Preprint alert!!! We recorded directly from the human ventral tegmental area (VTA), the principal source of cortical dopaminergic innervation, while patients performed an instrumental learning task. 🧵👇 www.biorxiv.org/content/10.6...

@dotproduct.bsky.social's first first author paper is finally out in @sfnjournals.bsky.social! Her findings show that content-specific predictions fluctuate with alpha frequencies, suggesting a more specific role for alpha oscillations than we may have thought. With @jhaarsma.bsky.social. 🧠🟦 🧠🤖

Contents of visual predictions oscillate at alpha frequencies
Predictions of future events have a major impact on how we process sensory signals. However, it remains unclear how the brain keeps predictions online in anticipation of future inputs. Here, we combin...

Are interoception and mental health linked? Many assume so, with interoception even described as a psychiatric “p-factor.” But in our latest preprint, we were surprised to find little evidence for such a connection. www.medrxiv.org/content/10.1... 🧵 Thread with our reflections on the matter 👇

Interoceptive Ability is Unrelated to Mental Health Symptoms: Evidence From a Large Scale Multi-Domain Psychophysical Investigation
Interoception-the sensing and perception of the internal viscera-is widely cast as a transdiagnostic mechanism linking brain-body interaction to mental illness. Prevailing models propose that altered ...

Spoke at my first #OHBM in Brisbane 🇦🇺 and received a Merit Abstract Award. We conducted the first human study recording LFPs from the VTA during reward learning. Signals reflected reward outcomes and expected value. Grateful to @vlitvak.bsky.social, mentors and our team. Manuscript 🔜 #OHBM2025 🧠
