Aberrant cortical activity in 5xFAD mice in response to social and non-social olfactory stimuli (Postprint)
Background: Neuroimaging studies investigating the behavioural and psychological symptoms of dementia (BPSD)—such as apathy, anxiety, and depression— have linked some of these symptoms with altered neural activity. However, ... -
The Acceptability of Deception in Pediatric Research
Objective: Deception has been used to investigate the role of developmental and behavioral factors in child health; however, its acceptability for use in pediatric research has received little empirical attention. This ... -
Age of Onset and Duration of Deafness Drive Brain Organization for Biological Motion Perception in Non-Signers
We used fMRI to characterize the neural responses to biological motion in adults who became deaf at a wide range of ages, none of whom were fluent sign language users. Although hearing people showed stronger activation for ... -
Caregiver accuracy in detecting deception in facial expressions of pain in children
Facial expressions provide a primary source of inference about a child’s pain. Although facial expressions typically appear spontaneous, children have some capacity to fake or suppress displays of pain, thereby potentially ... -
Children’s Fear during Procedural Pain: Preliminary Investigation of the Children’s Fear Scale
Many children consider getting a needle to be one of their most feared and painful experiences. Differentiating between a child’s experience of fear and pain is critical to appropriate intervention. There is no gold standard ... -
Clinical management of behavioral insomnia of childhood
Behavioral insomnia is highly prevalent, affecting approximately 25% of children. It involves difficulties initiating and maintaining sleep and frequently results in inadequate sleep, leading to an array of negative ... -
Cognitive Behavioural Therapy for Pediatric Chronic Pain: The Problem, Research, and Practice
The purpose of this paper is to outline the rationale and use of cognitive-behavioural therapy (CBT) for the treatment of pediatric chronic pain. The paper begins by demonstrating the scope and impact of the problem of ... -
Contemporary Use of the Cold Pressor Task in Pediatric Pain Research: A Systematic Review of Methods
The cold pressor task (CPT) is an ethical experimental pain task widely used by pediatric pain researchers to examine a variety of important theoretical and clinical questions. The purpose of this systematic review was to ... -
Dalhousie dyspnea scales: construct and content validity of pictorial scales for measuring dyspnea
BACKGROUND: Because there are no child-friendly, validated, self-report measures of dyspnea or breathlessness, we developed, and provided initial validation, of three, 7-item, pictorial scales depicting three sub-constructs ... -
Differential expression of Hdac2 in male and female mice of differing social status
Mice naturally form social hierarchies and their experiences as subordinate or dominant mice inform future behavioural strategies. To better understand the neural bases of social dominance, we investigated hippocampal gene ... -
Drosophila ABC transporter mutants white, brown and scarlet have altered contents and distribution of biogenic amines in the brain
Monoamines such as dopamine, histamine and serotonin (5-HT) are widely distributed throughout the brain of the fruit fly Drosophila melanogaster, where many of their actions have been investigated. For example, histamine ... -
Dyadic analysis of child and parent trait and state pain catastrophizing in the process of children's pain communication
Explored separately, child and parent catastrophic thoughts about child pain show robust negative relations with child pain. The objective of this study was to conduct a dyadic analysis to elucidate intra- and inter-personal ... -

The epidemiology of chronic pain in children and adolescents revisited: A systematic review
Chronic and recurrent pain not associated with a disease are very common in childhood and adolescence, but studies of pain prevalence have yielded inconsistent findings. This systematic review examined studies of chronic ... -
Hopelessness and Excessive Drinking among Aboriginal Adolescents: The Mediating Roles of Depressive Symptoms and Drinking to Cope
Canadian Aboriginal youth show high rates of excessive drinking, hopelessness, and depressive symptoms. We propose that Aboriginal adolescents with higher levels of hopelessness are more susceptible to depressive symptoms, ... -
Impact of threat level, task instruction, and individual characteristics on cold pressor pain and fear among children and their parents
The cold pressor task (CPT) is increasingly used to induce experimental pain in children, but the specific methodology of the CPT is quite variable across pediatric studies. This study examined how subtle variations in CPT ...
