Respiratory sinus arrhythmia, negative social interactions, and fluctuations in unmet interpersonal needs: A daily diary study

Author(s): MacNeil S; Renaud J; Gouin JP;

Introduction: This study examined daily fluctuations in the unmet interpersonal needs of thwarted belongingness and perceived burdensomeness in response to daily negative social interactions, as well as the moderating role of respiratory sinus arrhythmia (R ...

Respiratory sinus arrhythmia moderates the interpersonal consequences of brooding rumination

Author(s): Caldwell W; MacNeil S; Wrosch C; McGrath JJ; Dang-Vu TT; Morin AJS; Gouin JP;

Brooding rumination is an intrapersonal emotion regulation strategy associated with negative interpersonal consequences. Resting respiratory sinus arrhythmia (RSA), a psychophysiological marker of self-regulatory capacity, may buffer the association between ...

Sleep disorders in patients with a neurocognitive disorder

Author(s): C Moderie

CONCLUSION: Multiple and sustained nonpharmacological approaches are recommended for the treatment of sleep disturbances in patients with neurocognitive disorder. Pharmacological indications remain limited, and further randomized clinical trials integrating ...

Maturation of temporal saccade prediction from childhood to adulthood: predictive saccades, reduced pupil size and blink synchronization

Author(s): Calancie OG; Brien DC; Huang J; Coe BC; Booij L; Khalid-Khan S; Munoz DP;

When presented with a periodic stimulus, humans spontaneously adjust their movements from reacting to predicting the timing of its arrival, but little is known about how this sensorimotor adaptation changes across development. To investigate this, we analyz ...

In utero Exposure to Valproic-Acid Alters Circadian Organisation and Clock-Gene Expression: Implications for Autism Spectrum Disorders

Author(s): Ferraro S; de Zavalia N; Belforte N; Amir S;

Autism Spectrum Disorder (ASD) is a pervasive neurodevelopmental disorder characterised by restrictive patterns of behaviour and alterations in social interaction and communication. Up to 80% of children with ASD exhibit sleep-wake cycle disturbances, empha ...

Heart rate variability moderates the between- and within-person associations between daily stress and negative affect

Author(s): da Estrela C; MacNeil S; Gouin JP;

Stress exposure increases risk for depressive symptoms. However, there are substantial individual differences in affective responses to stress. High-frequency heart rate variability (HF-HRV), a marker of vagally-mediated parasympathetic activity, has been c ...

Cerebellar Cortex 4-12 Hz Oscillations and Unit Phase Relation in the Awake Rat.

Author(s): Lévesque M; Gao H; Southward C; Langlois JMP; Léna C; Courtemanche R;

Oscillations in the granule cell layer (GCL) of the cerebellar cortex have been related to behavior and could facilitate communication with the cerebral cortex. These local field potential (LFP) oscillations, strong at 4-12 Hz in the rodent cerebellar corte ...

The phenotype associated with variants in TANGO2 may be explained by a dual role of the protein in ER-to-Golgi transport and at the mitochondria.

Author(s): Milev MP, Saint-Dic D, Zardoui K, Klopstock T, Law C, Distelmaier F, Sacher M

TANGO2 variants result in a complex disease phenotype consisting of recurrent crisis-induced rhabdomyolysis, encephalopathy, seizures, lactic acidosis, hypoglycemia, and cardiac arrhythmias. Although first described in a fruit fly model as a protein necessa ...

Author(s): da Estrela C; McGrath J; Booij L; Gouin JP;

Background: Disrupted sleep quality is one of the proposed mechanisms through which chronic stress may lead to depression. However, there exist significant individual differences in sleep reactivity, which is the extent to which one experiences sleep distur ...
