Physiology and Behavior

In this episode I chat with Izelle Labuschagne, who is the founder of the Complete Thesis support group, about reproducible science [3:42], social media for academics [21:20], and responding to reviewer comments [39:25].

This is the audio version of a paper I recently co-authored in Trends in Cognitive Sciences, titled "How podcasts can benefit scientific communities". I'm reading the preprint version of the article, which is very similar to the published version.

This was a talk I recently did on social media for academics. I cover both why and how academics can use social media to boost their academic careers. The slides are available here.

Enjoy!

This episode is the audio version of our paper, titled "An Allostatic Theory of Oxytocin", that was recently published in Trends in Cognitive Sciences.

Here is the abstract:

Oxytocin has garnered considerable interest for its role in social behavior, as well as for the potential of intranasal administration to treat social difficulties. How- ever, current theoretical models for the role of oxytocin in social behavior pay little consideration to its evolutionary and developmental history. This article aims to broaden our understanding of the role of oxytocin in social behavior by adopting an ethological approach through the lens of Nikolaas Tinbergen’s 'four questions' – how does oxytocin work; how does the role of oxytocin change during development; how does oxytocin enhance survival; and how did the oxytocin system evolve? We argue that oxytocin is most accurately described as an allostatic hormone that modulates both social and non-social behavior by maintaining stability through changing environments.

The main hesitation I hear from researchers when it comes to social media is that they've got nothing to share. In this short clip, I show you can you can share ten different bits of information, across different platforms, using just one idea.

Here's the video version of this clip.

This is a talk a recently gave at the university of Copenhagen in which I discuss ways we can improve the precision of oxytocin research.

Here is the talk abstract:

The neuropeptide oxytocin has garnered considerable interest for its role in social behavior and its potential for the treatment of psychiatric illnesses characterised by social dysfunction. However, initial excitement has turned to disappointment with some studies failing to replicate earlier results, which has been attributed to issues surrounding research methods, mechanistic understanding, and theory development. In this talk, I will discuss efforts to improve research design to enhance reproducibility, including precise sample size estimation, synthetic datasets, and ways to test evidence for null models. I will also describe two lines of research aiming to better understand oxytocin signalling mechanisms: i) Research identifying whole brain voxel-by-voxel gene expression patterns of the oxytocin receptor (OXTR) gene and its association with mental states via a large-scale fMRI meta-analysis of 14,371 studies and ii) data from two clinical trials demonstrating that compared to placebo, 8IU intranasal oxytocin (but not 24IU intranasal oxytocin or 1IU intravenous oxytocin) modulates social cognition, pupil diameter, and neural activity. Altogether, these studies provide the first steps towards identifying targets for oxytocin receptor engagement in the human brain and suggest that a lower 8IU intranasal dose might be more efficacious than the conventional 24IU dose. I will close by presenting my new theory of oxytocin’s role in human behaviour, which proposes that oxytocin modulates both social and non-social behaviour to maintain stability in changing environments.
