The impact of oxytocin administration on brain activity: a systematic review and meta-analysis protocol

Converging evidence demonstrates the important role of the neuropeptide hormone oxytocin (OT) in human behaviour and cognition. Intranasal OT administration has been shown to improve several aspects of social communication, such as the theory of mind …

Contribution of oxytocin receptor polymorphisms to amygdala activation in schizophrenia spectrum disorders

Background: Oxytocin has been proposed to mediate amygdala dysfunction associated with altered emotion processing in schizophrenia, but the contribution of oxytocin pathway genes is yet to be investigated. Aims: To identify potential different …

Intranasal oxytocin mechanisms can be better understood but its effects on social cognition and behavior are not to be sniffed at

The administration of intranasal oxytocin (OT) has demonstrated a wide range of effects on social behavior and cognition, which has led to its proposed use as a treatment for psychiatric disorders characterized by social cognition deficits. Leng and …

Low dose intranasal oxytocin delivered with Breath Powered device dampens amygdala response to emotional stimuli: A peripheral effect-controlled within-subjects randomized dose-response fMRI trial

It is unclear if and how exogenous oxytocin (OT) reaches the brain to improve social behavior and cognition and what is the optimal dose for OT response. To better understand the delivery routes of intranasal OT administration to the brain and the …

Oxytocin: How Does This Neuropeptide Change Our Social Behavior?

Neuropeptides are small molecules that act as messengers between different brain regions. There are roughly 100 neuropeptides that are important for a variety of functions, including hunger, memory, and learning. Oxytocin is one such neuropeptide, …

The promise and pitfalls of intranasally administering psychopharmacological agents for the treatment of psychiatric disorders

Accumulating research demonstrates the potential of intranasal delivery of psychopharmacological agents to treat a range of psychiatric disorders and symptoms. It is believed that intranasal administration offers both direct and indirect pathways to …

The relationship between central and peripheral oxytocin concentrations: a systematic review and meta-analysis protocol

Background: Research examining the effects of oxytocin (OT) interventions on psychiatric, social-behavioral, and social-cognitive outcomes regularly collect peripheral levels of OT as markers of central bioavailability. Such inferences rest on the …

Do delivery routes of intranasally administered oxytocin account for observed effects on social cognition and behavior? A two-level model

Accumulating evidence demonstrates the important role of oxytocin (OT) in the modulation of social cognition and behavior. This has led many to suggest that the intranasal administration of OT may benefit psychiatric disorders characterized by social …

Low dose oxytocin delivered intranasally with Breath Powered device affects social-cognitive behavior: a randomized 4-way crossover trial with nasal cavity dimension assessment

Despite the promise of intranasal oxytocin (OT) for modulating social behavior, recent work has provided mixed results. This may relate to suboptimal drug deposition achieved with conventional nasal sprays, inter-individual differences in nasal …

Oxytocin Increases Heart Rate Variability in Humans at Rest: Implications for Social Approach-Related Motivation and Capacity for Social Engagement

Context: Oxytocin (OT) plays a key regulatory role in human social behaviour. While prior studies have examined the effects of OT on observable social behaviours, studies have seldom examined the effects of OT on psychophysiological markers such as …
