyze 73 phy...
  10. Emergence of complex wave patterns in primate cerebral cortex.

    Journal of Neuroscience 35(11):4657 (2015) PMID 25788682 PMCID PMC4363391

    Slow brain rhythms are attributed to near-simultaneous (synchronous) changes in activity in neuron populations in the brain. Because they are slow and widespread, synchronous rhythms have not been considered crucial for information processing in the waking state. Here we adapted methods from tur...
  11. Analysis of bipolar and amacrine populations in marmoset retina.

    Journal of Comparative Neurology 523(2):313 (2015) PMID 25262625

    About 15 parallel ganglion cell pathways transmit visual signals to the brain, but the interneuron (bipolar and amacrine) populations providing input to ganglion cells remain poorly understood in primate retina. We carried out a quantitative analysis of the inner nuclear layer in the retina of t...
  12. Neuroscience: who needs a parasol at night?

    Current Biology 24(24):R1164 (2014) PMID 25514008

    New measurements of nerve cells in the eye show how very dim lights are processed by night-vision pathways. Copyright © 2014 Elsevier Ltd. All rights reserved.
  13. Behavioral management of the triggers of recurrent headache: a randomized controlled trial.

    Behaviour Research and Therapy 61:1 (2014) PMID 25108482

    This study was designed to evaluate the traditional advice to headache sufferers to avoid all triggers ('Avoidance'), and a novel approach to trigger management (Learning to Cope with Triggers - 'LCT') that included graduated exposure to selected triggers to promote desensitization. Individuals ...
  14. Mindfulness-based cognitive therapy for recurrent depression: A translational research study with 2-year follow-up.

    Australian and New Zealand Journal of Psychiatry 48(8):743 (2014) PMID 24595511

    While mindfulness-based cognitive therapy (MBCT) has demonstrated efficacy in reducing depressive relapse/recurrence over 12-18 months, questions remain around effectiveness, longer-term outcomes, and suitability in combination with medication. The aim of this study was to investigate within a p...
  15. Repeated patterns of trait divergence between closely related dominant and subordinate bird species.

    Ecology 95(8):2334 (2014) PMID 25230483

    Ecologically similar species often compete aggressively for shared resources. These interactions are frequently asymmetric, with one species behaviorally dominant to another and excluding it from preferred resources. Despite the potential importance of this type of interference competition as a ...
  16. Emphysematous cystitis and necrotizing fasciitis.

    Canadian Urological Association Journal 8(7-8):E498 (2014) PMID 25132897 PMCID PMC4113583

    Emphysematous cystitis is an uncommon and often severe infectious condition of the bladder that usually affects women and diabetics. We report a case of a 62-year-old male patient who presented with concomitant emphysematous cystitis and necrotizing fasciitis of the right leg. The patient was in...
  17. Identification of a pathway from the retina to koniocellular layer K1 in the lateral geniculate nucleus of marmoset.

    Journal of Neuroscience 34(11):3821 (2014) PMID 24623761

    Three well characterized pathways in primate vision (midget-parvocellular, parasol-magnocellular, bistratified-koniocellular) have been traced from the first synapse in the retina, through the visual thalamus (lateral geniculate nucleus, LGN), to the visual cortex. Here we identify a pathway fro...
  18. Short wavelength-sensitive cones and the processing of their signals.

    Visual Neuroscience 31(2):111 (2014) PMID 24877202

  19. Distribution and specificity of S-cone ("blue cone") signals in subcortical visual pathways.

    Visual Neuroscience 31(2):177 (2014) PMID 24555883

    We review here the distribution of S-cone signals and properties of S-cone recipient receptive fields in subcortical pathways. Nearly everything we know about S-cone signals in the subcortical visual system comes from the study of visual systems in cats and primates (monkeys); in this review, we...
  20. Characterization of secretagogin-immunoreactive amacrine cells in marmoset retina.

    Journal of Comparative Neurology 522(2):435 (2014) PMID 23852983

    The retina contains at least 30 different types of amacrine cells but not many are well characterized. In the present study the calcium-binding protein secretagogin was localized in a population of regular and displaced amacrine cells in the retina of the common marmoset Callithrix jacchus. Irre...
