Grateful to Tuula Kieseppä (Editor) and the reviewers for their insightful feedback, and deeply grateful to Lauri Parkkonen and Riitta Hari for their mentorship and support at @aalto.fi, and to Business Finland and the Norman Loveless Memorial Fund for supporting this work.

We highlight valuable work by many labs and researchers, including @leoschilbach.bsky.social, @dimitrisbolis.bsky.social, @introspection.bsky.social, @thomasinselmd, and many others, alongside previous work with Niclas (e.g., the ConNECT approach - frontiersin.org/journals/hum...).

We outline historical shifts between individual-centered and relational paradigms in psychiatry and neuroscience, introduce multi-person approaches to psychiatry and psychotherapy, and synthesize these developments into a relational framework for advancing mental health research.

We emphasize the central role of social interaction and intersubjectivity, and the need to rigorously measure real-life, dynamic exchanges, moving beyond single-person approaches.

Where we describe and integrate scientific developments highlighting the importance of adding a social lens to psychiatry and mental health.

🧠Excited to share our new paper with

The social, decoupled self: interpersonal synchronization of breathing alters intrapersonal cardiorespiratory coupling People synchronize their periodic behavioural and physiological rhythms with each other during social interaction. While this interpersonal synchronization has largely been associated with positive ef...

🫁❤️New preprint out: The social, decoupled self

We show effects of interpersonal synchronization of physiological rhythms on intrapersonal cardiorespiratory coupling: when we sync our breathing, our breathing–heart rhythms decouple, with a perturbed phase-relationship

In our Trends in Cogn Sci paper we point to the connectivity crisis in task-based human EEG/MEG research: many connectivity metrics, too little replication. Time for community-wide benchmarking to build robust, generalisable measures across labs & tasks. www.sciencedirect.com/science/arti...

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.

Stomach–brain coupling indexes a dimensional signature of mental health - Nature Mental Health Using a relatively large and diverse sample of mostly young adults, this study by Banellis, Rebollo and colleagues examines associations between regional stomach–brain coupling and mental health and i...

🧠🥬 Your gut really does talk to your brain

A new study links stronger stomach–brain synchrony to worse mental health. Anxiety, depression, and stress all showed ties to this gut-brain rhythm.

The self-reference memory bias is preceded by an other-reference bias in infancy - Nature Communications A classic feature of human memory is that we remember information better when it refers to ourselves. Here, the authors show that before the emergence of self-concept, infants instead remember informa...

Sharing our new paper published today in Nature Communications. In my view, this is our clearest demonstration to date that something profoundly changes in how infants encode the world around them before and after the emergence of self-representation. www.nature.com/articles/s41...

Overview of the simulation strategy and analysis. a) Pial and white matter boundaries surfaces are extracted from anatomical MRI volumes. b) Intermediate equidistant surfaces are generated between the pial and white matter surfaces (labeled as superficial (S) and deep (D) respectively). c) Surfaces are downsampled together, maintaining vertex correspondence across layers. Dipole orientations are constrained using vectors linking corresponding vertices (link vectors). d) The thickness of cortical laminae varies across the cortical depth (70–72), which is evenly sampled by the equidistant source surface layers. e) Each colored line represents the model evidence (relative to the worst model, ΔF) over source layer models, for a signal simulated at a particular layer (the simulated layer is indicated by the line color). The source layer model with the maximal ΔF is indicated by “˄”. f) Result matrix summarizing ΔF across simulated source locations, with peak relative model evidence marked with “˄”. g) Error is calculated from the result matrix as the absolute distance in mm or layers from the simulated source (*) to the peak ΔF (˄). h) Bias is calculated as the relative position of a peak ΔF(˄) to a simulated source (*) in layers or mm.

🚨🚨🚨PREPRINT ALERT🚨🚨🚨
Neural dynamics across cortical layers are key to brain computations - but non-invasively, we’ve been limited to rough "deep vs. superficial" distinctions. What if we told you that it is possible to achieve full (TRUE!) laminar (I, II, III, IV, V, VI) precision with MEG!

Does brain activity cause consciousness? A thought experiment The authors of this Essay examine whether action potentials cause consciousness in a three-step thought experiment that assumes technology is advanced enough to fully manipulate our brains.

The craziest paper I have ever done is this thought experiment with Albert Gidon and Matt Larkum.

In the first journal, reviewer 1 recommended that we should not try to publish this; reviewer 2 called it "wacky". Thanks for the motivation: A sequel is coming up!

Lovely work — and yet another proof that perceptual integration, likely based on recurrent connections, can occur without awareness during the attentional blink.
