Background: Bruxism is characterized by tooth grinding and/or clenching.
Aim: To evaluate the association between possible awake bruxism (PAB) and bullying among individuals aged 8-11 years.
Design: A representative cross-sectional study was conducted with 434 eight- to eleven-year-old children/adolescents. Parents/caregivers answered a questionnaire to provide data on sociodemographic characteristics. Children/adolescents answered a questionnaire about the occurrence of PAB. The Olweus Bully/Victim Questionnaire was used. The Poisson regression analysis was performed.
Results: Of the 434 children/adolescents, 209 (48.2%) were boys and 225 (51.8%) were girls. The mean age of the children/adolescents was 9.14 years (±1.00). Children/adolescents who were victims of bullying (PR = 1.52, 95% CI = 1.14-2.04, P = .005) and bullies-victims (PR = 2.08, 95% CI = 1.36-3.17, P = .001) presented a higher frequency of PAB than those who were not involved in bullying.
Conclusion: Children/adolescents who were bullying victims and bullies-victims had a higher frequency of PAB.

Background: Fragile X syndrome (FXS) is a leading known genetic cause of intellectual disability and autism spectrum disorders (ASD)-associated behaviors. A consistent and debilitating phenotype of FXS is auditory hypersensitivity that may lead to delayed language and high anxiety. Consistent with findings in FXS human studies, the mouse model of FXS, the Fmr1 knock out (KO) mouse, shows auditory hypersensitivity and temporal processing deficits.

Objective: Monoallelic variants in the transient receptor potential melastatin-related type 3 gene (TRPM3) have been associated with neurodevelopmental manifestations, but knowledge on the clinical manifestations and treatment options is limited. We characterized the clinical spectrum, highlighting particularly the epilepsy phenotype, and the effect of treatments.
Methods: We analyzed retrospectively the phenotypes and genotypes of 43 individuals with TRPM3 variants, acquired from GeneMatcher and collaborations (n = 21), and through a systematic literature search (n = 22).

The brain is always intrinsically active, using energy at high rates while cycling through global functional modes. Awake brain modes are tied to corresponding behavioural states. During goal-directed behaviour, the brain enters an action-mode of function.

Objectives: The cerebral cortex contains neurons that play a pivotal role in controlling rhythmic masticatory jaw movements. However, the population characteristics of individual cortical neuronal activity during mastication and the impact of tooth loss on these characteristics remain unclear. Thus, in this study, we aimed to determine the activity patterns of mastication-related motor cortical neurons elicited during mastication and examine the effects of tooth extraction on neuronal activity using two-photon Ca imaging in head-restrained awake mice.

Cortical spreading depolarization (CSD), a slowly propagating wave of transient cellular depolarization, is a reliable cortical response to various brain insults (stroke, trauma, seizures) and underlying mechanism of migraine aura. Little is known about CSD effects on brain network activity. Using undirected (mutual information, MI) and directed (transfer entropy, TE) measures, we studied the dynamics of cross-hemispheric connectivity associated with the development of unilateral CSD in freely behaving rats and the involvement of inhibitory transmission in mechanisms of the coupling changes.
