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...

@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. 🧠🟦 🧠🤖

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 ...

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 👇

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 🔜
