Can repeated intranasal oxytocin administration affect reduced neural sensitivity towards expressive faces in autism? A randomized controlled trial
Paper from the JCPP – ‘Autism spectrum disorder (ASD) is a neurodevelopmental condition characterized by difficulties in social communication and interaction. Crucial for efficient social interaction is the ability to quickly and accurately extract information from a person’s face.’ Matthijs Moerkerke (pic) et al.

EEG data might help identify children at risk for social anxiety
Electroencephalography (EEG) is a non-invasive method to monitor the electrical activity of the brain. There are five main broad frequency bands in the EEG power spectrum: alpha, beta, gamma, delta and theta. Data suggest that EEG-derived delta–beta coupling — indicating related activity in the delta and beta frequency bands — might serve as a marker of emotion regulation.

Coupled delta-beta wave activity might predict social anxiety in children
Researchers from McMaster University, Canada, have examined whether individual differences in salivary cortisol levels at baseline and parent-reported social anxiety levels are associated with resting, coupled delta–beta frontal wave activity.

Working memory deficits may compromise cognitive flexibility in OCD
Obsessive compulsive disorder (OCD) is characterised by recurrent intrusive thoughts and/or behaviours. These traits imply deficits in cognitive flexibility in affected patients, but it is unclear at what stage of information processing these deficits might emerge. To address this question, Nicole Wolff and colleagues asked 25 adolescents with OCD and 25 matched healthy controls to complete a computer-based task switching paradigm.

Cognitive flexibility in OCD: challenging the paradigm
Data from a new study by Nicole Wolff and colleagues suggest that cognitive flexibility can be better in children with obsessive-compulsive disorder (OCD) than typically developing controls.

MEG confirms hyper-vigilance followed by threat avoidance in children with anxiety disorder
A key etiological factor of anxiety disorders is an altered pattern of threat processing, but its neurobiological basis is relatively unclear.
