Our data show specific alterations of self-generated sensations across different sensory modalities (touch and interoception) and at different processing stages (spinal and cortical), supporting the hypothesis of schizophrenia as a self-disorder.

We also find differences in heartbeat evoked potentials, which are larger for interoceptive focus.

We find that psychosis patients exhibit more neural activity in response to self-touch in STG and a reduced difference in latencies for SEPs during self- and other-touch already at the spinal cord level.

Interesting! I recently discovered Baudrillard and am a big fan 😅. Cool to see thoughts on how this applies to neuroscience!

PANEL 1: MATTIE is talking to a MAN as they walk on the street. The MAN is typing on his phone. MATTIE: What do you wanna do tonight? MAN: Hmm…! MAN: What…do…I…want…to…do…tonight? PANEL 2: MATTIE rolls her eyes. The phone pipes up as well. MATTIE: Are you asking a chatbot? Come on. PHONE: SEEING FRIENDS IS ALWAYS A GREAT WAY TO SEE YOUR FRIENDS. MAN: Oh, are you A.I. SHAMING ME? Wow. I didn't think you were a bigot. PANEL 3: MATTIE, arms spread wide. The MAN strokes his chin. MATTIE: What? Nobody was doing this a year ago. It's completely unnecessary! MAN: Huh, that's true. I wonder why that happened. PANEL 4: The MAN types on his phone, brow furrowed. MAN: Why…am…I…doing…this

We are super happy to share this self-touch / interoception research study in psychosis 🎉 from Rebecca Boehme’s lab

Today we held the initiation meeting for my study "PGD-psi" on psilocybin for prolonged / complicated grief 😊

Autonomic physiological coupling of the global fMRI signal Nature Neuroscience - The brain and body are necessarily connected. Here the authors show that brain blood flow and electrical activity are coupled with systemic physiological changes in the body.

First post on an exciting new manuscript online today @natneuro.nature.com - in collab with @lucinauddin.bsky.social and Catie Chang. We take a fresh look at the physiological dynamics associated with the global signal 🧠 ...

We know that in addition to exteroceptive mechanisms, interoceptive chemosensation is also critical for regulating physiology/behavior.

We find that an enteric neuron in worms senses ingested salts via a variant ionotropic receptor (IR like the fly IRs) to regulate salt stress. 1/n

The ancient psychedelics myth: ‘People tell tourists the stories they think are interesting for them’ The narrative of ancient tribes around the world regularly using ayahuasca and magic mushrooms in healing practices is a popular one. Is it true?

People often claim psychedelics have been used globally, for millennia, & in rituals of psychological healing.

In today's Guardian Long Read, I show what these stories get wrong & why the reality is far more interesting: www.theguardian.com/science/2025...

Female bonobos form coalitions against males to secure their social status and reduce sex differences in power, according to a paper in Communications Biology. The study suggests the impact of male aggression is mitigated by females grouping together. go.nature.com/4d60a3f 🧪

I also don't like the expressions "complicated" or "prolonged" grief.
The linked article was not about grief, but here is one we wrote about grief, body perception, and touch www.tandfonline.com/doi/pdf/10.1...
What brought me to research this topic? My own grief experiences.

Had the pleasure to give a lecture at Uppsala University last week 😊.

I presented our recent study on ketamine and the self www.nature.com/articles/s41... and my upcoming clinical trial on psilocybin for complicated grief

New paper from our lab now in @nature.com . We show that our brains use basis functions or "building blocks" to navigate social interactions. Rather than tracking every individual separately, social information is compressed into patterns that can be flexibly combined. www.nature.com/articles/s41...

Our paper in Nature (@mkwittmann.bsky.social et al.): the brain does not only process the *identity* of a person but primarily our *relationship* to them. Even on a neural level, who someone is *in relation to others* is key. www.nature.com/articles/s41...
