New Paper by my post-doc how observational learning shapes the avoidance of threats.
Participants are willing to take a longer route, if this way avoids a socially learned threat.
The decision to avoid was further associated with a route that was closer to the wall.

Might focused ultrasound one day replace DBS?

UK Scientists built a 256-panel focused ultrasound helmet that can precisely target deep brain regions. Using theta-burst TUS, they stimulated the LGN and found visual cortex activity with effects lasting up to 40 minutes.

Blerg. Preregistration should elevate our understanding of the importance of exploration, not affirmative action our past bad habits that everything was always anticipated in advance.

David Ryan Miller @davidryanmiller.com · 26d

Love it when you 1) do a proper preregistration, 2) find an unexpected finding in the course of examining your preregistered hypotheses, 3) present the unexpected finding as exploratory, and 4) a reviewer HAMMERS you for "undermining the integrity of the preregistration process?" 🫠

Online Now: The cognitive side of communication in social insects

The cognitive side of communication in social insects

Social insects rely on multiple communication channels. These channels have traditionally been considered innate, eliciting stereotyped responses. However, recent research has shown that cognitive modulation occurs in communication contexts long assumed to be entirely genetically encoded, thus revealing a previously unrecognized cognitive plasticity in social insect communication.

I think it's time to retire the idea that oxytocin is exclusively a 'social' hormone.

In our latest preprint, led by @kjerstimw.bsky.social, we argue that oxytocin should be reframed as a behavioral flexibility hormone osf.io/preprints/os...

Abstract

Oxytocin is a neuropeptide that has historically been recognised for its role in childbirth, lactation, and sexual reproduction. Subsequently, research expanded its influence to include social bonding and behaviors, emphasising its role in facilitating interpersonal relationships. More recent studies, however, have revealed its broader influence, extending to non-social behaviors and cognitive processes, underscoring its ability to modulate a diverse array of behavioral and mental functions. This evolving understanding calls for a critical re-evaluation of oxytocin’s classification as a “social” hormone. The Allostatic Theory of Oxytocin, which integrates both psychological and physiological dimensions, provides an alternative framework that accounts for how oxytocin modulates both social and non-social behaviors. At the core of this framework is behavioral flexibility, which is essential for adapting to dynamic environments. In this review, we explore the role of oxytocin in facilitating behavioral and cognitive flexibility using mechanistic, survival, and evolutionary perspectives. Additionally, we focus on the interactions between oxytocin and other signalling systems that influence behavioral flexibility. Collectively, our findings underscore the benefits of reframing oxytocin’s function in behavior within a broader framework that encompasses both social and non-social aspects. This more expansive perspective not only deepens our understanding of oxytocin’s multifaceted roles but also opens avenues for novel research approaches.
